Abstract
KEY MESSAGE CYP72D19, the first functional gene of the CYP72D subfamily, catalyzes the C-2 hydroxylation of abietane-type diterpenoids. The abietane-type diterpenoids, e.g., triptolide, tripdiolide, and 2-epitripdiolide, are the main natural products for the anti-tumor, anti-inflammatory, and immunosuppressive activities of Tripterygium wilfordii, while their biosynthetic pathways are not resolved. Here, we cloned and characterized the CYP72D19-catalyzed C-2 hydroxylation of dehydroabietic acid, a compound that has been proven to be a biosynthetic intermediate in triptolide biosynthesis. Through molecular docking and site-directed mutagenesis, L386, L387, and I493 near the active pocket were found to have an important effect on the enzyme activity, which also indicates that steric hindrance of residues plays an important role in function. In addition, CYP72D19 also catalyzed a variety of abietane-type diterpenoids with benzene ring, presumably because the benzene ring of the substrate molecule stabilized the C-ring, allowing the protein and the substrate to form a relatively stable spatial structure. This is the first demonstration of CYP72D subfamily gene function. Our research provides important genetic elements for the structural modification of active ingredients and the heterologous production of other 2-hydroxyl abietane-type natural products.

Abstract
The presence of anticancer clerodane diterpenoids is a chemotaxonomic marker for the traditional Chinese medicinal plant Scutellaria barbata, although the molecular mechanisms behind clerodane biosynthesis are unknown. Here, we report a high-quality assembly of the 414.98 Mb genome of S. barbata into 13 pseudochromosomes. Using phylogenomic and biochemical data, we mapped the plastidial metabolism of kaurene (gibberellins), abietane, and clerodane diterpenes in three species of the family Lamiaceae (Scutellaria barbata, Scutellaria baicalensis, and Salvia splendens), facilitating the identification of genes involved in the biosynthesis of the clerodanes, kolavenol, and isokolavenol. We show that clerodane biosynthesis evolved through recruitment and neofunctionalization of genes from gibberellin and abietane metabolism. Despite the assumed monophyletic origin of clerodane biosynthesis, which is widespread in species of the Lamiaceae, our data show distinct evolutionary lineages and suggest polyphyletic origins of clerodane biosynthesis in the family Lamiaceae. Our study not only provides significant insights into the evolution of clerodane biosynthetic pathways in the mint family, Lamiaceae, but also will facilitate the production of anticancer clerodanes through future metabolic engineering efforts.

Abstract
Rosemary (Salvia rosmarinus) is considered a sacred plant because of its special fragrance and is commonly used in cooking and traditional medicine. Here, we report a high-quality chromosome-level assembly of the S. rosmarinus genome of 1.11 Gb in size; the genome has a scaffold N50 value of 95.5 Mb and contains 40 701 protein-coding genes. In contrast to other diploid Labiataceae, an independent whole-genome duplication event occurred in S. rosmarinus at approximately 15 million years ago. Transcriptomic comparison of two S. rosmarinus cultivars with contrasting carnosic acid (CA) content revealed 842 genes significantly positively associated with CA biosynthesis in S. rosmarinus. Many of these genes have been reported to be involved in CA biosynthesis previously, such as genes involved in the mevalonate/methylerythritol phosphate pathways and CYP71-coding genes. Based on the genomes and these genes, we propose a model of CA biosynthesis in S. rosmarinus. Further, comparative genome analysis of the congeneric species revealed the species-specific evolution of CA biosynthesis genes. The genes encoding diterpene synthase and the cytochrome P450 (CYP450) family of CA synthesis-associated genes form a biosynthetic gene cluster (CPSs-KSLs-CYP76AHs) responsible for the synthesis of leaf and root diterpenoids, which are located on S. rosmarinus chromosomes 1 and 2, respectively. Such clustering is also observed in other sage (Salvia) plants, thus suggesting that genes involved in diterpenoid synthesis are conserved in the Labiataceae family. These findings provide new insights into the synthesis of aromatic terpenoids and their regulation.

Abstract
Overexpression and antisense expression of Sm4CL2 re-directed the biosynthesis of salvianolic acids and tanshinones in Salvia miltiorrhiza hairy roots. Danshen (Salvia miltiorrhiza Bunge) is a widely used traditional Chinese medicine and its main active ingredients are water-soluble phenolic acids and lipophilic diterpenoids which are produced through the phenylpropanoid pathway and terpenoid pathway, respectively. 4-Coumaric acid: Coenzyme A ligase (4CL) is a key enzyme in the phenylpropanoid metabolism. We had obtained Sm4CL2-overexpressing (Sm4CL2-OE) and antisense Sm4CL2-expressing (anti-Sm4CL2) danshen hairy roots over ten years ago. In the follow-up study, we found that total salvianolic acids in Sm4CL2-OE-4 hairy roots increased to 1.35 times of the control-3, and that in anti-Sm4CL2-1 hairy roots decreased to 37.32% of the control-3, but tanshinones in anti-Sm4CL2-1 was accumulated to 1.77 ± 0.16 mg/g of dry weight, compared to undetectable in Sm4CL2-OE-4 and the control-3 hairy roots. Interestingly, Sm4CL2-OE-4 hairy roots contained more lignin, 1.36 times of the control-3, and enhanced cell wall and xylem lignification. Transcriptomic analysis revealed that overexpression of Sm4CL2 caused the upregulation of other phenylpropanoid pathway genes and antisense Sm4CL2 expression resulted in the downregulation of other phenylpropanoid pathway genes but activated the expression of terpenoid pathway genes like SmCYP76AK5, SmGPPS.SSUII.1 and SmDXS2. Protein-protein interaction analysis suggested that Sm4CL2 might interact with PAL, PAL4, CSE, CCoAOMT and SmCYP84A60, and appeared to play a key role in the interaction network. The tracking work in this study proved that Sm4CL2 could redirect both salvianolic acids and tanshinones biosynthesis possibly through synergistically regulating other pathway genes. It also indicated that genetic modification of plant secondary metabolism with biosynthetic gene might cause other responses through protein-protein interactions.

Abstract
Abietic acid (AA), dehydroabietic acid (DHA) and triptoquinones (TQs) are bioactive abietane-type diterpenoids, which are present in many edible vegetables and medicinal herbs with health-promoting properties. Evidence suggests that beneficial effects of diterpenes operate, at least in part, through effects on cells in the immune system. Dendritic cells (DCs) are a key type of leukocyte involved in the initiation and regulation of the immune/inflammatory response and natural or synthetic compounds that modulate DC functions could be potential anti-inflammatory/immunomodulatory agents. Herein, we report the screening of 23 known semisynthetic AA and DHA derivatives, and TQs, synthesized previously by us, in a multi-analyte DC-based assay that detects inhibition of pro-inflammatory cytokine production. Based on the magnitude of the inhibitory effect observed and the number of cytokines inhibited, a variety of activities among compounds were observed, ranging from inactive/weak to very potent inhibitors. Structurally, either alcohol or methyl ester substituents on ring A along with the introduction of aromaticity and oxidation in ring C in the abietane skeleton were found in compounds with higher inhibitory properties. Two DHA derivatives and two TQs exhibited a significant inhibition in all pro-inflammatory cytokines tested and were further investigated. The results confirmed their ability to inhibit, dose dependently, LPS-stimulated expression of the co-stimulatory molecules CD40 and/or CD86 and the production of the pro-inflammatory cytokines IL-1β, IL-6, IL-12 and TNFα. Our results demonstrate that DC maturation process can be targeted by semisynthetic DHA derivatives and TQ epimers and indicate the potential of these compounds as optimizable anti-inflammatory/immunomodulatory agents.

Abstract
Phenolic acids are the major bioactive metabolites produced in Salvia miltiorrhiza, a traditional Chinese medicine called Danshen. Many phytohormone elicitor treatments induce phenolic acid biosynthesis, even though the underlying mechanism remains obscure. Expression pattern analysis showed that SmMAPK3 was highly expressed in leaves, and SmMAPK3 was significantly induced by salicylic acid (SA) and methyl jasmonate (JA). Bioinformatics analysis revealed that SmMAPK3 belongs to group A and contains a TEY motif in the activation loop together with three conserved regions (P-loop, C-loop and CD-domain). A previous study speculated that SmMAPK3 is likely a positive regulator in the biosynthesis of phenolic acids in S. miltiorrhiza. In this study, overexpression of SmMAPK3 increased phenolic acid biosynthetic gene expression and enhanced the accumulation of phenolic acids in S. miltiorrhiza plantlets. Yeast two-hybrid (Y2H) analysis and firefly luciferase complementation imaging (LCI) assays revealed that SmMAPKK2/4/5/7-SmMAPK3-SmJAZs form a cascade that regulates the accumulation of phenolic acids. In summary, this work deepens our understanding of the posttranscriptional regulatory mechanisms of phenolic acid biosynthesis and sheds new light on metabolic engineering in S. miltiorrhiza.

Abstract
Tanshinones are the bioactive diterpenoid constituents of the traditional Chinese medicinal herb Danshen (Salvia miltiorrhiza), and are examples of the phenolic abietanes widely found within the Lamiaceae plant family. Due to the significant interest in these labdane-related diterpenoid natural products, their biosynthesis has been intensively investigated. In addition to providing the basis for metabolic engineering efforts, this work further yielded pioneering insights into labdane-related diterpenoid biosynthesis in the Lamiaceae more broadly. This includes stereochemical foreshadowing of aromatization, with novel protein domain loss in the relevant diterpene synthase, as well as broader phylogenetic conservation of the relevant enzymes. Beyond such summary of more widespread metabolism, formation of the furan ring that characterizes the tanshinones also has been recently elucidated. Nevertheless, the biocatalysts for the pair of demethylations remain unknown, and the intriguing potential connection of these reactions to the further aromatization observed in the tanshinones are speculated upon here.

Abstract
The effect of spontaneous fermentation by lactic acid bacteria on the extraction yield of bioactive compounds and antioxidant activity from rosemary leaf extracts was investigated using high-performance thin-layer chromatography (HPTLC). Brining and spontaneous fermentation with lactic acid bacteria more than doubled extraction of polyphenolics and antioxidants from the rosemary leaves. The results show that lactic acid fermentation enhances antioxidant activity in extracts by increasing the total phenolic content but does not increase extraction of phytosterols. Increased extraction of phenolic oxidants during fermentation assisted extraction, results from the in situ generated natural eutectic solvent from the plant sample. ATR-FTIR spectra from the bioactive bands suggests that this increased antioxidant activity is associated with increased extraction of rosmarinic acid, depolymerised lignin, abietane diterpenoids and 15-hydroxy-7-oxodehydroabietic acid.

Abstract
Aurora B kinase is aberrantly overexpressed in various tumors and shown to be a promising target for anti-cancer therapy. In human oral squamous cell carcinoma (OSCC), the high protein level of Aurora B is required for maintaining of malignant phenotypes, including in vitro cell growth, colony formation, and in vivo tumor development. By molecular modeling screening of 74 commercially available natural products, we identified that Tanshinone IIA (Tan IIA), as a potential Aurora B kinase inhibitor. The in silico docking study indicates that Tan IIA docks into the ATP-binding pocket of Aurora B, which is further confirmed by in vitro kinase assay, ex vivo pull-down, and ATP competitive binding assay. Tan IIA exhibited a significant anti-tumor effect on OSCC cells both in vitro and in vivo, including reduction of Aurora B and histone H3 phosphorylation, induction of G2/M cell cycle arrest, increase the population of polyploid cells, and promotion of apoptosis. The in vivo mouse model revealed that Tan IIA delayed tumor growth of OSCC cells. Tan IIA alone or in combination with radiation overcame radioresistance in OSCC xenograft tumors. Taken together, our data indicate that Tan IIA is an Aurora B kinase inhibitor with therapeutic potentials for cancer treatment.

Abstract
MIR396b had been cloned and overexpressed in Salvia miltiorrhiza hairy roots. MiR396b targets SmGRFs, SmHDT1, and SmMYB37/4 to regulate cell growth and secondary metabolism in S. miltiorrhiza hairy roots. Danshen (Salvia miltiorrhiza Bunge) is a valuable medicinal herb with two kinds of clinically used natural products, salvianolic acids and tanshinones. miR396 is a conserved microRNA and plays extensive roles in plants. However, it is still unclear how miR396 works in S. miltiorrhiza. In this study, an smi-MIR396b has been cloned from S. miltiorrhiza. Overexpression of miR396b in danshen hairy roots inhibited hairy root growth, reduced salvianolic acid concentration, but enhanced tanshinone accumulation, resulting in the biomass and total salvianolic acids respectively reduced to 55.5 and 72.1% of the control and total tanshinones increased up to 1.91-fold of the control. Applied degradome sequencing, 5'RLM-RACE, and qRT-PCR, 13 targets for miR396b were identified including seven conserved SmGRF1-7 and six novel ones. Comparative transcriptomics and microRNomics analysis together with qRT-PCR results confirmed that miR396b targets SmGRFs, SmHDT1, and SmMYB37/4 to mediate the phytohormone, especially gibberellin signaling pathways and consequentially resulted in the phenotype variation of miR396b-OE hairy roots. Furthermore, miR396b could be activated by methyl jasmonate, abscisic acid, gibberellin, salt, and drought stresses. The findings in this study indicated that smi-miR396b acts as an upstream and central regulator in cell growth and the biosynthesis of tanshinones and salvianolic acids, shedding light on the coordinated regulation of plant growth and biosynthesis of active ingredients in S. miltiorrhiza.

Abstract
S. miltiorrhiza is a well-known Chinese herb for the clinical treatment of cardiovascular and cerebrovascular diseases. Tanshinones and phenolic acids are the major secondary metabolites and significant pharmacological constituents of this plant. Kelch repeat F-box (KFB) proteins play important roles in plant secondary metabolism, but their regulation mechanism in S. miltiorrhiza has not been characterized. In this study, we systematically characterized the S. miltiorrhiza KFB gene family. In total, 31 SmKFB genes were isolated from S. miltiorrhiza. Phylogenetic analysis of those SmKFBs indicated that 31 SmKFBs can be divided into four groups. Thereinto, five SmKFBs (SmKFB1, 2, 3, 5, and 28) shared high homology with other plant KFBs which have been described to be regulators of secondary metabolism. The expression profile of SmKFBs under methyl jasmonate (MeJA) treatment deciphered that six SmKFBs (SmKFB1, 2, 5, 6, 11, and 15) were significantly downregulated, and two SmKFBs (SmKFB22 and 31) were significantly upregulated. Tissue-specific expression analysis found that four SmKFBs (SmKFB4, 11, 16, and 17) were expressed preferentially in aerial tissues, while two SmKFBs (SmKFB5, 25) were predominantly expressed in roots. Through a systematic analysis, we speculated that SmKFB1, 2, and 5 are potentially involved in phenolic acids biosynthesis.

Abstract
The uptake and accumulation of cadmium (Cd) in Salvia miltiorrhiza (Bge.) negatively affects the quality of its harvested roots, and seriously threatens human health. This study investigates the effect of a microbial inoculant (MI) and garbage enzyme (GE) on Cd uptake, the accumulation of bioactive compounds, and the community composition of microbes in the rhizosphere soil of S. miltiorrhiza under Cd stress. S. miltiorrhiza seedlings were transplanted to Cd-contaminated pots and irrigated with an MI, GE, a combination of an MI and GE (MIGE) or water (control). The results indicated that treatments with an MI, GE or MIGE can reduce Cd uptake in S. miltiorrhiza. The MIGE treatment had greater efficiency in reducing Cd uptake than the control (reduction by 37.90%), followed by the GE (25.31%) and MI (5.84%) treatments. Treatments with an MI, GE and MIGE had no significant impact on fresh and dry root biomass. Relative to the control, the MI treatment had the highest efficiency in increasing the accumulation of total tanshinones (an increase of 40.45%), followed by the GE treatment (40.08%), with the MIGE treatment (9.90%) treatment not having a more favorable effect than the separate application of an MI or GE. The salvianolic acid content for all groups was higher than the standard prescribed by Chinese pharmacopoeia, notwithstanding a slightly lower level in the treated groups relative to the control. In addition, metagenomic analysis indicated changes in the relative abundance of soil microbes associated with the bioremediation of heavy metals. The relative abundances of Brevundimonas, Microbacterium, Cupriavidus and Aspergillus were significantly greater in the treated groups than in the Control. These results suggest that using MI and GE, either separately or together, may not only improve the quality of S. miltiorrhiza but may also facilitate the microbial remediation of soil contaminated with Cd.

Abstract
Phenolic acids and tanshinones are the two groups of pharmaceutically active metabolites in Salvia miltiorrhiza Bunge. Their contents are the key quality indicator to evaluate S. miltiorrhiza. bHLH transcription factors have important roles in regulation of plant specialised metabolism. In this study, an endogenous bHLH transcription factor, SmbHLH3, was identified and functionally analyzed. SmbHLH3 was presented in all the six tissues and mostly expressed in fibrous roots and flowers. It was localized to the nucleus. Overexpression of SmbHLH3 decreased both phenolic acids and tanshinones contents. Contents of caffeic acid and rosmarinic acid were both decreased to 50% of the control. And accumulation of salvianolic acid B was decreased as much as 62%. Content of cryptotanshinone, dihydrotanshinone I, tanshinone I and tanshinone IIA in SmbHLH3-overexpression lines were reduced 97%, 62%, 86% and 91%, respectively. In the transgenic lines, expression of C4H1, TAT and HPPR in phenolic acids pathways were reduced to about 43%, 66% and 77% of the control, respectively. For tanshinone biosynthetic pathways, transcripts of DXS3, DXR, HMGR1, KSL1, CPS1 and CYP76AH1 were reduced to 46%, 65%, 78%, 57%, 27% and 62% of the control, respectively. There was an E/G-box specific binding site in SmbHLH3, which may bind the E/G-box present in promoter region of these biosynthetic pathway genes. Y1H results indicated that SmbHLH3 could bind the promoter of TAT, HPPR, KSL1 and CYP76AH1. These findings indicated that SmbHLH3 downregulate both phenolic acids and tanshinone accumulation through directly suppressing the transcription of key enzyme genes.

Abstract
Rosemary and sage species from Lamiaceae contain high amounts of structurally related but diverse abietane diterpenes. A number of substances from this compound family have potential pharmacological activities and are used in the food and cosmetic industry. This has raised interest in their biosynthesis. Investigations in Rosmarinus officinalis and some sage species have uncovered two main groups of cytochrome P450 oxygenases that are involved in the oxidation of the precursor abietatriene. CYP76AHs produce ferruginol and 11-hydroxyferruginol, while CYP76AKs catalyze oxidations at the C20 position. Using a modular Golden-Gate-compatible assembly system for yeast expression, these enzymes were systematically tested either alone or in combination. A total of 14 abietane diterpenes could be detected, 8 of which have not been reported thus far. We demonstrate here that yeast is a valid system for engineering and reconstituting the abietane diterpene network, allowing for the discovery of novel compounds with potential bioactivity.

Abstract
Trichoderma atroviride develops a symbiont relationship with Salvia miltiorrhiza and this association involves a number of signaling pathways and proteomic responses between both partners. In our previous study, we have reported that polysaccharide fraction (PSF) of T. atroviride could promote tanshinones accumulation in S.miltiorrhiza hairy roots. Consequently, the present data elucidates the broad proteomics changes under treatment of PSF. Furthermore, we reported several previously undescribed and unexpected responses, containing gene expression patterns consistent with biochemical stresses and metabolic patterns inside the host. In summary, the PSF-induced tanshinones accumulation in S.miltiorrhiza hairy roots may be closely related to Ca2+ triggering, peroxide reaction, protein phosphorylation, and jasmonic acid (JA) signal transduction, leading to an increase in leucine-rich repeat (LRR) protein synthesis. This results in the changes in basic metabolic flux of sugars, amino acids, and protein synthesis, along with signal defense reactions. The results reported here increase our understanding of the interaction between T.atroviride and S.miltiorrhiza and specifically confirm the proteomic responses underlying the activities of PSF.

Abstract
Abietane diterpenoids, containing a quinone moiety, are synthesized in the roots of several Salvia species. Promising cytotoxicity and antiproliferative activities have been reported for these compounds in various cell and animal models. We have recently shown that aethiopinone, an o-naphto-quinone diterpene, produced in the roots of different Salvia species, is selectively cytotoxic against the A375 melanoma cell line. To enhance the synthesis of this abietane diterpenoid, we have engineered the plastidial 2-C-methyl-D-erythritol 4-phosphate-derived isoprenoid pathway in Salvia sclarea hairy roots by ectopic expression and plastid targeting of cyanobacterial genes encoding the 1-deoxy-D-xylulose 5-phosphate synthase or 1-deoxy-D-xylulose-5-phosphate reductoisomerase gene, the first two enzymatic steps of the plastidial MEP pathway, from which plant diterpenes primarily derive. Plastid-targeted expression of 1-deoxy-D-xylulose 5-phosphate synthase and 1-deoxy-D-xylulose-5-phosphate reductoisomerase proteins significantly enhanced the yield of aethiopinone by a 3-fold and about 6-fold increase, respectively. The accumulation of other abietane-type diterpenes (ferruginol, salvipisone, and carnosic acid), with interesting antiproliferative activity, was also increased. Compared to our previous data obtained by overexpressing the plant orthologous 1-deoxy-D-xylulose 5-phosphate synthase and 1-deoxy-D-xylulose-5-phosphate reductoisomerase genes in S. sclarea hairy roots, the results presented here confirm that the bacterial 1-deoxy-D-xylulose-5-phosphate reductoisomerase enzyme plays a major role than the DXS enzyme in the biosynthetic pathway of this class of compounds and that its ectopic expression does not conflict with active hairy root growth, resulting in a balanced trade-off between the transgenic hairy root final biomass and the increased content of o-naphto-quinone diterpenes, with interesting biological activities.

Abstract
Rosemary ethanol extract (REE) from Rosmarinus officinalis was identified by LC-ESI-MS/MS and 12 compounds were found. Among them, rosmarinic acid (389.78 μg/mg in REE), luteolin-3'-O-glucuronide (325.58 μg/mg), luteolin-5-O-glucuronide (120.92 μg/mg), and geniposide (120.83 μg/mg) are the major components. The antioxidant activity evaluation of REE by off-line HPLC methods indicated that among the 12 compounds, rosmarinic acid had the strongest scavenging activities in both DPPH· and ·OH. The cytotoxicity experiment showed that REE with the concentration ranges from 1 to 100 µg/ml did not significantly affect the cell viability of HeLa, while inhibitory rate reduced to 62.3% when the concentration was increased to 1,000 µg/ml. The results of intracellular antioxidation assay showed that the ability of REE in reducing the reactive oxygen species (ROS) in HeLa cells was higher than rosmanol, and lower than rosmarinic acid without cell toxicity. PRACTICAL APPLICATIONS: Plant polyphenols are essential components of functional foods, due to their antioxidant and enzyme inhibition activities. This paper is the first study about the quantification of antioxidant compounds, antioxidant activity evaluation, and their cellular antioxidant activity of polyphenols extract from R. officinalis toward HeLa cells. We aimed to elucidate the chemical composition and recognition of antioxidant components with DPPH and OH free radicals scavenging activity. In addition, the polyphenols dose-response correlations with cellular antioxidant activity were also determined. These results indicated that off-line HPLC method with DPPH and OH free radicals as markers is available for screening antioxidant activity of polyphenols from the mixture.

Abstract
Phenolic acids are important secondary metabolites produced in the Chinese medicinal plant Salvia miltiorrhiza, but little is known about the transcription factors involved in the regulation of tanshinone and phenolic acid biosynthesis. Here, a novel AP2/ERF transcription factor SmERF115 was isolated and functionally characterized. SmERF115 was most responsive to methyl jasmonate (MeJA) treatment and was localized in the nucleus. The phenolic acid production was increased in SmERF115-overexpressing hairy roots, but with a decrease in tanshinone content. In contrast, silencing of SmERF115 reduced the phenolic acid level, but increased tanshinone content. The expression of the key biosynthetic gene SmRAS1 was up-regulated in SmERF115 overexpression lines but was down-regulated in SmERF115-RNAi lines. Yeast one-hybrid (Y1H) assay and EMSA showed that SmERF115 directly binds to the promoter of SmRAS1, while dual-luciferase assays showed that SmERF115 could activate expression of SmRAS1 in vivo. Furthermore, global transcriptomic analysis by RNA sequencing revealed that expression of other genes such as PAL3, 4CL5, TAT3, and RAS4 was also increased in the overexpression line, implying that they were potentially involved in the SmERF115-mediated pathway. Our data show that SmERF115 is a positive regulator of phenolic acid biosynthesis, and may be a potential target for further metabolic engineering of phenolic acid biosynthesis in S. miltiorrhiza.

Abstract
The bHLH transcription factors have important role in regulation of plant growth, development, and secondary metabolism. Tanshinones are the major pharmaceutical components present in Salvia miltiorrhiza Bunge. It has been reported that bHLHs have functions in terpenoids biosynthesis. Here, we got a bHLH family member named SmbHLH10 which could positively regulate tanshinones biosynthesis in S. miltiorrhiza hairy roots. In the SmbHLH10-overexpressing line 6, four major tanshinones contents were reaching 2.51-fold (dihydrotanshinone I), 2.84-fold (cryptotanshinone), 2.89- fold (tanshinone I), 2.68-fold (tanshinone II A) of WT, respectively. The variation in tanshinones biosynthetic pathway gene transcription was generally consistent with tanshinones content. DXS2, DXS3 and DXR of MEP pathway were induced substantially, reaching 10-fold, 3-fold, 5.74-fold higher of the WT, respectively. The downstream pathway genes CPS1, CPS5 and CYP76AH1 were highest in line OE-SmbHLH10-6, reached 4.93, 16.29 and 3.27-fold of the WT, respectively, while KSL1's expression was highest in line OE-SmbHLH10-4, 4.64-fold of WT. Yeast one-hybrid assays results showed that SmbHLH10 could binds the predicted G-box motifs within the promoters of DXS2, CPS1 and CPS5. These findings indicated that SmbHLH10 could directly binds to G-box in the pathway genes' promotor, activate their expression and then upregulate tanshinones biosynthesis.

Abstract
The production of secondary metabolites by a new isolate of the purple sulfur bacterium Allochromatium vinosum, which had shown antibiotic activities during a preliminary study, revealed the production of several metabolites. Growth conditions suitable for the production of one of the compounds shown in the metabolite profile were established and compound 1 was purified. The molecular formula of compound 1 (C20H28O2) was determined by high resolution mass spectra, and its chemical structure by means of spectroscopic methods. The evaluation of these data revealed that the structure of the compound was identical to dehydroabietic acid, a compound known to be characteristically produced by conifer trees, but so far not known from bacteria, except cyanobacteria. The purified substance showed weak antibiotic activities against Bacillus subtilis and Staphylococcus lentus with IC50 values of 70.5 µM (±2.9) and 57.0 µM (±3.3), respectively.

Abstract
Jasmonates (JAs) are important plant hormones that regulate a variety of plant development and defense processes, including biosynthesis of secondary metabolites. The JASMONATE ZIM DOMAIN (JAZ) proteins act as negative regulators in the JA signaling pathways of plants. We first verified that methyl jasmonate (MeJA) enhanced the accumulation of both salvianolic acids and tanshinones in Salvia miltiorrhiza (Danshen) hairy roots by inducing the expression of their biosynthetic pathway genes. Nine JAZ genes were cloned from Danshen and their expression levels in hairy roots were all increased by treatment with MeJA. When analyzed in detail, however, SmJAZ8 showed the strongest expression in the induced hairy roots. Overexpression or RNAi of SmJAZ8 deregulated or up-regulated the yields of salvianolic acids and tanshinones in the MeJA-induced transgenic hairy roots, respectively, and transcription factors and biosynthetic pathway genes showed an expression pattern that mirrored the production of the compounds. Genetic transformation of SmJAZ8 altered the expression of other SmJAZ genes, suggesting evidence of crosstalk occurring in JAZ-regulated secondary metabolism. Furthermore, the transcriptome analysis revealed a primary-secondary metabolism balance regulated by SmJAZ8. Altogether, we propose a novel role for SmJAZ8 as a negative feedback loop controller in the JA-induced biosynthesis of salvianolic acids and tanshinones.

Abstract
Actinobactrial strains Rhodococcus erythropolis IEGM 267 and R. rhodochrous IEGM 107 were used to study biodegradation of dehydroabietic acid (DHA), a toxic tricyclic diterpenoid. The experiments were carried out in batch cultures of pre-grown rhodococci in the presence of 0.1% (v/v) n-hexadecane under aerobic conditions for 7 days. It was shown that R. erythropolis IEGM 267 and R. rhodochrous IEGM 107 partially and completely degraded DHA (500 mg/L), respectively. Characteristic physicochemical (reduced zeta potential) and morphological-physiological (increased average size of single cells and cell aggregates, increased root-mean-square roughness) changes in DHA-exposed actinobacteria were revealed. Products of DHA bioconversion by R. erythropolis IEGM 267 were analyzed and exhibited a previously unidentified metabolite 5α-hydroxy-abieta-8,11,13-triene-18-oat. The obtained experimental data widen the knowledge on the catalytic activity of rhodococci and their possible contribution to decontamination of natural ecosystems from pollutants.

Abstract
A Salvia miltiorrhiza R2R3-MYB gene, SmMYB9b , has been cloned and characterized. Overexpression of SmMYB9b resulted in a significant improvement of tanshinones, the lipophilic active ingredients in danshen hairy roots. Plant R2R3-MYB transcription factors play important roles in various physiological and biochemical processes. Danshen (Salvia miltiorrhiza bunge) is a valuable medicinal herb with tanshinones and salvianolic acids as the principal bioactive ingredients. A number of putative R2R3-MYB transcription factors have been identified in the plant, but their function remains to be studied. Here, we report the cloning of SmMYB9b, an S20 R2R3-MYB member and its regulatory properties. SmMYB9b contains an open reading frame of 792 bp in length and encodes a 264-amino acid protein. Its transcripts were most abundant in blooming flowers (except for calyces) and increased with flower development. Exogenous abscisic acid strongly activated its transcription. Gibberellins and methyl jasmonate also showed a time-dependent activation effect on its transcription, but to a weaker degree. Overexpression of SmMYB9b in danshen hairy roots enhanced tanshinone concentration to 2.16 ± 0.39 mg/g DW, a 2.2-fold improvement over the control. In addition to increased tanshinone concentration, the hairy root growth and lateral hairy root formation were also suppressed. KEGG pathway enrichment analysis with de novo RNAseq data indicated that stress-response-related metabolic pathways, such as the terpenoid and plant hormone signal transduction pathways, were significantly enriched, implying possible implication of SmMYB9b in such processes. Quantitative RT-PCR analysis showed that the transcription of terpenoid biosynthetic genes SmDXS2, SmDXR, SmGGPPS, and SmKSL1 was significantly up-regulated in danshen hairy roots over expressing SmMYB9b. These data suggest that overexpression of SmMYB9b results in enhanced tanshinone concentration through stimulation of the MEP pathway. The present findings shed new light on elucidating the roles of R2R3-MYB in the biosynthesis of diterpenoids in S. miltiorrhiza.

Abstract
This work aimed to investigate the effect of the two main components of rosemary extracts, namely rosmarinic acid (RA) and carnosic acid (CA), on the formation of advanced glycation end-products (AGEs) in vitro. In the bovine serum albumin (BSA)/glucose model, addition of RA and CA at 400μg/mL inhibited fluorescent AGEs by more than 90%, and carboxymethyl lysine (CML) and carboxyethyl lysine (CEL) by 82.7% and 75.2%, and 71.4% and 64.2%, respectively. Moreover, the addition of RA and CA at 400μg/mL inhibited fluorescent AGEs by more than 90% both in the BSA/glyoxal (GO) and BSA/methylglyoxal (MGO) models, the formation of CML by 64.9% and 53.9% in BSA/GO model, and CEL by 28.9% and 24.3% in BSA/MGO model, respectively. RA and CA also significantly decreased the concentration of MGO and protein carbonylation.

Abstract
Highly oxidized tanshinones are pharmacological ingredients extracted from the medicinal model plant Salvia miltiorrhiza and are mainly used to treat cardiovascular diseases. Previous studies have confirmed that cytochrome P450 mono-oxygenases (CYP450s) have a key function in the biosynthesis of tanshinones; however, no solid evidence links oxidation to the 2-oxoglutarate-dependent dioxygenase (2OGD) superfamily. Here, we identified 132 members of the DOXB and DOXC subfamilies of 2OGD by scanning the 2OG-FeII Oxy domain using a genome-wide strategy in S. miltiorrhiza. The DOXC class was phylogenetically divided into twelve clades. Combining phylogenetic relationships, differential expression and co-expression from various organs and tissues revealed that two 2OGDs were directly related to flavonoid metabolism, and that 13 2OGDs from different clades were predicted to be involved in tanshinone biosynthesis. Based on this insight into tanshinone production, we experimentally detected significant decreases in miltirone, cryptotanshinone, and tanshinone IIA (0.16-, 0.56-, and 0.56-fold, respectively) in 2OGD5 RNAi transgenic lines relative to the control lines using a metabonomics analysis. 2OGD5 was found to play a crucial role in the downstream biosynthesis of tanshinones following the hydroxylation of CYPs. Our results highlight the evolution and diversification of 2OGD superfamily members and suggest that they contribute to the complexity of tanshinone metabolites.

Abstract
Tripterygium wilfordii (Celastraceae) is a medicinal plant with anti-inflammatory and immunosuppressive properties. Identification of a vast array of unusual sesquiterpenoids, diterpenoids and triterpenoids in T. wilfordii has spurred investigations of their pharmacological properties. The tri-epoxide lactone triptolide was the first of many diterpenoids identified, attracting interest due to the spectrum of bioactivities. To probe the genetic underpinning of diterpenoid diversity, an expansion of the class II diterpene synthase (diTPS) family was recently identified in a leaf transcriptome. Following detection of triptolide and simple diterpene scaffolds in the root, we sequenced and mined the root transcriptome. This allowed identification of the root-specific complement of TPSs and an expansion in the class I diTPS family. Functional characterization of the class II diTPSs established their activities in the formation of four C-20 diphosphate intermediates, precursors of both generalized and specialized metabolism and a novel scaffold for Celastraceae. Functional pairs of the class I and II enzymes resulted in formation of three scaffolds, accounting for some of the terpenoid diversity found in T. wilfordii. The absence of activity-forming abietane-type diterpenes encouraged further testing of TPSs outside the canonical class I diTPS family. TwTPS27, close relative of mono-TPSs, was found to couple with TwTPS9, converting normal-copalyl diphosphate to miltiradiene. The phylogenetic distance to established diTPSs indicates neo-functionalization of TwTPS27 into a diTPS, a function not previously observed in the TPS-b subfamily. This example of evolutionary convergence expands the functionality of TPSs in the TPS-b family and may contribute miltiradiene to the diterpenoids of T. wilfordii.

Abstract
Drought decreases crop productivity more than any other type of environmental stress. Transcription factors (TFs) play crucial roles in regulating plant abiotic stress responses. The Arabidopsis thaliana gene DREB1A/CBF3, encoding a stress-inducible TF, was introduced into Salvia miltiorrhiza Ectopic expression of AtDREB1A resulted in increased drought tolerance, and transgenic lines had higher relative water content and Chl content, and exhibited an increased photosynthetic rate when subjected to drought stress. AtDREB1A transgenic plants generally displayed lower malondialdehyde (MDA), but higher superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activities under drought stress. In particular, plants with ectopic AtDREB1A expression under the control of the stress-induced RD29A promoter exhibited more tolerance to drought compared with p35S::AtDREB1A transgenic plants, without growth inhibition or phenotypic aberrations. Differential gene expression profiling of wild-type and pRD29A::AtDREB1A transgenic plants following drought stress revealed that the expression levels of various genes associated with the stress response, photosynthesis, signaling, carbohydrate metabolism and protein protection were substantially higher in transgenic plants. In addition, the amount of salvianolic acids and tanshinones was significantly elevated in AtDREB1A transgenic S. miltiorrhiza roots, and most of the genes in the related biosynthetic pathways were up-regulated. Together, these results demonstrated that inducing the expression of a TF can effectively regulate multiple genes in the stress response pathways and significantly improve the resistance of plants to abiotic stresses. Our results also suggest that genetic manipulation of a TF can improve production of valuable secondary metabolites by regulating genes in associated pathways.

Abstract
Cytochromes P450 (CYPs) play a key role in generating the structural diversity of terpenoids, the largest group of plant natural products. However, functional characterization of CYPs has been challenging because of the expansive families found in plant genomes, diverse reactivity and inaccessibility of their substrates and products. Here we present the characterization of two CYPs, CYP76AH3 and CYP76AK1, which act sequentially to form a bifurcating pathway for the biosynthesis of tanshinones, the oxygenated diterpenoids from the Chinese medicinal plant Danshen (Salvia miltiorrhiza). These CYPs had similar transcription profiles to that of the known gene responsible for tanshinone production in elicited Danshen hairy roots. Biochemical and RNA interference studies demonstrated that both CYPs are promiscuous. CYP76AH3 oxidizes ferruginol at two different carbon centers, and CYP76AK1 hydroxylates C-20 of two of the resulting intermediates. Together, these convert ferruginol into 11,20-dihydroxy ferruginol and 11,20-dihydroxy sugiol en route to tanshinones. Moreover, we demonstrated the utility of these CYPs by engineering yeast for heterologous production of six oxygenated diterpenoids, which in turn enabled structural characterization of three novel compounds produced by CYP-mediated oxidation. Our results highlight the incorporation of multiple CYPs into diterpenoid metabolic engineering, and a continuing trend of CYP promiscuity generating complex networks in terpenoid biosynthesis.

Abstract
Tanshinones are major bioactive diterpenoids of Salvia miltiorrhiza roots used for the treatment of cardiocerebral diseases. To develop effective elicitation and bioprocess strategies for the enhanced production of tanshinones, ultraviolet-B (UV-B) irradiation and methyl jasmonate (MeJA) elicitation were applied alone or in combination respectively in S. miltiorrhiza hairy root cultures. Our results showed 40-min UV-B irradiation at 40μW/cm(2) stimulated tanshinone production without any suppression of root growth, suggesting a new effective elicitor to S. miltiorrhiza hairy root cultures for tanshinone production. Moreover, the combined treatment of UV-B irradiation and MeJA exhibited synergistic effects on the expression levels of 3-hydroxy-3-methylglutaryl-CoA reductase (SmHMGR) and geranylgeranyl diphosphate synthase (SmGGPPS) genes in the tanshinone biosynthetic pathway. When hairy roots of 18-day-old cultures were exposed to the combined elicitation for 9days, the maximum production of tanshinone reached to 28.21mg/L, a 4.9-fold increase over the control. The combined elicitation of UV-B and MeJA was firstly used to stimulate the production of biologically important secondary metabolites in hairy root cultures.

Abstract
Salvia castanea Diels f. tomentosa Stib. is an endemic medicinal plant distributed in China, and the notably high content of tanshinone IIA in the root is proven effective for the therapy of heart diseases. Hairy root induction of this Salvia species was inoculated with Agrobacterium rhizogenes strain ATCC 15834. Transformed hairy root was cultured in 6,7-V liquid medium for growth kinetics assessment and elicitation. An S curve was present in the hairy root cultures based on the fresh and dry weights with an interval of 3 days. An optimum concentration of the applied elicitors (15 μM Ag(+), 200 μM methyl jasmonate, and 200 mg l(-1) yeast extract elicitor) benefitted both the growth status and tanshinone accumulation in the hairy root cultures. Tanshinone IIA contents were mostly stimulated 1.8-fold and 1.99-fold compared with the control by Ag(+) and methyl jasmonate elicitation, respectively. Yeast extract dramatically enhanced dry mass accumulation, while it promoted cryptotanshinone content of 2.84 ± 0.33 mg g(-1) dry weight at most in the hairy root cultures. Selected elicitors diversely influenced tanshinone accumulation in the time courses of hairy root cultures within 7 days. Furthermore, transcripts of selected genes in the tanshinone biosynthetic pathway were remarkably upregulated with elicitation. Yeast extract elicitor heightened 13.9-fold of isopentenyl diphosphate isomerase expression level at 12 h, while it increased 16.7-fold of geranylgeranyl diphosphate synthase transcript at 24 h compared with that of the control, which was more effective than Ag(+) and methyl jasmonate. This study provided a convenient hairy root culture system of S. castanea Diels f. tomentosa Stib. for tanshinone production for the first time.

Abstract
OBJECTIVES To evaluate sodium salicylate (NaSA) as an elicitor of rosmarinic acid (RA) and phenolic diterpenes, carnosol (C) and carnosic acid (CA) production, in a culture of Salvia officinalis shoots. RESULTS In sage shoots grown in vitro, 28 polyphenolic compounds (phenolic acids, flavonoids, and phenolic diterpenes) were identified. In shoots treated for 1 week with increasing NaSA concentrations, the content of C increased from 2.3 in control to 5.7 mg g(-1) DW in shoots treated with 500 µM NaSA. In shoots that were recovered on basal medium for 3 weeks, the maximal amount of C (14 mg/g(-1) DW) was with 150 µM NaSA treatment. In treated and recovered shoots, the increase in C was accompanied with a decrease in CA, resulting in 1.9-fold increase in the C/CA ratio. Accumulation of RA was not affected by the NaSA treatment. However, elicitation by NaSA was accompanied with growth retardation. CONCLUSIONS NaSA can improve C production in sage shoot culture, probably by stimulating the conversion of CA to C.

Abstract
Retinal pigment epithelial cells exert an important supporting role in the eye and develop adaptive responses to oxidative stress or high glucose levels, as observed during diabetes. Endogenous antioxidant defences are mainly regulated by Nrf2, a transcription factor that is activated by naturally-derived and electrophilic compounds. Here we investigated the effect of the Nrf2 activators dimethylfumarate (DMF) and carnosol on antioxidant pathways, oxygen consumption rate and wound healing in human retinal pigment epithelial cells (ARPE-19) cultured in medium containing normal (NG, 5mM) or high (HG, 25 mM) glucose levels. We also assessed wound healing using an in vivo corneal epithelial injury model. We found that Nrf2 nuclear translocation and heme oxygenase activity increased in ARPE cells treated with 10 μM DMF or carnosol irrespective of glucose culture conditions. However, HG rendered retinal cells more sensitive to regulators of glutathione synthesis or inhibition and caused a decrease of both cellular and mitochondrial reactive oxygen species. Culture in HG also reduced ATP production and mitochondrial function as measured with the Seahorse XF analyzer and electron microscopy analysis revealed morphologically damaged mitochondria. Acute treatment with DMF or carnosol did not restore mitochondrial function in HG cells; conversely, the compounds reduced cellular maximal respiratory and reserve capacity, which were completely prevented by N-acetylcysteine thus suggesting the involvement of thiols in this effect. Interestingly, the scratch assay showed that wound closure was faster in cells cultured in HG than NG and was accelerated by carnosol. This effect was reversed by an inhibitor of heme oxygenase activity. Moreover, topical application of carnosol to the cornea of diabetic rats significantly accelerated wound healing. In summary, these data indicate that culture of retinal epithelial cells in HG does not affect the activation of the Nrf2/heme oxygenase axis but influences other crucial oxidative and mitochondrial-dependent cellular functions. The additional effect on wound closure suggests that results obtained in in vitro experimental settings need to be carefully evaluated in the context of the glucose concentrations used in cell culture.

Abstract
Danshen, Salvia miltiorrhiza Bunge, is one of the most widely used herbs in traditional Chinese medicine, wherein its rhizome/roots are particularly valued. The corresponding bioactive components include the tanshinone diterpenoids, the biosynthesis of which is a subject of considerable interest. Previous investigations of the S. miltiorrhiza transcriptome have relied on short-read next-generation sequencing (NGS) technology, and the vast majority of the resulting isotigs do not represent full-length cDNA sequences. Moreover, these efforts have been targeted at either whole plants or hairy root cultures. Here, we demonstrate that the tanshinone pigments are produced and accumulate in the root periderm, and apply a combination of NGS and single-molecule real-time (SMRT) sequencing to various root tissues, particularly including the periderm, to provide a more complete view of the S. miltiorrhiza transcriptome, with further insight into tanshinone biosynthesis as well. In addition, the use of SMRT long-read sequencing offered the ability to examine alternative splicing, which was found to occur in approximately 40% of the detected gene loci, including several involved in isoprenoid/terpenoid metabolism.

Abstract
Plant pathogenic fungi are considered of significant economic importance for adversely affecting both quantitatively and qualitatively fresh and processed produce. Extracts of Salvia fruticosa were initially screened for their antifungal activity, and the ethyl acetate fraction, being the most active, was further analyzed using HPLC-SPE-NMR hyphenation. The methoxylated flavones hispidulin, salvigenin, and cirsimaritin and the diterpenes carnosic acid, carnosol, and 12-methoxycarnosic acid were identified as the major components of the extract. In addition, the concentration levels of all identified components were determined using q-NMR. The antifungal activity of the crude extract and selected phytochemicals was estimated against the fungal species Aspergillus tubingensis, Botrytis cinerea, and Penicillium digitatum. The estimated MIC and MFC values of the ethyl acetate extract of S. fruticosa, as well as three of its major constituents, carnosic acid, carnosol, and hispidulin, support their antifungal activity, especially against B. cinerea and P. digitatum, suggesting their potential use in food and agricultural systems.

Abstract
The highly conserved 70 kDa heat shock proteins (Hsp70) play an integral role in proteostasis such that dysregulation has been implicated in numerous diseases. Elucidating the precise role of Hsp70 family members in the cellular context, however, has been hampered by the redundancy and intricate regulation of the chaperone network, and relatively few selective and potent tools. We have characterized a natural product, novolactone, that targets cytosolic and ER-localized isoforms of Hsp70 through a highly conserved covalent interaction at the interface between the substrate-binding and ATPase domains. Biochemical and structural analyses indicate that novolactone disrupts interdomain communication by allosterically inducing a conformational change in the Hsp70 protein to block ATP-induced substrate release and inhibit refolding activities. Thus, novolactone is a valuable tool for exploring the requirements of Hsp70 chaperones in diverse cellular contexts.

Abstract
Salvia miltiorrhiza is a significant source of bioactive compounds providing human health effects. Here, we surveyed root yield and the active constituents' divergences of second generation S. miltiorrhiza (SP2) responding to a spaceflight environment. High-performance liquid chromatography was conducted for the comprehensive constituents' characterizations of 28 SP2 lines (224 individuals) and the ground control (eight individuals). The results showed that the mean fresh and dry weight of roots ranged from 116 to 172 g and 25 to 119 g, respectively, in SP2 lines. In addition, the mean contents of four tanshinone compounds (tanshinone I, tanshinone IIA, cryptotanshinone, and dihydrotanshinone I) of 28 SP2 lines varied from 0.32 to 1.04 mg · g(-1), 0.47 to 2.39 mg · g(-1), 0.25 to 1.60 mg · g(-1), and 0.53 to 1.67 mg · g(-1), respectively. Except for salvianolic acid B, which varied drastically from 72 % to 201 % of the ground control treatment, the other six phenolic acid contents of the 28 SP2 lines all increased after spaceflight. Principal component analysis was performed to obtain an overview of the distribution of all samples, and score plots clearly separated the SP2 accessions from ground controls. Moreover, a positive relationship was observed between tanshinone I and tanshinone IIA (r = 0.790, p < 0.01), and rosmarinic acid was positively correlated with salvianolic acid B (r = 0.728, p < 0.01). In conclusion, this study demonstrated that a spaceflight environment induced SP2 accessions remarkably in the variation of root yield and active constituent content.

Abstract
BACKGROUND AND AIMS Heartwood formation is a unique phenomenon of tree species. Although the accumulation of heartwood substances is a well-known feature of the process, the accumulation mechanism remains unclear. The aim of this study was to determine the accumulation process of ferruginol, a predominant heartwood substance of Cryptomeria japonica, in heartwood-forming xylem. METHODS The radial accumulation pattern of ferruginol was examined from sapwood and through the intermediate wood to the heartwood by direct mapping using time-of-flight secondary ion mass spectrometry (TOF-SIMS). The data were compared with quantitative results obtained from a novel method of gas chromatography analysis using laser microdissection sampling and with water distribution obtained from cryo-scanning electron microscopy. KEY RESULTS Ferruginol initially accumulated in the middle of the intermediate wood, in the earlywood near the annual ring boundary. It accumulated throughout the entire earlywood in the inner intermediate wood, and in both the earlywood and the latewood in the heartwood. The process of ferruginol accumulation continued for more than eight annual rings. Ferruginol concentration peaked at the border between the intermediate wood and heartwood, while the concentration was less in the latewood compared with the earlywood in each annual ring. Ferruginol tended to accumulate around the ray parenchyma cells. In addition, at the border between the intermediate wood and heartwood, the accumulation was higher in areas without water than in areas with water. CONCLUSIONS TOF-SIMS clearly revealed ferruginol distribution at the cellular level. Ferruginol accumulation begins in the middle of intermediate wood, initially in the earlywood near the annual ring boundary, then throughout the entire earlywood, and finally across to the whole annual ring in the heartwood. The heterogeneous timing of ferruginol accumulation could be related to the distribution of ray parenchyma cells and/or water in the heartwood-forming xylem.

Abstract
Forskolin, a complex labdane diterpenoid found in the root of Coleus forskohlii (Lamiaceae), has received attention for its broad range of pharmacological activities, yet the biosynthesis has not been elucidated. We detected forskolin in the root cork of C. forskohlii in a specialized cell type containing characteristic structures with histochemical properties consistent with oil bodies. Organelle purification and chemical analysis confirmed the localization of forskolin and of its simplest diterpene precursor backbone, (13R) manoyl oxide, to the oil bodies. The labdane diterpene backbone is typically synthesized by two successive reactions catalyzed by two distinct classes of diterpene synthases. We have recently described the identification of a small gene family of diterpene synthase candidates (CfTPSs) in C. forskohlii. Here, we report the functional characterization of four CfTPSs using in vitro and in planta assays. CfTPS2, which synthesizes the intermediate copal-8-ol diphosphate, in combination with CfTPS3 resulted in the stereospecific formation of (13R) manoyl oxide, while the combination of CfTPS1 and CfTPS3 or CfTPS4 led to formation of miltiradiene, precursor of abietane diterpenoids in C. forskohlii. Expression profiling and phylogenetic analysis of the CfTPS family further support the functional diversification and distinct roles of the individual diterpene synthases and the involvement of CfTPS1 to CfTPS4 in specialized metabolism and of CfTPS14 and CfTPS15 in general metabolism. Our findings pave the way toward the discovery of the remaining components of the pathway to forskolin, likely localized in this specialized cell type, and support a role of oil bodies as storage organelles for lipophilic bioactive metabolites.

Abstract
Fosmidomycin (100 micromol x L(-1)) which is the effective inhibitor of DXR, key enzyme in terpenoid MEP pathway, was used to treat with hairy roots of Salvia miltiorrhiza. The treated roots were harvested at 2, 4, 6, 8, 10, 16 and 21 d, mRNA level of SmDXR and tanshinone content in treated and negative control groups were detected. Results found that, after treated with fosmidomycin, color of S. miltiorrhiza hairy roots grew pale gradually comparing with controls; mRNA level of SmDXR in hairy roots varied as a shape of parabolic and the highest value achieved at the sixth day after treatment, then it decreased gradually; Content of four kinds of tanshinones were detected. Among of the four kinds of tanshinones, Tanshinone I content changed relatively little, while content of dihydrotanshinone I, cryptotanshinone and tanshinone II (A) decreased gradually in 21 days. The content of total tanshinones in NC groups was 5, 63 times more than FOS-treated roots in the 21th day. The previous results showed that SmDXR played an important role in the accumulation of tanshinone content in MEP pathway. Once the mRNA level of SmDXR was suppressed, the accumulation of secondary metabolites will be significantly affected.

Abstract
Tanshinones are abietane-type norditerpenoid quinone natural products found in a well-known traditional Chinese medicinal herb, Salvia miltiorrhiza Bunge. The copalyl diphosphate synthase of S. miltiorrhiza (SmCPS) is the key enzyme in the first step for transformation of geranylgeranyl diphosphate (GGPP) into miltiradiene, which has recently been identified as the precursor of tanshinones. Based on previous gene-to-metabolite network, this study examined the influences of various combined elicitors on the expression of SmCPS and production of tanshinones in S. miltiorrhiza hairy root cultures. Combined elicitors were composed of three classes of elicitors, a heavy metal ion (Ag⁺), a polysaccharide (yeast extract, YE), and a plant response-signalling compound (methyl jasmonate, MJ). YE + Ag⁺, Ag⁺ + MJ, YE + MJ, and YE + Ag⁺ + MJ were the combinations we tested. The effect of elicitors on the SmCPS expression level was detected by quantitative real-time PCR (qRT-PCR), and the tanshinones accumulation responses to elicitation were analysed by Ultra Performance Liquid Chromatography (UPLC) metabolite profiling. Of these combined elicitors, the expression of SmCPS was significantly enhanced by elicitation, especially at 24 h and 36 h. Of four tanshinones detected, the contents of cryptotanshinone and dihydrotanshinone I were enhanced by treatment with YE + Ag⁺, Ag⁺ + MJ, and YE + Ag⁺ + MJ. Our results indicate that appropriate combined elicitors can enhance tanshinones production in hairy root cultures.

Abstract
The misfolding and aggregation of amyloid-β (Aβ) peptides into amyloid fibrils is regarded as one of the causative events in the pathogenesis of Alzheimer's disease (AD). Tanshinones extracted from Chinese herb Danshen (Salvia Miltiorrhiza Bunge) were traditionally used as anti-inflammation and cerebrovascular drugs due to their antioxidation and antiacetylcholinesterase effects. A number of studies have suggested that tanshinones could protect neuronal cells. In this work, we examine the inhibitory activity of tanshinone I (TS1) and tanshinone IIA (TS2), the two major components in the Danshen herb, on the aggregation and toxicity of Aβ1-42 using atomic force microscopy (AFM), thioflavin-T (ThT) fluorescence assay, cell viability assay, and molecular dynamics (MD) simulations. AFM and ThT results show that both TS1 and TS2 exhibit different inhibitory abilities to prevent unseeded amyloid fibril formation and to disaggregate preformed amyloid fibrils, in which TS1 shows better inhibitory potency than TS2. Live/dead assay further confirms that introduction of a very small amount of tanshinones enables protection of cultured SH-SY5Y cells against Aβ-induced cell toxicity. Comparative MD simulation results reveal a general tanshinone binding mode to prevent Aβ peptide association, showing that both TS1 and TS2 preferentially bind to a hydrophobic β-sheet groove formed by the C-terminal residues of I31-M35 and M35-V39 and several aromatic residues. Meanwhile, the differences in binding distribution, residues, sites, population, and affinity between TS1-Aβ and TS2-Aβ systems also interpret different inhibitory effects on Aβ aggregation as observed by in vitro experiments. More importantly, due to nonspecific binding mode of tanshinones, it is expected that tanshinones would have a general inhibitory efficacy of a wide range of amyloid peptides. These findings suggest that tanshinones, particularly TS1 compound, offer promising lead compounds with dual protective role in anti-inflammation and antiaggregation for further development of Aβ inhibitors to prevent and disaggregate amyloid formation.

Abstract
OBJECTIVE To study the effects of Abscisic Acid (ABA) on the accumulation of tanshinones in suspension cultures of Salvia miltiorrhiza hairy roots. METHODS After suspension culture of Salvia miltiorrhiza hairy roots induced by agrobacterium rhizogenes ATCC15834 for 20 days, the ABA was added into suspension cultures, the contents of tanshinones (including tanshinone I , cryptotanshinone, dihydrotanshinon I and tanshinone II A) were detected by HPLC after 7 days. RESULTS The growth of Salvia miltiorrhiza hairy roots was inhibited by ABA. 20 micromol/L ABA treatment had no significant effect. The dry weight of Salvia miltiorrhiza hairy roots of other ABA treatments reduced to 65.2% ,71% and 56.5% of the control, respectively. Different levels of ABA could significantly increased the yields of four tanshinones in Salvia miltiorrhiza hairy roots. The yields of tanshinone I , cryptotanshinone, dihydrotanshinon I and tanshinone II A were significantly increased to 5.4, 9. 5, 1.5 and 1.8 times that of the control group after dealing with 210 micromol/ L ABA. CONCLUSION ABA can stimulate the accumulation of tanshinones in Salvia miltiorrhiza hairy roots.

Abstract
This study reported the obtainment of the full-length cDNA of Salvia miltiorrhiza hairy roots (Abbr: SmHDR, GenBank number: JX233817), via extracting Salvia miltiorrhiza hairy roots total RNA, designing specific primers according to the transcriptome data and using the RACE strategy, and then analyzed it with bioinformatics approaches. On this basis, using the real-time PCR to detect SmHDR gene expression after Ag+ induction, and testing tanshinones contents of corresponding samples by UPLC. SmHDR has 1 647 nucleotides, and an open reading frame (ORF) encoding a protein of 463 amino acid residues. The deduced protein has isoelectric point (pI) of 5.72 and a calculated molecular weight about 51.88 kD. In the secondary structure, the percentage of alpha helix, beta turn and random coil were 35.64%, 20.30% and 44.06%, respectively. Sequence alignment and phylogenetic analysis demonstrated that SmHDR had relative close relationship to the HDR of Picrorhiza kurrooa, similar to HDR from other species of plants. Real time PCR results indicated that elicitor of Ag+ stimulated the increase of mRNA expression of SmHDR. At the same time, results of ultra performance liquid chromatography (UPLC), used to examine the accumulation of diterpenoid tanshinones in hairy roots, showed that the contents of diterpenoid tanshinones in hairy roots of Salvia miltiorrhiza were increased dramatically at 12 h after treated with Ag+, and then decreased significantly. This result showed a positive correlation between the levels of mRNA expression and tanshinones accumulation in Salvia miltiorrhiza stimulated by Ag+. The content of tanshinones was gradually raised, and it had an obvious increase at 120 h. The bioinformatics analysis and gene expression indicated that SmHDR might be involved in tanshinones biosynthesis, which laid the foundation for further study of secondary metabolic regulation mechanism of tanshinones.

Abstract
Ionic liquid based, ultrasound-assisted extraction was successfully applied to the extraction of phenolcarboxylic acids, carnosic acid and rosmarinic acid, from Rosmarinus officinalis. Eight ionic liquids, with different cations and anions, were investigated in this work and [C(8)mim]Br was selected as the optimal solvent. Ultrasound extraction parameters, including soaking time, solid-liquid ratio, ultrasound power and time, and the number of extraction cycles, were discussed by single factor experiments and the main influence factors were optimized by response surface methodology. The proposed approach was demonstrated as having higher efficiency, shorter extraction time and as a new alternative for the extraction of carnosic acid and rosmarinic acid from R. officinalis compared with traditional reference extraction methods. Ionic liquids are considered to be green solvents, in the ultrasound-assisted extraction of key chemicals from medicinal plants, and show great potential.

Abstract
Plants of the genus Salvia produce various types of phenolic compounds and tanshinones which are effective for treatment of coronary heart disease. Salvia miltiorrhiza and S. castanea Diels f. tomentosa Stib are two important members of the genus. In this study, metabolic profiles and cDNA-AFLP analysis of four samples were employed to identify novel genes potentially involved in phenolic compounds and tanshinones biosynthesis, including the red roots from the two species and two tanshinone-free roots from S. miltiorrhiza. The results showed that the red roots of S. castanea Diels f. tomentosa Stib produced high contents of rosmarinic acid (21.77 mg/g) and tanshinone IIA (12.60 mg/g), but low content of salvianolic acid B (1.45 mg/g). The red roots of S. miltiorrhiza produced high content of salvianolic acid B (18.69 mg/g), while tanshinones accumulation in this sample was much less than that in S. castanea Diels f. tomentosa Stib. Tanshinones were not detected in the two tanshinone-free samples, which produced high contents of phenolic compounds. A cDNA-AFLP analysis with 128 primer pairs revealed that 2300 transcript derived fragments (TDFs) were differentially expressed among the four samples. About 323 TDFs were sequenced, of which 78 TDFs were annotated with known functions through BLASTX searching the Genbank database and 14 annotated TDFs were assigned into secondary metabolic pathways through searching the KEGGPATHWAY database. The quantitative real-time PCR analysis indicated that the expression of 9 TDFs was positively correlated with accumulation of phenolic compounds and tanshinones. These TDFs additionally showed coordinated transcriptional response with 6 previously-identified genes involved in biosynthesis of tanshinones and phenolic compounds in S. miltiorrhiza hairy roots treated with yeast extract. The sequence data in the present work not only provided us candidate genes involved in phenolic compounds and tanshinones biosynthesis but also gave us further insight into secondary metabolism in Salvia.

Abstract
The aim of this study was to use whole cell catalysts as tools for modification of selected resin acids in order to obtain value-added functional derivatives. The enzymatic bioconversion capacities of two plant species were tested towards dehydroabietic acid. Dehydroabietic acid (DHA) is an abundant resin acid in conifers, representing a natural wood protectant. It is also one of the constituents found in by-products of the kraft chemical pulping industry. DHA was fed to tobacco (Nicotiana tabacum) and Madagascar periwinkle (Catharanthus roseus) plant cell and tissue cultures and bioconversion product formation was monitored using NMR analysis. Both plant species took up DHA from culture medium, and various types of typical detoxification processes occurred in both cultures. In addition, diverse responses to DHA treatment were observed, including differences in uptake kinetics, chemical modification of added substrate and changes in overall metabolism of the cells. Interestingly, Catharanthus roseus, a host species for pharmaceutically valuable terpenoid indole alkaloids, exhibited a very different bioconversion pattern for exogenously applied DHA than tobacco, which does not possess a terpenoid indole pathway. In tobacco, DHA is readily glycosylated in the carbonyl group, whereas in periwinkle it is proposed that a cytochrome P450-catalyzed enzymatic detoxification reaction takes place before the formation of glycosylated product.
