Abstract
Early sowing can help summer crops escape drought and can mitigate the impacts of climate change on them. However, it exposes them to cold stress during initial developmental stages, which has both immediate and long-term effects on development and physiology. To understand how early night-chilling stress impacts plant development and yield, we studied the reference sunflower line XRQ under controlled, semi-controlled and field conditions. We performed high-throughput imaging of the whole plant parts and obtained physiological and transcriptomic data from leaves, hypocotyls and roots. We observed morphological reductions in early stages under field and controlled conditions, with a decrease in root development, an increase in reactive oxygen species content in leaves and changes in lipid composition in hypocotyls. A long-term increase in leaf chlorophyll suggests a stress memory mechanism that was supported by transcriptomic induction of histone coding genes. We highlighted DEGs related to cold acclimation such as chaperone, heat shock and late embryogenesis abundant proteins. We identified genes in hypocotyls involved in lipid, cutin, suberin and phenylalanine ammonia lyase biosynthesis and ROS scavenging. This comprehensive study describes new phenotyping methods and candidate genes to understand phenotypic plasticity better in response to chilling and study stress memory in sunflower.

Lang X, Zhao X, Zhao J, Ren T, Nie L, Zhao W. MicroRNA Profiling Revealed the Mechanism of Enhanced Cold Resistance by Grafting in Melon ( Cucumis melo L.). PLANTS (BASEL, SWITZERLAND) 2024; 13:1016. [PMID: 38611545 PMCID: PMC11013280 DOI: 10.3390/plants13071016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 03/23/2024] [Accepted: 04/01/2024] [Indexed: 04/14/2024]
Abstract
Grafting is widely used to improve the resistance to abiotic stresses in cucurbit plants, but the effect and molecular mechanism of grafting on cold stress are still unknown in melon. In this study, phenotypic characteristics, physiological indexes, small-RNA sequencing and expression analyses were performed on grafted plants with pumpkin rootstock (PG) and self-grafted plants (SG) to explore the mechanism of changed cold tolerance by grafting in melon. Compared with SG plants, the cold tolerance was obviously enhanced, the malondialdehyde (MDA) content was significantly decreased and the activities of antioxidant enzymes (superoxide dismutase, SOD; catalase, CAT; peroxidase, POD) were significantly increased in PG plants. Depend on differentially expressed miRNA (DEM) identification and expression pattern analyses, cme-miR156b, cme-miR156f and chr07_30026 were thought to play a key role in enhancing low-temperature resistance resulting from grafting. Subsequently, 24, 37 and 17 target genes of cme-miR156b, cme-miR156f and chr07_30026 were respectively predicted, and 21 target genes were co-regulated by cme-miR156b and cme-miR156f. Among these 57 unique target genes, the putative promoter of 13 target genes contained the low-temperature responsive (LTR) cis-acting element. The results of qRT-PCR indicated that six target genes (MELO3C002370, MELO3C009217, MELO3C018972, MELO3C016713, MELO3C012858 and MELO3C000732) displayed the opposite expression pattern to their corresponding miRNAs. Furthermore, MELO3C002370, MELO3C016713 and MELO3C012858 were significantly downregulated in cold-resistant cultivars and upregulated in cold-sensitive varieties after cold stimulus, and they acted as the key negative regulators of low-temperature response in melon. This study revealed three key miRNAs and three putative target genes involved in the cold tolerance of melon and provided a molecular basis underlying how grafting improved the low-temperature resistance of melon plants.

PLANTS (BASEL, SWITZERLAND) 2022; 11:3038. [PMID: 36432765 PMCID: PMC9696205 DOI: 10.3390/plants11223038] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 11/03/2022] [Accepted: 11/03/2022] [Indexed: 06/16/2023]
Abstract
The impacts of water supply reduction and cold storage were investigated on the peels and pulps of cv. Cogshall mangoes, regarding their phenolic compound contents. Phenolics identification was operated using HPLC-MSn for both compartments revealing an unbalanced repartition. Peels had a richer and more complex profile, counting xanthone glycoside (mangiferin), flavonoids (quercetin, kaempferol) and majorly gallotannins. Pulps presented smaller amounts of phenolics and a simpler profile majorly represented by gallotannins and gallic acid derivatives. During fruit ripening, the phenolic contents decreased in both compartments, but faster in the pulp. This behavior can be attributed to the oxidative stress observed in mango pulp during ripening. Cutting down the water supply during the fruit growth triggered an increase in phenolic contents of both the peels and pulp of mango fruits. This increase affected all compounds. Cold storage at 12 or 7 °C led to an increase in mangiferin and flavonoids contents in the fruit peel, interpreted as a stress-response reaction.

MOLECULAR PLANT PATHOLOGY 2022; 23:819-831.

Abstract
APETALA2/ethylene-responsive factor (AP2/ERF) family transcription factors are well-documented in plant responses to a wide range of biotic and abiotic stresses, but their roles in mediating elicitor-induced disease resistance remains largely unexplored. PevD1 is a Verticillium dahliae secretory effector that can induce disease resistance in cotton and tobacco plants. In our previous work, Nicotiana benthamiana ERF114 (NbERF114) was identified in a screen of genes differentially expressed in response to PevD1 infiltration. Here, we found that the ortholog of NbERF114 in Arabidopsis thaliana (ERF114) also strongly responded to PevD1 treatment and transcripts were induced by Pseudomonas syringae pv. tomato (Pst) DC3000 infection. Loss of ERF114 function caused impaired disease resistance, while overexpressing ERF114 (OE-ERF114) enhanced resistance to Pst DC3000. Moreover, ERF114 mediated PevD1-induced disease resistance. RNA-sequencing analysis revealed that the transcript level of phenylalanine ammonia-lyase1 (PAL1) and its downstream genes were significantly suppressed in erf114 mutants compared with A. thaliana Col-0. Reverse transcription-quantitative PCR (RT-qPCR) analysis further confirmed that the PAL1 mRNA level was significantly elevated in overexpressing OE-ERF114 plants but reduced in erf114 mutants compared with Col-0. Chromatin immunoprecipitation-qPCR (ChIP-qPCR) and electrophoretic mobility shift assay verified that ERF114 directly bound to the promoter of PAL1. The gene expression profiles of ERF114 and PAL1 in oestradiol-inducible transgenic plants confirmed ERF114 could activate PAL1 transcriptional expression. Further investigation revealed that ERF114 positively modulated PevD1-induced lignin and salicylic acid accumulation, probably by activating PAL1 transcription.

Abstract
Boosting cold stress tolerance in crop plants can minimize stress-mediated yield losses. Asian rice (Oryza sativa L.), one of the most consumed cereal crops, originated from subtropical regions and is generally sensitive to low temperature environments. Within the two subspecies of rice, JAPONICA, and INDICA, the cold tolerance potential of its accessions is highly variable and depends on their genetic background. Yet, cold stress tolerance response mechanisms are complex and not well understood. This study utilized 370 accessions from the Rice Diversity Panel 1 (RDP1) to investigate and correlate four cold stress tolerance response phenotypes: membrane damage, seedling survivability, and catalase and anthocyanin antioxidative activity. Most JAPONICA accessions, and admixed accessions within JAPONICA, had lower membrane damage, higher antioxidative activity, and overall, higher seedling survivability compared to INDICA accessions. Genome-wide association study (GWAS) mapping was done using the four traits to find novel quantitative trait loci (QTL), and to validate and fine-map previously identified QTL. A total of 20 QTL associated to two or more traits were uncovered by our study. Gene Ontology (GO) term enrichment analyses satisfying four layers of filtering retrieved three potential pathways: signal transduction, maintenance of plasma membrane and cell wall integrity, and nucleic acids metabolism as general mechanisms of cold stress tolerance responses involving antioxidant activity.

Abstract
Background Non-heading Chinese cabbage (Brassica rapa ssp. chinensis) is an important leaf vegetable grown worldwide. However, there has currently been not enough transcriptome and small RNA combined sequencing analysis of cold tolerance, which hinders further functional genomics research. Results In this study, 63.43 Gb of clean data was obtained from the transcriptome analysis. The clean data of each sample reached 6.99 Gb, and the basic percentage of Q30 was 93.68% and above. The clean reads of each sample were sequence aligned with the designated reference genome (Brassica rapa, IVFCAASv1), and the efficiency of the alignment varied from 81.54 to 87.24%. According to the comparison results, 1,860 new genes were discovered in Pak-choi, of which 1,613 were functionally annotated. Among them, 13 common differentially expressed genes were detected in all materials, including seven upregulated and six downregulated. At the same time, we used quantitative real-time PCR to confirm the changes of these gene expression levels. In addition, we sequenced miRNA of the same material. Our findings revealed a total of 34,182,333 small RNA reads, 88,604,604 kinds of small RNAs, among which the most common size was 24 nt. In all materials, the number of common differential miRNAs is eight. According to the corresponding relationship between miRNA and its target genes, we carried out Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis on the set of target genes on each group of differentially expressed miRNAs. Through the analysis, it is found that the distributions of candidate target genes in different materials are different. We not only used transcriptome sequencing and small RNA sequencing but also used experiments to prove the expression levels of differentially expressed genes that were obtained by sequencing. Sequencing combined with experiments proved the mechanism of some differential gene expression levels after low-temperature treatment. Conclusion In all, this study provides a resource for genetic and genomic research under abiotic stress in Pak-choi.

Abstract
BACKGROUND Sugarcane (Saccharum officinarum) is one of the most valuable feedstocks for sugar production. In addition to the production of industrial raw materials such as alcohol, papermaking, the fiber of livestock feed, respectively, sugarcane can produce bioactive compounds such as anthocyanins. Elucidation of the anthocyanin biosynthesis pathway is critical for the molecular breeding of sugarcane varieties with favorable traits. We aimed to identify candidate genes involved in anthocyanin biosynthesis by transcriptomic and metabolomic analyses. RESULTS Three varieties of sugarcane displaying different colors were used in this study: FN15 (greed rind), ROC22 (red rind), and Badila (purple rind). Sample materials were subjected to metabolomic analysis using UPLC-Q-TOF/MS and RNA-seq analysis. The metabolomic profiling results showed Cyanidin, Cyanidin (6'-malonylglucoside), Cyanidin O-glucoside, and Peonidin O-glucoside were the main components responsible for the rind color. Then, through RNA-seq analysis, we identified a total of 3137, 3302, 3014 differentially expressed genes (DEGs) between the rind and pith tissues for the corresponding varieties Badila rind, ROC22, and FN15. We then compared the expression levels of genes among the rind tissues from the three varieties. We identified 2901, 2821, and 3071 DEGs between Badila rind vs. ROC22 rind, Badila rind vs. FN15 rind, ROC22 rind vs. FN15 rind, respectively. We identified two enriched pathways, including phenylpropanoid biosynthesis and flavonoid biosynthesis. Sequencing similarity search identified a total of 50 unigenes belonging to 15 enzyme families as putative genes involved in anthocyanin biosynthesis in sugarcane rind. Seven of them were identified as candidate genes related to anthocyanin biosynthesis in the rind of sugarcane through co-localization analysis with the anthocyanin content in sugarcane. In total, 25 unigenes were selected and subjected to RT-qPCR analysis, and qRT-PCR results were consistent with those obtained with the RNA-Seq experiments. CONCLUSIONS We proposed a pathway for anthocyanin biosynthesis in sugarcane rind. This is the first report on the biosynthesis of anthocyanin in sugarcane using the combined transcriptomic and metabolomic methods. The results obtained from this study will lay the foundation for breeding purple pith sugarcane varieties with high anthocyanin contents.

Abstract
Sweetpotato [Ipomoea batatas (L.) Lam] is an economically important crop for fresh and processed consumption and is widely cultivated worldwide, especially in China. Various sweetpotato cultivars with different storage root colors are presently available. The purple-fleshed sweetpotato obtains its color from anthocyanin accumulation in the storage roots, which is beneficial for both plant and human health. To date, the molecular mechanism of this anthocyanin accumulation has not been studied in detail. In our study, three cDNA libraries generated from 'Xuzi8' with dark-purple flesh, 'Xuzi6' with light-purple flesh, and 'Xu28' with white flesh were sequenced utilizing an Illumina HiSeq™ 2500 platform. Corresponding totals of 28,093,466, 29,239,729 and 27,217,440 raw reads were obtained from the three libraries and assembled into 137,625 unigenes with an average length of 481 bp. Moreover, 79,203 unigenes (57.55%) were found to be annotated in several public databases, and 1285 unigenes were differentially expressed among the Xu28 vs Xuzi8, Xu28 vs Xuzi6, and Xuzi6 vs Xuzi8 libraries. After functional category enrichment analysis of differential expression genes (DEGs), 25 genes were selected as the candidate genes related to anthocyanin accumulation. Furthermore, the expression patterns of some selected DEGs were verified by quantitative real-time PCR (qRT-PCR), and the correlation between expression levels of relevant genes involved in anthocyanin biosynthesis and anthocyanin content was determined. Taken together, the results compose a transcriptomic analysis to investigate the differences in purple flesh formation in the storage roots among different sweetpotato varieties, with the notable outcome that several key genes can now be closely linked to anthocyanin biosynthesis.

Abstract
Background Phytochromes are plant photoreceptors that have long been associated with photomorphogenesis in plants; however, more recently, their crucial role in the regulation of variety of abiotic stresses has been explored. Chilling stress is one of the abiotic factors that severely affect growth, development, and productivity of crops. In the present work, we have analyzed and compared physiological, biochemical, and molecular responses in two contrasting phytochrome mutants of tomato, namely aurea (aur) and high pigment1 (hp1), along with wild-type cultivar Micro-Tom (MT) under chilling stress. In tomato, aur is phytochrome-deficient mutant while hp1 is a phytochrome-sensitive mutant. The genotype-specific physiological, biochemical, and molecular responses under chilling stress in tomato mutants strongly validated phytochrome-mediated regulation of abiotic stress. Results Here, we demonstrate that phytochrome-sensitive mutant hp1 show improved performance compared to phytochrome-deficient mutant aur and wild-type MT plants under chilling stress. Interestingly, we noticed significant increase in several photosynthetic-related parameters in hp1 under chilling stress that include photosynthetic rate, stomatal conductance, stomatal aperture, transpiration rate, chlorophyll a and carotenoids. Whereas most parameters were negatively affected in aur and MT except a slight increase in carotenoids in MT plants under chilling stress. Further, we found that PSII quantum efficiency (Fv/Fm), PSII operating efficiency (Fq′/Fm′), and non-photochemical quenching (NPQ) were all positively regulated in hp1, which demonstrate enhanced photosynthetic performance of hp1 under stress. On the other hand, Fv/Fm and Fq′/Fm′ were decreased significantly in aur and wild-type plants. In addition, NPQ was not affected in MT but declined in aur mutant after chilling stress. Noticeably, the transcript analysis show that PHY genes which were previously reported to act as molecular switches in response to several abiotic stresses were mainly induced in hp1 and repressed in aur and MT in response to stress. As expected, we also found reduced levels of malondialdehyde (MDA), enhanced activities of antioxidant enzymes, and higher accumulation of protecting osmolytes (soluble sugars, proline, glycine betaine) which further elaborate the underlying tolerance mechanism of hp1 genotype under chilling stress. Conclusion Our findings clearly demonstrate that phytochrome-sensitive and phytochrome-deficient tomato mutants respond differently under chilling stress thereby regulating physiological, biochemical, and molecular responses and thus establish a strong link between phytochromes and their role in stress tolerance.

Abstract
Plants are phytochemical hubs containing antioxidants, essential for normal plant functioning and adaptation to environmental cues and delivering beneficial properties for human health. Therefore, knowledge on the antioxidant potential of different plant species and their nutraceutical and pharmaceutical properties is of utmost importance. Exploring this scientific research field provides fundamental clues on (1) plant stress responses and their adaptive evolution to harsh environmental conditions and (2) (new) natural antioxidants with a functional versatility to prevent and treat human pathologies. These natural antioxidants can be valorized via plant-derived foods and products. Cuba contains an enormously rich plant biodiversity harboring a great antioxidant potential. Besides opening new avenues for the implementation of sustainable agroecological practices in crop production, it will also contribute to new strategies to preserve plant biodiversity and simultaneously improve nature management policies in Cuba. This review provides an overview on the beneficial properties of antioxidants for plant protection and human health and is directed to the valorization of these plant antioxidants, emphasizing the need for biodiversity conservation.

Abstract
The expression levels of many genes and the related proteins change and regulate physiological and metabolic processes that help the plant survive harsh environmental conditions under cold stress. Damage due to cold and freezing conditions often causes dynamic loss of loquat fruits in cultivated parts of northern China. To illustrate the mechanism of cold tolerance in the loquat, we combined the transcriptomic analysis with isobaric tags for relative and absolute quantification (iTRAQ) and RNA sequencing (RNA-Seq) data from loquat leaves under 4 °C treatment. The results showed 122,081 genes and 1210 differentially expressed genes (DEGs), while only 4582 proteins and 300 differential proteins (DEPs) were identified. Functional annotation and Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway analysis indicated that metabolic pathways and biosynthesis of secondary metabolites were the two most common pathways in transcriptional and translational processes in this study. Comparison analysis of the transcriptomic and proteomic profiles, only 27 of 3620 genes were found to be shared both in DEGs and DEPs. Further validation with Real-Time Quantitative RT-PCR analysis showed that the genes expression of NADP-dependent D-sorbitol-6-phosphate dehydrogenase, anthocyanin synthase and phenylalanine ammonia-lyase were consistent with the pattern of transcriptome profile, which suggested that these three genes might play vital roles in cold tolerance in loquat.

Abstract
The accumulation of flavonoids is activated by various abiotic stresses, and the induction of reactive oxygen species (ROS) especially hydrogen peroxide (H2O2) is a general response to abiotic stress in plants. However, the direct link between flavonoids and H2O2 and underlying mechanism remain elusive. In this study, we found that the concentrations of anthocyanin and flavonoids were significantly induced by H2O2 treatment. Furthermore, we found that the transcript level of ZINC FINGER of ARABIDOPSIS THALIANA 6 (ZAT6) was significantly activated after exogenous H2O2 treatment, and modulation of AtZAT6 expression positively affected the concentrations of both anthocyanin and total flavonoids. Notably, exogenous H2O2-induced anthocyanin synthesis was largely alleviated in AtZAT6 knockdown plants, but showed higher level in AtZAT6 overexpressing plants. AtZAT6 directly activated the expressions of TT5, TT7, TT3, TT18, MYB12, and MYB111 through binding to their promoters with TACAAT elements of these genes, and the activation of MYB12 and MYB111 up-regulated the expressions of TT4 and TT6. Taken together, this study indicates that AtZAT6 plays important role in H2O2-activated anthocyanin synthesis, via directly binding to the promoters of several genes that involved in anthocyanin synthesis.

Abstract
Plants face a combination of different abiotic stresses under field conditions which are lethal to plant growth and production. Simultaneous occurrence of chilling and drought stresses in plants due to the drastic and rapid global climate changes, can alter the morphological, physiological and molecular responses. Both these stresses adversely affect the plant growth and yields due to physical damages, physiological and biochemical disruptions, and molecular changes. In general, the co-occurrence of chilling and drought combination is even worse for crop production rather than an individual stress condition. Plants attain various common and different physiological and molecular protective approaches for tolerance under chilling and drought stresses. Nevertheless, plant responses to a combination of chilling and drought stresses are unique from those to individual stress. In the present review, we summarized the recent evidence on plant responses to chilling and drought stresses on shared as well as unique basis and tried to find a common thread potentially underlying these responses. We addressed the possible cross talk between plant responses to these stresses and discussed the potential management strategies for regulating the mechanisms of plant tolerance to drought and/or chilling stresses. To date, various novel approaches have been tested in minimizing the negative effects of combine stresses. Despite of the main improvements there is still a big room for improvement in combination of drought and chilling tolerance. Thus, future researches particularly using biotechnological and molecular approaches should be carried out to develop genetically engineered plants with enhanced tolerance against these stress factors.

Abstract
Sugarcane (Saccharum sp.) is predominantly grown in both tropics and subtropics in India, and the subtropics alone contribute more than half of sugarcane production. Sugarcane active growth period in subtropics is restricted to 8-9 months mainly due to winter's low temperature stress prevailing during November to February every year. Being a commercial crop, tolerance to low temperature is important in sugarcane improvement programs. Development of cold tolerant sugarcane varieties require a deep knowledge on molecular mechanism naturally adapted by cold tolerant genotypes during low temperature stress. To understand gene regulation under low temperature stress, control and stressed (10 °C, 24 h) leaf samples of cold tolerant S. spontaneum IND 00-1037 collected from high altitude region in Arunachal Pradesh were used for transcriptome analysis using the Illumina NextSeq 500 platform with paired-end sequencing method. Raw reads of 5.1 GB (control) and 5.3 GB (stressed) obtained were assembled using trinity and annotated with UNIPROT, KEGG, GO, COG and SUCEST databases, and transcriptome was validated using qRT-PCR. The differential gene expression (DGE) analysis showed that 2583 genes were upregulated and 3302 genes were down-regulated upon low temperature stress. A total of 170 cold responsive transcriptional factors belonging to 30 families were differentially regulated. CBF6 (C-binding factor), a DNA binding transcriptional activation protein associated with cold acclimation and freezing tolerance was differentially upregulated. Many low temperature responsive genes involved in various metabolic pathways, viz. cold sensing through membrane fluidity, calcium and lipid signaling genes, MAP kinases, phytohormone signaling and biosynthetic genes, antioxidative enzymes, membrane and cellular stabilizing genes, genes involved in biosynthesis of polyunsaturated fatty acids, chaperones, LEA proteins, soluble sugars, osmoprotectants, lignin and pectin biosynthetic genes were also differentially upregulated. Potential cold responsive genes and transcriptional factors involved in cold tolerance mechanism in cold tolerant S. spontaneum IND 00-1037 were identified. Together, this study provides insights into the cold tolerance to low temperature stress in S. spontaneum, thus opening applications in the genetic improvement of cold stress tolerance in sugarcane.

Abstract
Cedar-apple rust (Gymnosporangium yamadai Miyabe) is a fungal disease that causes substantial injury to apple trees and results in fruit with reduced size and quality and a lower commercial value. The molecular mechanisms underlying the primary and secondary metabolic effects of rust spots on the leaves of Malus apple cultivars are poorly understood. Using HPLC, we found that the contents of flavonoid compounds, especially anthocyanin and catechin, were significantly increased in rust-infected symptomatic tissue (RIT). The expression levels of structural genes and MYB transcription factors related to flavonoid biosynthesis were one- to seven-fold higher in the RIT. Among these genes, CHS, DFR, ANS, FLS and MYB10 showed more than a 10-fold increase, suggesting that these genes were expressed at significantly higher levels in the RIT. Hormone concentration assays showed that the levels of abscisic acid (ABA), ethylene (ETH), jasmonate (JA) and salicylic acid (SA) were higher in the RIT and were consistent with the expression levels of McNCED, McACS, McLOX and McNPR1, respectively. Our study explored the complicated crosstalk of the signal transduction pathways of ABA, ETH, JA and SA; the primary metabolism of glucose, sucrose, fructose and sorbitol; and the secondary metabolism of flavonoids involved in the rust resistance of Malus crabapple leaves.

Abstract
BACKGROUND Tea (Camellia sinensis L.), contains high levels of secondary metabolic products with both commercial and medicinal value. At present, most cultivated tea plant have green leaves; although tea plants with purple leaves exist, their supply is inadequate. During leaf growth and maturation, the content of secondary metabolic compounds decreases, resulting in higher content in tender purple leaves (TPL), and lower content in mature green leaves (MGL). The aim of this study was to analyze the differential expression of genes in these two tissues, with a cDNA-AFLP (amplified fragment length polymorphism) approach and biochemical analysis. RESULTS Compared to MGL samples, TPL samples had higher content of anthocyanin, total polyphenols and total catechins, a higher carotenoid-to-chlorophyll ratio and lower content of soluble sugars (glucose, fructose and sucrose). TPL samples showed a lower photosynthetic ability, demonstrated by a lower CO2 assimilation and carbohydrate accumulation rate. Using cDNA-AFLP with 256 primer combinations, differential transcript profiling generated 148 matched transcript-derived fragments (TDFs). Among these TDFs, 77 genes were upregulated and 71 were downregulated. These were grouped into 11 functional categories which are important for final tea quality parameters. CONCLUSIONS Our data presented the first effort to elucidate the molecular basis of differential accumulation of key metabolites during tea leaf maturation. Our findings also provided a theoretical molecular explanation for the color change during leaf growth.

Abstract
Kidney bean (Phaseolus vulgaris L.) is an important dietary legume crop cultivated and consumed worldwide. A purple cultivar (Zi Bawang) and a green cultivar (Chun Qiu), the main difference of which is in the pod skin color, were selected for the study. Malvidin 3, 5-diglucoside is identified as the major anthocyanin in the pod skin of Zi Bawang by HPLC-ESI-MS/MS. Three regulatory genes PvMYB1, PvMYB2, PvTT8-1 and most structural genes are dramatically up-regulated in purple pod skin compared to those in other materials. Significantly decreased expression levels of all regulatory genes and most biosynthetic genes are also detected in the purple skin of pods covered with bags compared to non-covered ones. All the results suggest that PvMYB1, PvMYB2 and PvTT8-1 might play a critical role in transcriptional activation of most anthocyanin biosynthetic genes in purple kidney bean pod.

Li Q, Wang J, Sun HY, Shang X. Flower color patterning in pansy (Viola × wittrockiana Gams.) is caused by the differential expression of three genes from the anthocyanin pathway in acyanic and cyanic flower areas. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2014; 84:134-141. [PMID: 25270164 DOI: 10.1016/j.plaphy.2014.09.012] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2014] [Accepted: 09/23/2014] [Indexed: 05/20/2023]
Abstract
The petals of pansy (Viola × wittrockiana Gams.) 'Mengdie' exhibit a cyanic blotched pigmentation pattern. The accumulation of anthocyanins, cyanidin and delphinidin, was detected in the upper epidermal cells of the cyanic blotches. In order to elucidate the mechanism by which cyanic blotches are formed in pansy petal, the expression level of genes involved in anthocyanin synthesis was measured and compared between cyanic blotches and acyanic areas of the flower. The use of primers in conserved regions allowed the successful isolation of six cDNA clones encoding putative anthocyanin enzymes from pansy petals. The clones isolated encoded chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), flavonoid 3'-hydroxylase (F3'H), dihydroflavonol 4-reductase (DFR) and anthocyanidin synthase (ANS). The transcription patterns of seven genes (VwCHS, VwCHI, VwF3H, VwF3'H, VwDFR, VwF3'5'H, and VwANS) in cyanic blotches and acyanic areas of the petals at seven stages of flower development were determined by real-time quantitative PCR. Transcription of VwF3'5'H, VwDFR and VwANS was significantly increased in cyanic blotches at stages III-V of flower development, implicating these genes in the pigmentation of Viola × wittrockiana Gams. petals.

Abstract
In this study, the changes caused by chilling stress on some physiological parameters of pepino (Solanum muricatum Ait.) plant and the effects of ascorbic acid (100 mM) applied exogenously on these changes were examined. For this purpose, the photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophylls and carotenoids), ascorbic acid, total phenolic compounds, malondialdehyde and proline contents in leaves of pepino taken on 5th and 10th days were determined. As a result of chilling stress, it was found that while the photosynthetic pigments and proline contents decreased in pepino leaves, the ascorbic acid, total phenolic compounds and malondialdehyde contents increased. In plants which were subjected to pre-treatment of ascorbic acid on the 10th day of stress, ascorbic acid and proline contents increased while a decrease was observed in malondialdehyde content, compared to stress group without pre-treated. This study may be important for explaining resistance induced by treatment of exogenous ascorbic acid in pepino exposed to chilling stress.

Genome-wide transcriptome analysis of two contrasting Brassica rapa doubled haploid lines under cold-stresses using Br135K oligomeric chip. PLoS One 2014; 9:e106069. [PMID: 25167163 PMCID: PMC4148347 DOI: 10.1371/journal.pone.0106069] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2014] [Accepted: 07/27/2014] [Indexed: 12/02/2022] Open
Abstract
Genome wide transcription analysis in response to stresses is important to provide a basis of effective engineering strategies to improve stress tolerance in crop plants. We assembled a Brassica rapa oligomeric microarray (Br135K microarray) using sequence information from 41,173 unigenes and analyzed the transcription profiles of two contrasting doubled haploid (DH) lines, Chiifu and Kenshin, under cold-treatments. The two DH lines showed great differences in electrolyte leakage below −4°C, but similar patterns from 4°C to −2°C. Cold-treatments induced 885 and 858 genes in Chiifu and Kenshin, respectively. Overall, 134, and 56 genes showed an intrinsic difference in expression in Chiifu and Kenshin, respectively. Among 5,349 genes that showed no hit found (NHF) in public databases, 61 and 24 were specifically expressed in Chiifu and Kenshin, respectively. Many transcription factor genes (TFs) also showed various characteristics of expression. BrMYB12, BrMYBL2, BrbHLHs, BrbHLH038, a C2H2, a WRKY, BrDREB19 and a integrase-type TF were induced in a Chiifu-specific fashion, while a bHLH (Bra001826/AT3G21330), bHLH, cycling Dof factor and two Dof type TFs were Kenshin specific. Similar to previous studies, a large number of genes were differently induced or regulated among the two genotypes, but many genes, including NHFs, were specifically or intrinsically expressed with genotype specificity. Expression patterns of known-cold responsive genes in plants resulted in discrepancy to membrane leakage in the two DH lines, indicating that timing of gene expression is more important to conferring freezing tolerance rather than expression levels. Otherwise, the tolerance will be related to the levels of transcripts before cold-treatment or regulated by other mechanisms. Overall, these results indicate common signaling pathways and various transcriptional regulatory mechanisms are working together during cold-treatment of B. rapa. Our newly developed Br135K oligomeric microarray will be useful for transcriptome profiling, and will deliver valuable insight into cold stresses in B. rapa.
