PHYSIOLOGIA PLANTARUM 2024; 176:e14335. [PMID: 38705728 DOI: 10.1111/ppl.14335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 04/18/2024] [Accepted: 04/23/2024] [Indexed: 05/07/2024]
Abstract
Sound vibrations (SV) are known to influence molecular and physiological processes that can improve crop performance and yield. In this study, the effects of three audible frequencies (100, 500 and 1000 Hz) at constant amplitude (90 dB) on tomato Micro-Tom physiological responses were evaluated 1 and 3 days post-treatment. Moreover, the potential use of SV treatment as priming agent for improved Micro-Tom resistance to Pseudomonas syringae pv. tomato DC3000 was tested by microarray. Results showed that the SV-induced physiological changes were frequency- and time-dependent, with the largest changes registered at 1000 Hz at day 3. SV treatments tended to alter the foliar content of photosynthetic pigments, soluble proteins, sugars, phenolic composition, and the enzymatic activity of polyphenol oxidase, peroxidase, superoxide dismutase and catalase. Microarray data revealed that 1000 Hz treatment is effective in eliciting transcriptional reprogramming in tomato plants grown under normal conditions, but particularly after the infection with Pst DC3000. Broadly, in plants challenged with Pst DC3000, the 1000 Hz pretreatment provoked the up-regulation of unique differentially expressed genes (DEGs) involved in cell wall reinforcement, phenylpropanoid pathway and defensive proteins. In addition, in those plants, DEGs associated with enhancing plant basal immunity, such as proteinase inhibitors, pathogenesis-related proteins, and carbonic anhydrase 3, were notably up-regulated in comparison with non-SV pretreated, infected plants. These findings provide new insights into the modulation of Pst DC3000-tomato interaction by sound and open up prospects for further development of strategies for plant disease management through the reinforcement of defense mechanisms in Micro-Tom plants.

Abstract
Morus alba L. is used for a range of therapeutic purposes in Asian traditional medicine, and its extracts are reported to be effective against lipidemia, diabetes, and obesity, as well as being hepatoprotective and tyrosinase-inhibitory. They are also included in cosmetic products as anti-aging and skin-whitening agents. Stilbenes, the major bioactive compounds found in M. alba, have received renewed attention recently because of their putative activity against COVID-19. In this study M. alba plants were established in vitro, and the effect of elicitation on plant growth and stilbene accumulation, specifically oxyresveratrol and trans-resveratrol, was investigated. Different concentrations of the elicitors including methyl jasmonate and cyclodextrins were applied, and stilbene levels were determined in leaves, roots, and the culture medium. Elicitation of the M. alba plants with 5 mM cyclodextrins, alone or in combination with 10 µM methyl jasmonate, significantly increased the total phenolic content in the culture medium and leaves after 7 days of treatment. The higher total phenolic content in the roots of control plants and those treated only with methyl jasmonate indicated that cyclodextrins promoted metabolite release to the culture medium. Notably, the cyclodextrin-treated plants with the highest levels of oxy- and trans-resveratrol also had the highest total phenolic content and antioxidant capacity. These results indicate that elicited M. alba in vitro plants constitute a promising alternative source of bioactive stilbenes to supply pharmaceutical and cosmeceutical industries.

PLANTS (BASEL, SWITZERLAND) 2022; 11:2782. [PMID: 36297806 PMCID: PMC9609435 DOI: 10.3390/plants11202782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 10/12/2022] [Accepted: 10/18/2022] [Indexed: 06/16/2023]
Abstract
In this work, Solanum lycopersicum cv. Micro-Tom suspension-cultured cells were used to analyze the effect of different elicitors including β-cyclodextrins (CD), methyl jasmonate (MJ), β-glucan (Glu) and 3-hexenol (Hex) separately and the combined treatments of CD + MJ, CD + glu and CD + Hex on triterpene compound production after 24, 72 and 96 h. Moreover, we studied the changes induced by elicitors in the expression of key biosynthetic genes to elucidate the regulation of the triterpene biosynthetic pathway. The relative abundance of the triterpene compounds identified in the extracellular medium after elicitation (squalene, fucosterol, avenasterol, β-sitosterol, cycloartenol and taraxasterol) was determined by gas chromatography coupled to mass spectrometry, and the expression level of genes in treated-cells was analyzed by real-time quantitative polymerase chain reaction (qRT-PCR). Results showed that, in CD-treated cells (CD, CD + MJ, CD + Glu, CD + Hex), specialized metabolites were accumulated mainly in the extracellular medium after 72 h of elicitation. Moreover, qRT-PCR analysis revealed that the highest triterpene levels in CD-treated cells (CD, CD + MJ, CD + Glu, CD + Hex) were highly correlated with the expression of cycloartenol synthase, 3-hydroxy-3-methylglutaryl-CoA reductase and squalene epoxidase genes at 24 h of treatment, whereas the expression of sterol methyltransferase was increased at 72 h. According to our findings, CD acts as a true elicitor of triterpene biosynthesis and can promote the release of bioactive compounds from the tomato cells into the extracellular medium. The results obtained provide new insights into the regulation of the triterpene metabolic pathway, which might be useful for implementing metabolic engineering techniques in tomato.

Differential Response of Phenol Metabolism Associated with Antioxidative Network in Elicited Grapevine Suspension Cultured Cells under Saline Conditions. Antioxidants (Basel) 2022; 11:antiox11020388.

Abstract
Highly productive trans-resveratrol (t-R) grapevine suspension cultured cells (SCC) and two effective elicitors, methyl jasmonate (MJ) and randomly methylated β-cyclodextrins (CDs), were used to analyze the extent to which salt treatments alter the production of bioactive phenolic compounds. The expression/activity profile of the enzymes involved in phenol metabolism and antioxidant networks were also studied. A marked extracellular accumulation of phenolic compounds, especially t-R, was found in SCC elicited with CDs and/or MJ under saline conditions. However, the treatments with MJ alone and all those combined with salt favored the intracellular accumulation of catechin and ferulic acid. The salt-induced accumulation of phenolics was correlated with the higher total antioxidant capacity values found in cells, suggesting that cellular redox homeostasis under saline conditions was largely maintained by increasing phenolic compound production. These higher levels of phenolics found in elicited cells under saline conditions fit well with the highest activity of phenylalanine ammonia-lyase. Moreover, antioxidant enzyme activities were boosted in treatments with MJ and/or in those combined with salt and decreased in those treated with CDs. These results suggest a differential response of the antioxidative network to the presence of elicitors under saline conditions.

Abstract
The influence of preparation material residues in wastewater and soil on plants has been paid more and more attention by researchers. Secondary metabolites play an important role in the application of plants. It was found that nanomaterials can increase the content of plant secondary metabolites in addition to their role in pharmaceutical preparations. For example, 800 mg/kg copper oxide nanoparticles (NPs) increased the content of p-coumaric acid in cucumber by 225 times. Nanoparticles can cause oxidative stress in plants, increase signal molecule, and upregulate the synthase gene expression, increasing the content of secondary metabolites. The increase of components such as polyphenols and total flavonoids may be related to oxidative stress. This paper reviews the application and mechanism of metal nanomaterials (Ag-NP, ZnO-NP, CeO2-NP, Cds-NP, Mn-NP, CuO-NP) in promoting the synthesis of secondary metabolites from plants. In addition, the effects of some other preparative materials (cyclodextrins and immobilized molds) on plant secondary metabolites are also involved. Finally, possible future research is discussed.

Abstract
Triterpenic compounds stand as a widely investigated class of natural compounds due to their remarkable therapeutic potential. However, their use is currently being hampered by their low solubility and, subsequently, bioavailability. In order to overcome this drawback and increase the therapeutic use of triterpenes, cyclodextrins have been introduced as water solubility enhancers; cyclodextrins are starch derivatives that possess hydrophobic internal cavities that can incorporate lipophilic molecules and exterior surfaces that can be subjected to various derivatizations in order to improve their biological behavior. This review aims to summarize the most recent achievements in terms of triterpene:cyclodextrin inclusion complexes and bioconjugates, emphasizing their practical applications including the development of new isolation and bioproduction protocols, the elucidation of their underlying mechanism of action, the optimization of triterpenes’ therapeutic effects and the development of new topical formulations.

Abstract
Small secreted proteins (SSPs) are less than 250 amino acids in length and are actively transported out of cells through conventional protein secretion pathways or unconventional protein secretion pathways. In plants, SSPs have been found to play important roles in various processes, including plant growth and development, plant response to abiotic and biotic stresses, and beneficial plant-microbe interactions. Over the past 10 years, substantial progress has been made in the identification and functional characterization of SSPs in several plant species relevant to agriculture, bioenergy, and horticulture. Yet, there are potentially a lot of SSPs that have not been discovered in plant genomes, which is largely due to limitations of existing computational algorithms. Recent advances in genomics, transcriptomics, and proteomics research, as well as the development of new computational algorithms based on machine learning, provide unprecedented capabilities for genome-wide discovery of novel SSPs in plants. In this review, we summarize known SSPs and their functions in various plant species. Then we provide an update on the computational and experimental approaches that can be used to discover new SSPs. Finally, we discuss strategies for elucidating the biological functions of SSPs in plants.

Abstract
The commercialisation of valuable plant triterpenoids faces major challenges, including low abundance in natural hosts and costly downstream purification procedures. Endeavours to produce these compounds at industrial scale using microbial systems are gaining attention. Here, we report on a strategy to enrich the biomass of the biotechnologically-relevant Chlamydomonas reinhardtii strain UVM4 with valuable triterpenes, such as squalene and (S)-2,3-epoxysqualene. C. reinhardtii UVM4 was subjected to the elicitor compounds methyl jasmonate (MeJA) and methyl-β-cyclodextrine (MβCD) to increase triterpene yields. MeJA treatment triggered oxidative stress, arrested growth, and altered the photosynthetic activity of the cells, while increasing squalene, (S)-2,3-epoxysqualene, and cycloartenol contents. Applying MβCD to cultures of C. reinhardtii lead to the sequestration of the two main sterols (ergosterol and 7-dehydroporiferasterol) into the growth medium and the intracellular accumulation of the intermediate cycloartenol, without compromising cell growth. When MβCD was applied in combination with MeJA, it counteracted the negative effects of MeJA on cell growth and physiology, but no synergistic effect on triterpene yield was observed. Together, our findings provide strategies for the triterpene enrichment of microalgal biomass and medium.

Abstract
Modern lifestyle factors, such as physical inactivity, obesity, smoking, and exposure to environmental pollution, induce excessive generation of free radicals and reactive oxygen species (ROS) in the body. These by-products of oxygen metabolism play a key role in the development of various human diseases such as cancer, diabetes, heart failure, brain damage, muscle problems, premature aging, eye injuries, and a weakened immune system. Synthetic and natural antioxidants, which act as free radical scavengers, are widely used in the food and beverage industries. The toxicity and carcinogenic effects of some synthetic antioxidants have generated interest in natural alternatives, especially plant-derived polyphenols (e.g., phenolic acids, flavonoids, stilbenes, tannins, coumarins, lignins, lignans, quinines, curcuminoids, chalcones, and essential oil terpenoids). This review focuses on the well-known phenolic antioxidant rosmarinic acid (RA), an ester of caffeic acid and (R)-(+)-3-(3,4-dihydroxyphenyl) lactic acid, describing its wide distribution in thirty-nine plant families and the potential productivity of plant sources. A botanical and phytochemical description is provided of a new rich source of RA, Satureja khuzistanica Jamzad (Lamiaceae). Recently reported approaches to the biotechnological production of RA are summarized, highlighting the establishment of cell suspension cultures of S. khuzistanica as an RA chemical biofactory.

Abstract
Plant cell suspension culture (PCSC) has emerged as a viable technology to produce plant specialized metabolites (PSM). While Taxol® and ginsenoside are two examples of successfully commercialized PCSC-derived PSM, widespread utilization of the PCSC platform has yet to be realized primarily due to a lack of understanding of the molecular genetics of PSM biosynthesis. Recent advances in computational, molecular and synthetic biology tools provide the opportunity to rapidly characterize and harness the specialized metabolic potential of plants. Here, we discuss the prospects of integrating computational modeling, artificial intelligence, and precision genome editing (CRISPR/Cas and its variants) toolboxes to discover the genetic regulators of PSM. We also explore how synthetic biology can be applied to develop metabolically optimized PSM-producing native and heterologous PCSC systems. Taken together, this review provides an interdisciplinary approach to realize and link the potential of next-generation computational and molecular tools to convert PCSC into commercially viable PSM-producing biofactories.

Abstract
This work evaluates the effect of the pathogens Colletotrichum siamense and C. gloeosporioides on the response of soursop fruits. The bioactive compounds (total phenols, flavonoids, anthraquinones, coumarins, steroids, terpenoids, alkaloids, and saponins) were evaluated qualitatively in soursop pulp. Positive phytochemicals and antioxidant activity (DPPH•, ABTS•+, and FRAP) were quantified at day zero, one, three, and five. Fruits treated with C. gloeosporioides showed higher disease severity (P<0.05). Early fruit response (day one) was observed with both pathogens, increased the concentration of saponins and repressed the production of quercetin 3-O-glucoside (P<0.05). Likewise, C. siamense decreased total soluble phenols and flavonoids and increased antiradical activity DPPH•. Besides, C. gloeosporioides decreased the levels of kaempferol 3-O-rutinoside and ferulic acid (P<0.05). Regarding the late response (day three), both pathogens decreased the concentration of saponins and increased flavonoids and phytosterols (P<0.05). Nevertheless, C. siamense increased the levels of total soluble phenols, p-coumaric acid, kaempferol, and antiradical activity FRAP (P<0.05). Also, C. gloeosporioides repressed the production of quercetin 3-O-glucoside at day five (P<0.05). Soursop fruits had a response to the attack of Colletotrichum during ripening at physicochemical and oxidative levels, which is associated with the production of compounds related to the development inhibition of pathogens. Even so, soursop fruits showed higher susceptibility to C. gloeosporioides and higher sensitivity to the attack of C. siamense.

Abstract
Terbinafine induced a significant increase of squalene production. Terbinafine increased the expression levels of squalene synthase. Cyclodextrins did not work as elicitors due to the gene expression levels obtained. Plant sterols are essential components of membrane lipids, which contributing to their fluidity and permeability. Besides their cholesterol-lowering properties, they also have anti-inflammatory, antidiabetic and anticancer activities. Squalene, which is phytosterol precursor, is widely used in medicine, foods and cosmetics due to its anti-tumor, antioxidant and anti-aging activities. Nowadays, vegetable oils constitute the main sources of phytosterols and squalene, but their isolation and purification involve complex extraction protocols and high costs. In this work, Daucus carota cell cultures were used to evaluate the effect of cyclodextrins and terbinafine on the production and accumulation of squalene and phytosterols as well as the expression levels of squalene synthase and cycloartenol synthase genes. D. carota cell cultures were able to produce high levels of extracellular being phytosterols in the presence of cyclodextrins (12 mg/L), these compounds able to increase both the secretion and accumulation of phytosterols in the culture medium. Moreover, terbinafine induced a significant increase in intracellular squalene production, as seen after 168 h of treatment (497.0 ± 23.5 µg g dry weight-1) while its extracellular production only increased in the presence of cyclodextrins.The analysis of sqs and cas gene expression revealed that cyclodextrins did not induce genes encoding enzymes involved in the phytosterol biosynthetic pathway since the expression levels of sqs and cas genes in cyclodextrin-treated cells were lower than in control cells. The results, therefore, suggest that cyclodextrins were only able to release phytosterols from the cells to the extracellular medium, thus contributing to their acumulation. To sum up, D. carota cell cultures treated with cyclodextrins or terbinafine were able to produce high levels of phytosterols and squalene, respectively, and, therefore, these suspension-cultured cells of carrot constitute an alternative biotechnological system, which is at the same time more sustainable, economic and ecological for the production of these bioactive compounds.

Abstract
In this work, suspension-cultured cells of mung beans and safflower were used in order to analyze the effect of methyl jasmonate and/or cyclodextrins, on bioactive compound production such as phytosterols and tocopherols. The results indicated that mung bean suspension-cultured cells produced higher amount of total phytosterols and tocopherols. In particular, mung bean suspension-cultured cells produced almost 220-fold higher levels of tocopherols than safflower suspension-cultured cells in the best conditions. However, while cyclodextrins were able to enhance extracellular production of phytosterols, in the case of tocopherols, they only increased their intracellular accumulation. Our results showed that mung bean cells could be used as a highly efficient system for the production of phytosterols and tocopherols which have a wide range of biological activities. © 2017 American Institute of Chemical Engineers Biotechnol.

Abstract
In this work, transgenic lines of suspension cultured cells of Vitis vinifera cv. Monastrell containing the plasmid pMOG800-sts have been obtained. The cell growth of these transgenic cell lines decreased slightly as compared to non-transgenic suspension cultured cells, while cell viability was not affected. In addition, the elicitation with cyclodextrins and methyl jasmonate enhanced the production of trans-resveratrol, observing the highest levels of this compound in sts-expressing transgenic Vitis suspension cultured cells with the sts expression cassette in the forwards orientation. Moreover, the forwards 2 (F2) transgenic cell line produced the greater levels of trans-resveratrol in comparison with the non-transgenic cell line. In fact, when suspension cultured cells were treated with both elicitors, the accumulation of trans-resveratrol outside the cells in the F2 transgenic suspension cultured cells increased twice (1458 mg.L-1) as compared to non-transgenic cell lines (724 mg.L-1). In both cases, the levels of trans-resveratrol detected in the treatment with cyclodextrins and methyl jasmonate were greater than the sum of the individual treatments, and therefore we observed a synergistic effect in the presence of both elicitors. Moreover, the expression profile of sts gene in transgenic V. vinifera cell lines was similar to the expression profile detected for the endogenous sts gene in non-transgenic V. vinifera cell lines, being the expression levels greater in the treatment with methyl jasmonate and cyclodextrins, which was related to the high levels of trans-resveratrol found in the presence of both elicitors.

Abstract
Phytosterols are a kind of plant metabolite belonging to the triterpene family. These compounds are essential biomolecules for human health, and so they must be taken from foods. β-Sitosterol, campesterol, and stigmasterol are the main phytosterols found in plants. Phytosterols have beneficial effects on human health since they are able to reduce plasma cholesterol levels and have antiinflammatory, antidiabetic, and anticancer activities. However, there are many difficulties in obtaining them, since the levels of these compounds produced from plant raw materials are low and their chemical synthesis is not economically profitable for commercial exploitation. A biotechnological alternative for their production is the use of plant cell and hairy root cultures. This review is focused on the biosynthesis of phytosterols and their function in both plants and humans as well as the different biotechnological strategies to increase phytosterol biosynthesis. Special attention is given to describing new methodologies based on the use of recombinant DNA technology to increase the levels of phytosterols.

Abstract
In this work, suspension-cultured cells of Daucus carota were used to evaluate the effect of β-cyclodextrins on the production of isoprenoid and phenolic compounds. The results showed that the phytosterols and phenolic compounds were accumulated in the extracellular medium (15100μgL(-1) and 477.46μgL(-1), respectively) in the presence of cyclodextrins. Unlike the phytosterol and phenolic compound content, β-carotene (1138.03μgL(-1)), lutein (25949.54μgL(-1)) and α-tocopherol (8063.82μgL(-1)) chlorophyll a (1625.13μgL(-1)) and b (9.958 (9958.33μgL(-1)) were mainly accumulated inside the cells. Therefore, cyclodextrins were able to induce the cytosolic mevalonate pathway, increasing the biosynthesis of phytosterols and phenolic compounds, and accumulate them outside the cells. However, in the absence of these cyclic oligosaccharidic elicitors, carrot cells mainly accumulated carotenoids through the methylerythritol 4-phosphate pathway. Therefore, the use of cyclodextrins would allow the extracellular accumulation of both phytosterols and phenolic compounds by diverting the carbon flux towards the cytosolic mevalonate/phenylpropanoid pathway.

Abstract
In this work, suspension-cultured cells of Linum usitatissimum L. were used to evaluate the effect of two types of cyclodextrins, β-glucan and (Z)-3-hexenol separately or in combination on phytosterol and tocopherol production. Suspension-cultured cells of L. usitatissimum were able to produce high levels of phytosterols in the presence of 50 mM methylated-β-cyclodextrins (1325.96 ± 107.06 μg g dry weight(-1)) separately or in combination with β-glucan (1278.57 ± 190.10 μg g dry weight(-1)) or (Z)-3-hexenol (1507.88 ± 173.02 μg g dry weight(-1)), being cyclodextrins able to increase both the secretion and accumulation of phytosterols in the spent medium, whereas β-glucan and (Z)-3-hexenol themselves only increased its intracellular accumulation. Moreover, the phytosterol values found in the presence of hydroxypropylated-β-cyclodextrins were lower than those found in the presence of methylated-β-cyclodextrins in all cases studied. However, the results showed that the presence of methylated-β-cyclodextrins did not increase the tocopherols production and only an increase in tocopherol levels was observed when cells were elicited with 50 mM hydroxypropylated-β-cyclodextrins in combination with β-glucan (174 μg g dry weight(-1)) or (Z)-3-hexenol (257 μg g dry weight(-1)). Since the levels of tocopherol produced in the combined treatment were higher than the sum of the individual treatments, a synergistic effect between both elicitors was assumed. To sum up, flax cell cultures elicited with cyclodextrins alone or in combination with β-glucan or (Z)-3-hexenol were able produce phytosterols and tocopherols, and therefore, these elicited suspension-cultured cells of L. usitatissimum can provide an alternative system, which is at the same time more sustainable, economical and ecological for their production.

Abstract
Plants respond to various stress stimuli by activating broad-spectrum defense responses both locally as well as systemically. As such, identification of expressed genes represents an important step towards understanding inducible defense responses and assists in designing appropriate intervention strategies for disease management. Genes differentially expressed in tobacco cell suspensions following elicitation with isonitrosoacetophenone (INAP) were identified using mRNA differential display and pyro-sequencing. Sequencing data produced 14579 reads, which resulted in 198 contigs and 1758 singletons. Following BLAST analyses, several inducible plant defense genes of interest were identified and classified into functional categories including signal transduction, transcription activation, transcription and protein synthesis, protein degradation and ubiquitination, stress-responsive, defense-related, metabolism and energy, regulation, transportation, cytoskeleton and cell wall-related. Quantitative PCR was used to investigate the expression of 17 selected target genes within these categories. Results indicate that INAP has a sensitising or priming effect through activation of salicylic acid-, jasmonic acid- and ethylene pathways that result in an altered transcriptome, with the expression of genes involved in perception of pathogens and associated cellular re-programming in support of defense. Furthermore, infection assays with the pathogen Pseudomonas syringae pv. tabaci confirmed the establishment of a functional anti-microbial environment in planta.

Abstract
Suspension cultured-cells (SCC) of Daucus carota were used to evaluate the effect of methyl jasmonate and cyclodextrins, separately or in combination, on the induction of defense responses, particularly the accumulation of pathogenesis-related proteins. A comparative study of the extracellular proteome (secretome) between control and elicited carrot SCC pointed to the presence of amino acid sequences homologous to glycoproteins which have inhibitory activity against the cell-wall-degrading enzymes secreted by pathogens and/or are induced when carrot cells are exposed to a pathogen elicitor. Other amino acid sequences were homologous to Leucine-Rich Repeat domain-containing proteins, which play an essential role in defense against pathogens, as well as in the recognition of microorganisms, making them important players in the innate immunity of this plant. Also, some tryptic peptides were shown to be homologous to a thaumatin-like protein, showing high specificity to abiotic stress and to different reticuline oxidase-like proteins that displayed high levels of antifungal activity, suggesting that methyl jasmonate and cyclodextrins could play a role in mediating defense-related gene product expression in SCC of D. carota. Apart from these elicitor-inducible proteins, we observed the presence of PR-proteins in both control and elicited carrot SCC, suggesting that their expression is mainly constitutive. These PR-proteins are putative class IV chitinases, which also have inhibitory activity against pathogen growth and the class III peroxidases that participate in response to environmental stress (e.g. pathogen attack and oxidative), meaning that they are involved in defense responses triggered by both biotic and abiotic factors.

Abstract
Plant secretomes are the proteins secreted by the plant cells and are involved in the maintenance of cell wall structure, relationship between host and pathogen, communication between different cells in the plant, etc. Amalgamation of methodologies like bioinformatics, biochemical, and proteomics are used to separate, classify, and outline secretomes by means of harmonizing in planta systems and in vitro suspension cultured cell system (SSCs). We summed up and explained the meaning of secretome, methods used for the identification and isolation of secreted proteins from extracellular space and methods for the assessment of purity of secretome proteins in this review. Two D PAGE method and HPLC based methods for the analysis together with different bioinformatics tools used for the prediction of secretome proteins are also discussed. Biological significance of secretome proteins under different environmental stresses, i.e., salt stress, drought stress, oxidative stress, etc., defense responses and plant interactions with environment are also explained in detail.

Abstract
Suspension-cultured cells (SCC) are generally considered the most suitable cell systems to carry out scientific studies, including the extracellular proteome (secretome). SCC are initiated by transferring friable callus fragments into flasks containing liquid culture medium for cell biomass growth, and they are maintained in an orbital shaker to supply the sufficient oxygen that allows cell growth. SCC increase rapidly during the exponential phase and after 10-20 days (depending on the cell culture nature), the growth rate starts to decrease due to limitation of nutrients, and to maintain for decades these kinds of cell cultures is needed to transfer a portion of these SCC into a fresh culture medium. Despite the central role played by extracellular proteins in most processes that control growth and development, the secretome has been less well characterized than other subcellular compartments, meaning that our understanding of the cell wall physiology is still very limited. Useful proteomic tools have emerged in recent years to unravel metabolic network that occurs in cell walls. With the recent progress made in mass spectrometry technology, it has become feasible to identify proteins from a given organ, tissue, cells, or even a subcellular compartment. Compared with other methods used to isolate cell wall proteins, the spent medium of SCC provides a convenient, continuous, and reliable and unique source of extracellular proteins. Therefore, this biological system could be used as a large-scale cell culture from which these proteins can be secreted, easily separated from cells without cell disruption, and so, without any cytosolic contamination, easily recovered from the extracellular medium. This nondestructive cell wall proteome approach discloses a set of proteins that are specifically expressed in the remodelling of the cell wall architecture and stress defense.

Abstract
Recent studies suggest that plants secrete a large number of proteins and peptides into the extracellular space. Secreted proteins play a crucial role in stress response, communication and development of organisms. Here we review the current knowledge of the secretome of more than ten plant species, studied in natural conditions or during (a)biotic stress. This review not only deals with the classical secretory route via endoplasmic reticulum and Golgi followed by proteins containing a known N-terminal signal peptide, but also covers new findings about unconventional secretion of leaderless proteins. We describe alternative secretion pathways and the involved compartments like the recently discovered EXPO. The well characterized secreted peptides that function as ligands of receptor proteins exemplify the biological significance and activity of the secretome. This article is part of a Special Issue entitled: An Updated Secretome.

Induction of trans-resveratrol and extracellular pathogenesis-related proteins in elicited suspension cultured cells of Vitis vinifera cv Monastrell. JOURNAL OF PLANT PHYSIOLOGY 2013; 170:258-64. [PMID: 23127362 DOI: 10.1016/j.jplph.2012.10.003] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/17/2012] [Revised: 10/04/2012] [Accepted: 10/07/2012] [Indexed: 05/08/2023]
Abstract
Suspension-cultured cells of Vitis vinifera cv Monastrell were used to investigate the effects of methyljasmonate, ethylene and salicylic acid separately or in combination with cyclodextrins on both trans-resveratrol production and the induction of defense responses. The results showed that the addition of methyljasmonate or ethylene to suspension-cultured cells jointly treated with cyclodextrins and salicylic acid provoked a decrease of trans-resveratrol levels suggesting that salicylic acid has a negative and antagonistic effect with methyljasmonate or ethylene on trans-resveratrol production. Likewise, the exogenous application of these compounds induced the accumulation of pathogenesis-related proteins. Analysis of the extracellular proteome showed the presence of amino acid sequences homologous to an specific β-1,3-glucanase, class III peroxidases and a β-1,4-mannanase, which suggests that these signal molecules could play a role in mediating defense-related gene product expression in V. vinifera cv Monastrell. Apart from these inducible proteins, other proteins were found in both the control and elicited cell cultures of V. vinifera. These included class IV chitinase, polygalacturonase inhibitor protein and reticuline oxidase-like protein, suggesting that their expression is constitutive being involved in the modification of the cell wall architecture during cell culture growth and in the prevention of pathogen attack.
