Transcription profiling by array of Arabidopsis cell suspensions after treatment with methyl jasmonate

ABSTRACT: The transcriptional response of Arabidopsis thaliana cell suspensions following treatment with the stress hormone methyl jasmonate (MeJA) was monitored over time 16 hours after subcultivation. Three time points were included: 30 minutes, 2 hours and 6 hours after elicitation with 50µm MeJA or DMSO as a control.

Jasmonates (JAs) are plant-specific signaling molecules that steer a diverse set of physiological and developmental processes. Pathogen attack and wounding inflicted by herbivores induce the biosynthesis of these hormones, triggering defense responses both locally and systemically. We report on alterations in the transcriptome of a fast-dividing cell culture of the model plant Arabidopsis thaliana after exogenous application of methyl JA (MeJA). Early MeJA response genes encoded the JA biosynthe ...[more]

SWATH-MS Proteomics Analysis of Persicaria minor herb upon Methyl Jasmonate elicitation

Project description:Stresses from either biotic or abiotic origins can have significant impact towards plant physiology and molecular regulation. Jasmonate acid (JA) and its derivative, methyl JA (MeJA) are hormonal cues released by plants which signal defensive response to curb the damage from such stresses. In an attempt to study the defensive response, a tropical herbal plant, Persicaria minor (P. minor) which is known for its pungent smell as well as various bioactivities including antimicrobial and anti-cancer, has been treated with MeJA to invoke the stress signaling. Such elicitation has been performed in various plants such as Arabidopsis, rice and hairy root cultures of certain herbs, yet how MeJA directly influenced the proteome of a herbal species particularly P. minor has not been previously elucidated. In this study, P. minor plants was exogenously treated with MeJA and its proteome was investigated using a new proteomics approach called SWATH-MS.

Proteome response in maize to methyl jasmonate

Project description:Jasmonic acid (JA) and methyl jasmonate (MeJA) regulate plant development, resistance to stress, and insect attack by inducing specific gene expression. However, little is known about the mechanism of plant defense against herbivore attack at a protein level. Using a high-resolution 2-DE gel, we identified 60 MeJA-responsive proteins and measured protein expression level changes. Among these 62 proteins, 43 proteins levels were increased while 11 proteins were decreased. We also found eight proteins uniquely expressed in response to MeJA treatment. The proteins identified in this study have important biological functions including photosynthesis and energy related proteins (38.4%), protein folding, degradation and regulated proteins (15.0%), stress and defense regulated proteins (11.7%), and redox-responsive proteins (8.3%). We found MeJA could not only induce plant defense mechanisms to insects, it also enhanced toxic protein production that potentially can be used for bio-control of Asian corn borer.

Transcriptional Profile of Glycyrrhiza uralensis Fisch Suspension Cell in Response to Methyl Jasmonate

Project description:Licorice (Glycyrrhiza uralensis Fisch) flavonoids have many pharmacological effects, as the main chemical component of licorice, its content directly affects the quality of licorice. Methyl jasmine (MeJA) is an important signaling molecule in the secondary metabolic pathway of plants, but the biological mechanisms that stimulating the production of licorice flavonoids and the related changes in transcriptome are still less studied. In this research, the expression of two key enzyme genes: Chalcone synthase (CHS) and Cinnamate 4-hydroxylase (C4H) in the biosynthesis pathway of licorice flavonoids was determined, and it was significantly different after 9 hours of MeJA induction. The transcriptome profiles of licorice cells at 9 hours after MeJA treatment were analyzed to investigate the transcriptional alterations of licorice cell in response to MeJA elicitation by “RNA-seq”. 151, 529 transcripts (200 bp in length) of cDNA from the samples were generated, and 116, 907 unigenes were found. MeJA appeared to stimulate a large number of genes involved in several relevant functional categories, such as carbohydrate metabolism and encoding transcription factors, 11 MYB transcription factors expressed significant differences were screened. This comprehensive description of gene expression information could help elucidate the molecular mechanism of MeJA-mediated biosynthesis of licorice flavonoids and MeJA-regulated network formation.

RNA-Seq of Brachypodium distachyon callus treated with methyl-jasmonate

Project description:The aim was to determine the changes in cell wall composition and transcriptome changes following treatment with the stress hormone precursor methyl jasmonate (MeJA) in the model grass Brachypodium distachyon. The correlation between transcript changes and cell wall composition changes allowed identification of candidate genes responsible for grass-specific features of the cell wall that are specifically changed in response to MeJA.

Detection of Methyl jasmonate (MeJA) in Plant root VOCs

Project description:Methyl jasmonate (MeJA) is a well-known plant hormone known for plant defense and plant-plant signaling. However, most of the studies are focussed on its aboveground presence and functions. Here we report that MeJA is also released by plant roots in a volatile form. More importantly, it is shown in Arabidopsis growing in natural conditions in soil.

Transcriptome analysis of mvp mutant reveals important changes in global gene expression and a role of methyl-jasmonate in vernalization and flowering in wheat

Project description:The maintained vegetative phase (mvp) mutant has a non-flowering phenotype caused by deletions including, but not limited to, the genes CYS, PHYC and VRN1. However the impact of these deletions on flowering genes and global gene expression is still unknown. In this study, we showed that these deletions caused the up-regulation of several pathogenesis related (PR) and jasmonate responsive genes using microarray analysis. Our results raise the hypothesis that jasmonates may be involved in flowering. To confirm this hypothesis, the methyl-jasmonate (MeJA) and jasmonic acid (JA) content in mvp and wild type plants was measured. The content of JA was comparable in all plants while the content of MeJA was higher in mvp plants. Our transcriptomic and chemical analyses of the mvp mutants plants reveal that the deletion of the major vernalization gene TaVRN1 induces the up-regulation of the major biotic stress related genes and the accumulation of MeJA. In addition, our results demonstrate an important role of MeJA during vernalization and flowering in wheat.
