Project description:Illumina HiSeq technology was used to generate mRNA profiles from Populus tremula x alba INRA 717-1B4 roots treated with Methyl jasmonate. Samples were harvested after two weeks either from untreated control roots or from Methyl jasmonate treated roots. Paired-end (2X100bp) reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) using CLC Genomics Workbench 6.

Project description:Jasmonate is an essential phytohormone involved in plant development and stress responses. Jasmonate perception occurs through the COI nuclear receptor allowing to target the JAZs repressors for degradation by the 26S proteasome. Consequently, repressed transcription factors are released and expression of JA-responsive genes is induced. In rice, three OsCOI genes have been identified, OsCOI1a and the closely related OsCOI1b homolog, and OsCOI2. While a role for OsCOI-1a and -1b genes was previously established in plant defense or leaf senescence, evidence for an important role of OsCOI2 in plant development, jasmonate-signaling and defence emerged only recently. To decipher the role of OsCOI2 in regulating jasmonate responses, we used rice mutant lines, edited both in the OsCOI1a and OsCOI1b genes, or in the OsCOI2 gene. Rice roots from WT and oscoi lines were treated by jasmonate to establish the molecular responses of each line, at the transcriptomic and metabolomic levels. RNA-seq data indicate that OsCOI2 is the main actor of the large transcriptional reprogramming observed after a JA challenge in rice roots. A series of transcription factors with an OsCOI2-dependent expression was identified, including transcription factors known to have a role in root development or stress response. An OsCOI2-dependent expression was detected for genes involved in specific processes or pathways such as photosynthesis, cell-growth and secondary metabolite biosynthesis (phenylpropanoids and diterpene phytoalexins). Functional redundancy between OsCOI1a/b and OsCOI2 can be shown for some genes, even if a lower response usually occurred in oscoi2 plants compared to oscoi1ab plants. Metabolic data revealed a shift from the primary metabolism to the secondary metabolism that is mainly OsCOI2-dependent. Differential accumulation of oryzalexins was also observed in oscoi lines.These data validate the major role of OsCOI2 in JA responses in rice roots. OsCOI2 is the major regulator of specialized metabolic pathways related to development and production of secondary metabolites. This study suggests that OsCOI2 controls the growth-defense trade-off in response to JA.

Paired-end (2X100bp) reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) using CLC Genomics Workbench 6. mRNA profiles from Populus tremula x alba INRA 717-1B4 roots treated with Methyl jasmonate as well as from control roots were generated by paired-end (2X100bp) Illumina HiSeq sequencing. Four samples were sequenced per lane, two biological replicates per treatment.

Project description:As part of the CAGE consortium, Col-4 plants (1.04, 1.08, 1.12 or 5.10 stage) were exposed to a methyl jasmonate stimulus (or to the ethanol as a control) and leaves 1 and 2 were harvested. Hybridizations were performed using the oligo reference labeled with Cy3. The stress samples can be analyzed together with the basal/normal genomic expression patterns for Col-4 wildtype plants collectively produced by CAGE members.

Project description:The plant hormone jasmonate (JA) plays important roles in the regulation of defense responses in many plants. To clarify the response to JA in rice at gene expression level, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, custom-made; Agilent Technologies, Redwood City, CA, USA). As a result, treatment of JA caused high upregulation of many defense-related genes including pathogenesis-related (PR) genes in rice. However, many of these defense-related genes were not upregulated in JA-insensitive transgenic rice plant overexpressing JAZ8deltaC.

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.
