Transcriptomic analysis of Arabidopsis wild-type (Col-0), phyb-9, jaz10 and jaz10phyB-9 plants to methyl jasmonate (MeJA)

ABSTRACT: We used Affymetrix 1.0 ST arrays to compare the transcriptome of 4 weeks‐day‐old plants sprayed with 250uM of MeJA or mock (control). For the experiments we used wild-type (Col-0), phyB-9 and jaz10 single mutants and jaz10phyb double mutant. Samples were harvested after 3hours of induction with MeJA or mock. We performed a first analysis with the transcriptomes of wild‐type (Col-0) to identify those group of genes that are up‐ and down‐regulated by MeJA treatment (2 fold-changes). We founded 719 genes whose expression was statistically significantly different between the two treatments. To gain knowledge into the regulation of phyB over these set of 719 genes, we contrasted their expression levels against phyB transcriptome. By cluster analysis, we identified five major groups of genes, where in two of them the transcript levels increased in presence of MeJA (clusters 1 and 2) and three whose expression decrease after MeJA treatment (Cluster 3, 4 and 5).
