Abstract

Jasmonic acid (JA), a plant hormone, has roles in regulating stress response and development. We identified transcription factors induced by jasmonates (JAs) and wounding using microarray analysis. In this study, we aimed to reveal the JA signaling by understanding physiological function of JA-responsive transcription factors. <br>One of the JA-response transcription factor INU1 is induced strongly by JAs and wounding at early time after treatment and this suggests INU1 has important roles in JA signaling. In addition, expression of INU1 depends on JA because INU1 expression was markedly reduced in JA biosynthesis mutant aos. We performed microarray analysis for methyl jasmonate dependent gene expression in inu1 mutant and found that genes related to flavonoid biosynthesis are up-regulated in inu1. By metabolome analysis, flavonoid contents were found to be changed in inu1. These results indicate that INU1 negatively regulates flavonoid biosysthesis.
