| Research Abstract |
In this study, we surveyed target genes of RERJ1, a key transcription factor in the jasmonic acid (JA) signaling pathway in rice, and provided the gene list for the RERJ1-target candidates includes proteinase inhibitor gene, monoterpene linalool synthase gene, and a JAZ repressor protein gene in the JA signaling under wound stress. We also found that RERJ1 plays a important roles on resistance against insect herbivory, and that inductive RERJ1 expression is highly dependent on the JA-isoleucine, an active form of JA. Based on these findings, we propose that RERJ1 is one of the key regulators involved in harbivory resistance through the positive regulation of wound-inducible genes including proteinase inhibitor gene in the JA signaling in rice.
