| Research Abstract |
In this study, from the analysis of osjar1 mutant defective in jasmonoyl isoleucine production, it was suggested that JA-Ile is an actual signal molecule responsible for the expression of rice defense reaction through JA signaling, and that there are at least two JA signaling pathways, one is dependent on JA-Ile and the other is not. Based on the analysis of OsCOI1a, b, and c repressed or overexpressed transgenic plant, these F-box gene are shown to be involved in JA signaling in rice.
