Abstract
Jasmonic acid and its derivatives (JAs) are phytohormones that have essential roles in plant defenses against biotic and abiotic stresses.
The up- and down-regulation of defense responses is partly dependent on signaling pathways mediated by JAs, generally involving the transcriptional regulation of transcription factors.
In addition to the typical model plant Arabidopsis (a dicotyledon), advances in research on rice have made it notable as a model monocotyledon for creating innovative pest control traits and studying the JA signaling pathway.
In this mini-review, we introduce potential functions for the rice bHLH transcription factor RERJ1, the expression of which is rapidly induced by wounding.
On the basis of the highly dynamic nature of the expression of RERJ1, we assume the functionality of this protein with a special focus on the onset of JA-mediated events in rice.
