| Research Abstract |
Plants respond to pathogen infection a variety of defense reactions. In this study, we investigatedfunctional analysis of the key transcription factors OsWRKY53 and OsTGAP1 that are, respectively,involved in expression of antimicrobial proteins and production of phytoalexins in rice. According to chromatin immunoprecipitation-sequencing, the binding sites of OsWRKY53 and OsTGAP1 were identified comprehensively . Key information on activation mechanisms and interacting factors of these two transcription factors were also obtained.
