| Research Abstract |
Our studies revealed that plant immune responses were regulated by both membrane traffic and degradation system. We also established the real-time monitoring system of autophagy in tobacco BY-2 cells as well as rice, and found the dynamic changes of autophagy during the induction of immune responses in plant cells. In addition, we identified several autophagy mutants (Osatgs) from rice, and functional analyses of mutants revealed that autophagy plays critical roles in during reproductive development in rice. We believe that these findings are useful for improving stress resistance in many crops.
