Brief bio: My major research interest is to dissect the molecular mechanism of ethylene in plant root growth and stress adaptation. I started my research career since I became a graduate student of Dr. Rongfeng Huang. During my graduate and postdoctoral study, I found that OsDOF15 acts as a link between salt and ethylene biosynthesis by coordinating the modulation of salt- and ethylene-inhibited primary root growth, and OsEIL1 mediates the crosstalk between ethylene and auxin during primary root elongation by activating the expression of YUC8/REIN7. In this study, we demonstrated that ethylene promotes GA metabolism to control cell proliferation of root meristem and primary root elongation in rice. Our long-term scientific goal is to provide valuable targets for root system architecture breeding and improve rice production in environments characterized by abiotic stress.
