Brief bio: Under the direction of Prof. Junping Gao and Nan Ma, I worked on the molecular mechanisms how auxin controls floral organ identity for my doctoral degree. We found that auxin levels influence organ specification and changes in auxin levels influence homeotic transformation between petals and stamens in rose. The PIN-FORMED-LIKES (PILS) gene RhPILS1 governs auxin levels in floral buds during floral organogenesis. RhAUXIN RESPONSE FACTOR 18 (RhARF18) encodes a transcriptional repressor of the C-class gene RhAGAMOUS (RhAG) and governs stamen–petal organ specification in an auxin-dependent manner. Moreover, RhARF18 physically interacts with the histone deacetylase (HDA) RhHDA6. We propose a model that auxin homeostasis controls floral organ identity via regulating transcription of RhAG by ARF18-HDA6 module. My current research focuses on the function analysis of sRNA in male fertility in rice

个人简介：攻读博士学位期间，我在高俊平和马男教授的指导下开展生长素调控月季花器官发育机制的研究。我们发现生长素含量的变化影响月季花瓣和雄蕊之间的同源转变。花器官发育过程中，PIN-FORMED-LIKES (PILS) 基因RhPILS1调控花芽中的生长素含量，生长素通过RhARF18-RhHDA6模块调节C-class基因RhAG的转录，进而调控月季花器官的发育。目前，我在深圳大学开展sRNA调控水稻雄性育性发育的研究。
