Brief bio: During doctoral study period, we enhanced the Agrobacterium-mediated transformation of upland cotton and explored the essential role of GhPEL gene, encoding a pectate lyase, in cotton fiber elongation. When worked in the Shanghai Institute of Plant Physiology & Ecology during 2009 to 2016, we constructed an efficient Agrobacterium-mediated transformation of two elite aspen hybrid clones, illuminated functions of a NAC TF PtSND2 in wood formation and poplar growth, and systematically researched the biofunctions of fasciclin-like arabinogalactan proteins PtFLAs in poplar wood formation and tension wood formation. Our studies were published in Plant Cell Reports, Plant Molecular Biology, Scientific Reports, Tree Physiology, Journal of Experimental Botany et al. and cited by 251 times so far。From 2016, I began to work on the maize early endosperm development and the molecular mechanism of vitreous endosperm formation in Yongrui Wu’s lab. Recently, we performed approaches of genetics, molecular biology and cell biology to explore the molecular mechanism of a maize kinesin protein KIN11 (ZmVKS1) in early endosperm development. We found that VKS1 played important roles in mitosis and cytokinesis of early endosperm cells by affecting the microtubule system, thereby regulated the cell number of endosperm and the kernel size. This work opens a door for us to further study the mechanism of maize early endosperm development.

本人简介: 博士期间建立了棉花遗传转化体系并系统研究了果胶裂解酶基因GhPEL在棉纤维发育中的生物学功能。2009 -2016年在中国科学院上海植物生理生态研究所从事杨树木质发育机理的研究，首先建立了杨树栽培种的遗传转化体系，同时成功解析了NAC转录因子PtSND2在木质发育中的分子机理，另外系统研究了阿拉伯半乳糖基因PtFLAs在木质发育和应拉木形成中的分子机理。研究结果发表在Plant Cell Reports, Plant Molecular Biology, Scientific Reports, Tree Physiology, Journal of Experimental Botany等期刊，总引用次数为251次。2016年至今在植生所巫永睿课题组从事玉米胚乳早期发育机理和硬质胚乳形成机理的研究。最近，我们通过遗传学、分子生物学和细胞学的方法解析了驱动蛋白KIN11（ZmVKS1）在玉米早期胚乳发育中作用机制，发现VKS1通过影响胚乳细胞有丝分裂中微管系统的形成从而影响早期胚乳细胞的分裂，最终影响胚乳细胞数目和籽粒大小。这项工作的完成为我们进一步揭示玉米早期胚乳发育的分子机理奠定了坚实基础。
