课 题 组:水稻籽粒发育调控

本人简历

     20027月年于华中科技大学获生物技术学士学位,20107月年于中国科学院遗传与发育生物学研究所获遗传学博士学位,随后留所任助理研究员,20131月起任副研究员,20147月至10月为美国爱荷华州立大学访问学者,201612月由中国农科院作物科学研究所以青年英才B类引进任研究员。

研究方向

1)水稻籽粒相关性状及种子发育过程受调控的分子遗传机制;(2)作物激素油菜素内酯功能机制解析。课题组目前集中在油菜素内酯对水稻粒型和粒重调控机理的研究,将扩展到各种激素与环境协同调控水稻种子发育及灌浆过程的分子机制,并深入解析油菜素内酯调控作物各种生物学过程的分子机制,最终利用相关知识对作物进行分子设计改良。

主要贡献

克隆鉴定了DLTGSK2GL2等水稻株型和粒型调控基因,揭示了两大株高调控激素油菜素内酯和赤霉素之间的关系,深入阐释了油菜素内酯控制水稻株型、株高、粒重等多方面的分子机制与遗传调控网络,提出油菜素内酯下游功能基因的特异性在作物分子设计上的潜在应用价值。
