骨干:童红宁 - 中国农业科学院作物科学研究所


 



姓名:童红宁    性别:男
职称:研究员
电子邮箱:tonghongning@caas.cn
创新小组:水稻籽粒和种子发育
 

组长简介:
        2002年于华中科技大学获生物技术学士学位,2010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,随后历任助理研究员、副研究员,2016年作为“青年英才B类人选”由中国农科院作物科学研究所引进,任所级研究员。
研究方向:
       个人目前主要从事作物激素调控水稻重要农艺性状的分子机制研究,集中在油菜素内酯对水稻粒型和粒重特异性调控机理的研究,将扩展到各种激素协同调控水稻种子发育及灌浆过程的分子机制,并利用相关知识对作物进行品质改良。
主要贡献:
       克隆鉴定了DLT、GSK2、GL2等基因,揭示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,部分阐明了高低浓度激素对植物生长调控的逆转机制,提出并部分证明了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。
在研项目:
       中国农科院青年英才启动经费
       国家自然科学基金重大研究计划培育项目(主持人)
       国家自然科学基金重大研究计划重点项目(主要参与人)
