胡玉欣,男,博士,研究员, 博士生导师。

    1963年9月出生于河南省伊川县,1984年和1987年分别在河南师范大学和山西农业大学获学士和硕士学位,2000年在中国科学院遗传研究所获博士学位。1988年至2001年在河南大学任教, 2001-2005年新加坡国立大学任Research Fellow, 2005年入选中科院“百人计划”。现任中科院植物所研究员,国家植物基因研究中心(北京)项目科学家。迄今发表论文30余篇(部),已培养硕士和博士7名。

主要研究工作:

[1] 植物器官发生和发育的分子调控

以模式植物拟南芥和作物为材料,研究器官发生和器官发育中细胞分裂、分化和大小的分子控制,解析植物激素信号和环境信号对器官发育和器官大小决定的分子基础,鉴定控制器官发育和大小控制的重要功能基因,为作物分子设计提供依据。

[2] 植物激素在植物细胞脱分化和分化过程中的作用的分子基础

主要以拟南芥为主要材料,研究植物激素调控植物细胞脱分化和分化过程的分子基础和以及植物细胞全能性获得和干细胞组织中心重建的分子机制。
