植物抗逆分子遗传学

植物抗逆分子遗传学，主要包括：

（1）水稻抗旱QTL候选基因的挖掘和功能鉴定；

（2）水稻耐旱相关转录调控因子的功能和作用机制研究；

（3）水稻深根性候选基因的挖掘和功能研究。

近年来对在植物耐盐中起重要作用的Na+/H+逆向转运蛋白基因进行了克隆、表达模式分析和功能研究，揭示了此类基因同样具有显著的抗旱功能。同时，利用DNA改组技术结合酵母筛选系统对此类基因进行了定向进化，通过筛选得到了一个耐盐性显著提高的新Na+/H+逆向转运蛋白基因。对此新基因进行了初步的生化机制研究，为此类基因结构与功能关系的研究提供了新的证据。发表了4篇SCI论文，申请了2项国家发明专利和1项国际PCT专利。
