本课题组主要关注植物逆境适应过程中的分子机制：

（1）植物氮胁迫与氮信号（nitrogen stress and signaling in plants）：氮素（nitrogen, n）作为植物营养的三大要素之一，是构成植物体多种有机化合物的基本成分。植物主要以无机态氮：铵态氮（nh₄ ）、硝态氮（no₃^-）的形式吸收氮素，而氮素会直接影响植物的各项生命活动。本团队致力于研究植物对氮素营养的感知、吸收、转运以及氮素信号应答机制，首次发现硝酸根离子外排通道slah3通过平衡植物硝态氮的吸收，在缓解植物铵盐毒害过程中发挥重要作用。主要研究方向包括三方面：a.植物对高铵氮源逆境适应的分子机理；b.植物对氮素的感知与信号转导机制；c.植物对氮素的塑性反应分子机理。

（2）拟南芥类受体蛋白的生物学功能（functional analyses of receptor-like proteins, rlps）：细胞表面的受体激酶（receptor-like kinases, rlks）在细胞与周围环境之间的信号转导过程中起至关重要的作用。与类受体蛋白激酶不同，类受体蛋白只包含胞外识别域、跨膜域，通常缺乏胞内激酶结构域。本团队正在利用各种遗传学、分子生物学以及组学手段对rlp中尚未揭示功能的组分开展生物学功能研究。
