Brief bio: I entered the CAS Center for Excellence in Molecular Plant Science since 2018. Under the guidance of my supervisor Prof. Chao-Feng Huang, I carried out research on aluminum resistance mechanisms in plants. We identified a PP2C.D phosphatase SAL1 in rice by a forward genetic screen and demonstrated that SAL1 positively regulates rice Al resistance by coordination with aluminum transporter NRAT1 to restrict aluminum uptake, whereas Arabidopsis PP2C.D phosphatases negatively regulate aluminum resistance via modulating malate secretion. Our results reveal different strategies adopted by rice and Arabidopsis to cope with aluminum toxicity.

个人简介：

自2018年进入中国科学院分子植物科学卓越创新中心，在导师黄朝锋研究员的指导下开展植物抗铝毒机制的研究工作。我们通过正向遗传筛选鉴定了一个水稻PP2C.D磷酸酶SAL1，阐明了SAL1通过与铝转运蛋白NRAT1协作限制铝吸收从而正调控水稻抗铝毒，而拟南芥PP2C.D磷酸酶则通过调控苹果酸分泌负调控植物抗铝毒的作用机制。我们的研究结果揭示了水稻和拟南芥应对铝毒害所采用不同的策略。
