研究方向: 植物抗金属毒害机制和矿质营养吸收及调控的研究

 

个人简介:

广西杰出青年基金获得者(2016年),入选广西高校引进海外高层次人才“百人计划”(2014年)和广西第一批高层次人才(2019年)。2002和2008年在华南农业大学生物学专业分别获学士和博士学位,2008至2014年分别在日本冈山大学和新加坡国立大学生物系做博士后研究。

 

科研成果:

主要从事植物抗金属毒害机制和矿质营养吸收及调控的研究,首次克隆了三价铝转运蛋白Nrat1,揭示了铝离子是如何进入植物细胞的,阐明了Nrat1在水稻解铝毒中的作用机制,并发现决定Nrat1对铝离子选择性转运的关键基序,为作物耐铝性的遗传改良提供重要理论依据;分离出多个镉离子转运体,并解析了它们在水稻的镉耐受性及镉积累中的分子机制,为培育耐镉及低镉作物品种提供重要的理论支撑和新的基因资源;揭示了凯氏带在水稻根对矿质元素吸收中的作用机制,弥补了单子叶植物凯氏带形成机理和功能研究的匮乏,为今后培育营养元素高效利用品种提供新的理论依据。已在PNAS、 Plant Cell、Nature Communications、The Plant Journal等国际期刊发表SCI论文35篇。
