Brief bio: Joined in Professor Jiming Gong’s group at CEMPS, CAS for PhD thesis since 2015.  Gong lab aims to address the basic theories underlying plant nutrient use efficiency and heavy metal phytoremediation. My research found that the defensin gene DEF8 is highly expressed in rice grains. DEF8 is localized to phloem and functions to specifically mediate Cd loading into xylem and phloem Cd unloading through chelation and secretion, providing an ideal molecular target for breeding low grain Cd rice.

个人简介：自2015年加入中国科学院分子植物科学卓越创新中心龚继明研究组攻读博士学位。龚继明研究组致力于解析植物营养利用效率和重金植物修复的基础理论问题。我们的研究发现防御素基因DEF8在水稻籽粒高表达。DEF8定位在韧皮部，通过螯合分泌的方式特异调控Cd向木质部的装载以及籽粒韧皮部镉的卸载，为低镉水稻育种提供了新的分子靶标。
