Brief Bio: I enrolled as a graduate student at the Institute of Crop Science, Chinese Academy of Agricultural Sciences (ICS, CAAS) in 2011. From then on, I engaged in the functional genomic research in Arabidopsis and soybean under the direction of my mentor Prof. Bin Liu at ICS. This study was conducted in cooperation with Jixian Zhai Laboratory of South University of Science and Technology. We knocked out the two DCL2 co-orthologous genes in soybean by CRIPSR/Cas9 engineered technology. We found that loss-of-function of both DCL2a and DCL2b genes altered seed coat color from yellow to brown. Then we revealed the molecular mechanism of how the DCL2s regulate seed coat color through generating the 22-nt endogenous siRNAs targeting the CHS genes in soybean. In the future, I will continue to study the function of genes associated with key agronomic traits in soybean.

个人简介：于2011年进入中国农业科学院作物科学研究所，在刘斌研究员课题组攻读博士学位，主要从事拟南芥和大豆功能基因组研究。本研究与南方科技大学翟继先实验室合作，通过CRIPSR技术对大豆的DCL2基因进行定点敲除，发现突变体的种皮变为棕色，并揭示DCL2调控大豆种皮色的分子机制。后期将继续从事大豆功能基因组相关研究。
