South Lake News (Correspondent Chen Wenkang Yang Ning) On March 25, 2022, the journal Science published online the research paper "Convergent selection of a WD40 protein that enhances grain by Yan Jianbing's team of our school and Li Jiansheng and Yang Xiaohong's team of China Agricultural University".

About 10,000 years ago, ancient humans began to domesticate animals and plants, and the human life>

After 18 years, the joint research team of China Agricultural University and Huazhong Agricultural University, three generations of teachers and students have continued to tackle this problem and conducted systematic research from the two levels of genes and genomes

Further, this study conducted an in-depth analysis of the scope and mechanism of convergent selection in maize and rice at the genome-wide level, and detected a total of 490 homologous gene pairs that underwent convergent selection

The study also used gene editing technology to create new materials for KRN2 and OsKRN2 gene functional knockout

Professor Yan Jianbing from the State Key Laboratory of Crop Genetic Improvement and Hubei Hongshan Laboratory, and Professor Li Jiansheng and Yang Xiaohong from China Agricultural University are the co-corresponding authors of the paper

Abstract

A better understanding of the extent of convergent selection among crops could greatly improve breeding programs.
