Brief bio:

I joined the research group of Prof. Hanhui Kuang in Huazhong Agriculture University in 2016. The topic of my doctoral study is to dissect the genetic and mechanism of the development of leafy head in lettuce. The development of leafy head (heading) is a special agronomic trait in some vegetable crops, such as lettuce, Chinese cabbage, and cabbage. Leafy head is conducive to harvest, transportation and storage. In this study, we genetically cloned a gene (LsSAW1) controlling heading in lettuce, and elucidate that LsSAW1 regulates the development of leafy head through leaf dorsiventrality network. Our result showed that up-regulating abaxial genes and downregulating adaxial genes can promote heading. Our results can be exploited for the breeding of lettuce and other heading vegetables, and provide new gene resource for studying the molecular mechanisms on leaf development and dorsiventrality in plants.

个人简介：我于2016年进入华中农业大学匡汉晖教授课题组开始研究生的学习，课题是解析生菜叶球形成的遗传和分子机理。叶球的形成（结球）是部分蔬菜作物特有的农艺性状，如生菜、白菜、甘蓝。结球有利于采收、运输和贮藏。我们遗传克隆了一个主效的生菜结球调控基因LsSAW1，并解析了LsSAW1通过平衡叶背腹面发育来调控生菜结球的形成。我们的结果表明，上调远轴基因和下调近轴基因可以促进叶球的形成。我们的研究有利于结球生菜和其他结球蔬菜的育种，也为植物叶发育和叶背腹性调控网络的研究提供了新的基因资源。
