研究方向:
课题组长期从事模式生物个体发育机制研究。近年以小立碗藓(Physcomitrium patens)为对象,揭示小G蛋白在细胞极性生长和不对称分裂中的重要作用,提出植物细胞不对称分裂的通用模型;在苔藓中建立以CRISPR/Cas9为基础的突变敲入技术。小立碗藓是早期陆生植物的代表性分支之一,生长方式包括二维线性(原丝体)和三维多轴向(配子托)形式。课题组目前关注苔藓植物形态发生和体轴建立的细胞分子机制和基本原理,探讨植物从水生向陆生过度阶段,细胞结构、行为与发育模式的适应性改变。研究手段包括基因敲除与敲入、活体细胞成像、体外生化分析等,研究方向包括:
1. 植物细胞极性与不对称分裂
2. 植物细胞的生长、形态发生和维持
3. 细胞骨架和胞内运输
4. 遗传工具的开发与应用
