研究方向

微絲骨架（actin cytoskeleton）是遍布于一切真核細胞中的三維網(wǎng)狀結(jié)構(gòu)，占植物總蛋白的15-20%，在維持細胞形態(tài)、參與細胞運動、胞質(zhì)分裂和極性建立等重要細胞生理活動中起著決定性的作用。微絲骨架的動態(tài)變化是其行使各種生理功能的基礎(chǔ)，而該過程則直接受到諸多微絲結(jié)合蛋白和不同信號分子的調(diào)控。本課題組以模式作物擬南芥為材料，主要開展如下研究工作：

1. 探索植物特有的、功能未知的微絲結(jié)合蛋白；

2. 微絲骨架參與植物花粉管極性生長的分子機理；

3. 微絲骨架參與植物響應(yīng)各種非生物脅迫的分子機理；

4. 植物抗逆信號轉(zhuǎn)導(dǎo)（鈣離子）。
