植物发育与免疫应答的细胞信号网络 研究组 课题组长:孔照胜 研究员 博士生导师 | ||
研究方向、内容及意义 课题组主要致力于植物发育与免疫应答的细胞信号网络研究。植物细胞骨架,包括微管(Microtubules, MTs)与微丝(Actin Filaments, F-actin),与细胞质膜以及细胞壁组成一个植物细胞特有的、高度动态的细胞骨架-质膜-细胞壁连续体(Cytoskeleton- Plasmamembrane-Cell Wall Continuum)。基于细胞骨架-质膜-细胞壁连续体,植物细胞形成了复杂而有序的细胞信号网络,时刻响应发育与环境信号,进行活跃的细胞骨架重排与细胞壁重构、细胞区室化(Cellular compartmentation)与细胞内稳态(Cellular homeostasis)重建,从而保障植物完成发育进程或者适应环境变化。特别是在植物与微生物相互作用过程中,细胞骨架-质膜-细胞壁连续体作为生物互作的第一道屏障(或免疫防线),在宿主与菌相互作用界面(Plant-Microbe Interface)形成过程中发挥至关重要作用,同时也是微生物(病原菌或共生菌)分泌的效应蛋白或毒力因子的重要靶标。 课题组主要有两个研究方向: 1.细胞骨架-质膜-细胞壁连续体时空调控植物细胞形态建成 2.植物-微生物互作的细胞信号网络 | ||

代表性工作1. KTN80介导植物细胞中微管的精准切割 左图显示KTN80四突变体ktn80.1234中KTN1不能被招募至微管上、不发生切割,而在KTN1的突变体lue1中KTN80仍然能够特异定位,但不能切割微管;右模式图描绘Katanin KTN1/KTN80复合体的组装及作用机制。(Wang et al, 2017; EMBO Journal) |
代表性工作3:揭示KCBP协同调控微管与微丝动态,决定表皮毛形态建成 左图:右上部为不同视角三维重构的拟南芥表皮毛中微管阵列:快速伸长的表皮毛分支会形成横向排列、密度趋向顶端的微管环,但其顶端存在一个微管缺失区域。左下部图为三维重构的分支起始阶段表皮毛中KCBP定位以及微管与微丝:KCBP马达蛋白在表皮毛中也呈梯度,且定位于微管上,但在顶端特异地富集在微管缺失区域;顶端富集的KCBP与微丝帽子部位相吻合,推测参与微丝帽子的组装与维持。右动图:三维重构方式展示拟南芥表皮毛中的微管架构。(Tian et al., 2015; eLIFE) | |
代表性工作2. 发现了 augmin复合体在周质微管上的作用机制 上图显示在拟南芥叶表皮细胞中augmin复合体招募γ-Tubulin复合体到原已存在的周质微管上并引发新生微管成核,包括叉状成核(Branching nucleation)和平行成核(Parallel nucleation)两种形式(Liu et al, 2014; Current Biology);下图显示我们进一步发现augmin 复合体除了介导微管成核之外,还有一个之前从未报道过的功能:负向调控由微管切割蛋白katanin介导的微管切割。活细胞显微成像发现augmin更倾向于定位在微管交叉点上,并且通过抑制katanin的切割、稳定微管交叉构象,来调控微管动态重组与细胞形态建成(Wang et al, 2018; Current Biology)。 |
代表性工作4. 揭示了V型肌球蛋白Myosin5介导的分泌装置在大丽轮枝菌与棉花互作中的重要作用 左图显示大丽轮枝菌V型肌球蛋白Myosin5编码基因的敲除突变体对宿主棉花的致病力显著下降(A);显微观察发现Myosin5在大丽轮枝菌菌丝生长过程中定位在菌丝顶端,与囊泡贮存中心“顶体”共定位(C);分泌蛋白组数据也表明敲除突变体菌株分泌能力有缺陷(B),由此证明Myosin5作为分泌装置的重要组分,调节大丽轮枝菌致病相关因子的分泌,在大丽轮枝菌与宿主植物互作的过程中发挥重要作用。右图为文章发表当期Environmental Microbiology杂志的封面,显示棉花植物感染黄萎病后维管束发生褐变。 | |
