Cytoskeleton in Plant Immunity: Spatiotemporal Dynamics from Perception to Defense Execution

XLXuandong LiuHQHongping QianDLDuxian Lu

Key Points

  • The research aims to explore the role of the cytoskeleton in plant immune responses and its implications for agricultural production.
  • Comprehensive review of literature on cytoskeleton functions in plant immunity
  • Analysis of cytoskeletal rearrangements in response to pathogen recognition
  • Discussion on technologies like super-resolution imaging and multi-omics approaches to study cytoskeleton-immune interactions.
  • Cytoskeleton rapidly reorganizes after pathogen recognition to mediate immune responses.
  • It regulates calcium flow, reactive oxygen species production, and hormone signaling interactions.
  • Pathogen effectors target cytoskeletal components to inhibit immune responses and promote infection.

Abstract

植物病原微生物引发的病害严重影响农业生产和生态安全。为抵御侵染,植物形成了以PTI和ETI为核心的多层先天免疫系统。细胞骨架作为由微丝与微管组成的高度动态网络,不仅在细胞生长与运输中发挥结构与动力学功能,还在免疫识别、信号转导及防御执行中充当关键调控枢纽。近年的研究揭示,细胞骨架可在病原识别后迅速发生重排,参与调控Ca²⁺流动、活性氧爆发、激素信号交叉对话,并通过调节胞吞、膜蛋白动态、细胞壁加固、胞间连丝关闭及程序性细胞死亡精确执行免疫反应。同时,多类病原效应子可直接靶向微丝或微管,破坏骨架稳定性以实现免疫抑制与侵染扩展。本文综述当前关于细胞骨架在植物免疫识别、信号整合及防御执行中的功能研究,重点剖析其作为免疫调控网络核心节点的作用机制。并展望未来可能的研究方向,运用超分辨率活体成像、单分子动态追踪及多组学联合分析等技术解析细胞骨架与免疫系统间的互作网络,以期为作物抗病遗传改良及绿色防控策略的设计提供新思路与分子靶标。
