Plant endoplasmic reticulum (ER) remodelling is likely to be important for its function in targeted protein secretion, organelle interaction and signal exchange. It has been known for decades that the structure and movement of the ER network is mainly regulated by the actin cytoskeleton through actin motor proteins and membrane-cytoskeleton adaptors. Recent discoveries also revealed alternative pathways that influence ER movement, through a microtubule-based machinery. Therefore, plants utilize both cytoskeletal components to drive ER dynamics, a process that is likely to be dependent on the cell type and the developmental stages. On the other hand, the ER membrane also has a direct effect towards the organization of the cytoskeletal network and disrupting the tethering factors at the ER-PM interface also rearranges the cytoskeletal structure. However, the influence of the ER network on the cytoskeleton organization has not been studied. In this review, we will provide an overview of the ER-cytoskeleton network in plants, and discuss the most recent discoveries in the field.
植物内质网（ER）重塑可能对其在靶向蛋白分泌、细胞器相互作用和信号交换中的功能很重要。几十年来，人们已经知道 ER 网络的结构和运动主要通过肌动蛋白马达蛋白和膜-细胞骨架衔接蛋白被肌动球蛋白调节。最近的发现还揭示了通过基于微管的机制影响 ER 运动的替代途径。因此，植物利用两种细胞骨架成分来驱动 ER 动力学，这一过程可能依赖于细胞类型和发育阶段。另一方面，内质网膜也直接影响细胞骨架网络的组织，破坏 ER-PM 界面的连接因子也会重新排列细胞骨架结构。然而，内质网网络对细胞骨架组织的影响尚未得到研究。在这篇综述中，我们将对内质网-细胞骨架网络在植物中的作用进行概述，并讨论该领域的最新发现。
