植物内质网（ER）的重塑可能是重要的，其功能的目标蛋白质分泌，细胞器的相互作用和信号交换。几十年来，人们已经知道ER网络的结构和运动主要是由肌动蛋白细胞骨架通过肌动蛋白马达蛋白和膜-细胞骨架衔接子来调节的。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，这一过程可能取决于细胞类型和发育阶段。另一方面，ER膜也对细胞骨架网络的组织具有直接影响，并且破坏ER-PM界面处的束缚因子也重排细胞骨架结构。然而，ER网络对细胞骨架组织的影响尚未研究。在这篇综述中，我们将概述植物中的ER细胞骨架网络，并讨论该领域的最新发现。
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.
