The functions of microtubules and actin filaments during various processes that are essential for the growth, reproduction and survival of single plant cells have been well characterized. A large number of plant structural cytoskeletal or cytoskeleton-associated proteins, as well as genes encoding such proteins, have been identified. Although many of these genes and proteins have been partially characterized with respect to their functions, a coherent picture of how they interact to execute cytoskeletal functions in plant cells has yet to emerge. Cytoskeleton-controlled cellular processes are expected to play crucial roles during plant cell differentiation and organogenesis, but what exactly these roles are has only been investigated in a limited number of studies in the whole plant context. The intent of this review is to discuss the results of these studies in the light of what is known about the cellular functions of the plant cytoskeleton, and about the proteins and genes that are required for them. Directions are outlined for future work to advance our understanding of how the cytoskeleton contributes to plant organogenesis and development.
微管和肌动蛋白丝在单细胞植物生长、繁殖和存活所必需的各种过程中的功能已得到充分表征。大量植物结构细胞骨架或细胞骨架相关蛋白以及编码此类蛋白的基因已被鉴定。尽管这些基因和蛋白中的许多在功能方面已得到部分表征，但它们如何相互作用以在植物细胞中执行细胞骨架功能的连贯图景尚未出现。细胞骨架控制的细胞过程预计在植物细胞分化和器官发生过程中发挥关键作用，但这些作用究竟是什么仅在有限数量的全植物研究中进行了调查。本综述的目的是根据对植物细胞骨架的细胞功能以及实现这些功能所需的蛋白质和基因的了解，讨论这些研究的结果。概述了未来工作的方向，以促进我们对细胞骨架如何促进植物器官发生和发育的理解。
