在高等植物中,基于微管(MT)和基于肌动蛋白细丝(AF)的结构在有丝分裂和胞质分裂中起着重要的作用。在植物细胞中,除了有丝分裂纺锤体外,由皮质MTS和AFS组成的一条带,即前期带(PPB)的进化也很明显。这条带在有丝分裂开始之前预测了一个特定的分裂平面。在细胞质分裂过程中,另一种植物特有的细胞骨架结构称为膜质,它引导小泡形成新的细胞壁。此外,据报道,一些与细胞骨架相关的蛋白参与了PPB、有丝分裂纺锤体和成纤维细胞的形成和功能。本文综述了在植物细胞有丝分裂和胞质分裂过程中介导细胞骨架排列的细胞骨架相关蛋白的研究现状,并讨论了MTS和AFS在有丝分裂和胞质分裂过程中的相互作用。
In higher plants, microtubule (MT)-based, and actin filament (AF)-based structures play important roles in mitosis and cytokinesis. Besides the mitotic spindle, the evolution of a band comprising cortical MTs and AFs, namely, the preprophase band (PPB), is evident in plant cells. This band forecasts a specific division plane before the initiation of mitosis. During cytokinesis, another plant-specific cytoskeletal structure called the phragmoplast guides vesicles in the creation of a new cell wall. In addition, a number of cytoskeleton-associated proteins are reportedly involved in the formation and function of the PPB, mitotic spindle, and phragmoplast. This review summarizes current knowledge on the cytoskeleton-associated proteins that mediate the cytoskeletal arrays during mitosis and cytokinesis in plant cells and discusses the interaction between MTs and AFs involved in mitosis and cytokinesis.
