Plant cells grow through increases in volume and cell wall surface area. The mature morphology of a plant cell is a product of the differential rates of expansion between neighboring zones of the cell wall during this process. Filamentous actin arrays are associated with plant cell growth, and the activity of actin-binding proteins is proving to be essential for proper cell morphogenesis. Actin-nucleating proteins participate in cell expansion and cell plate formation whereas the recycling of actin monomers is required to maintain actin dynamics and controlled growth. Coordination of actin-binding protein activity and other aspects of cytoskeletal behavior during cell development maintains cohesive cell expansion. Emerging plant signaling networks are proving to be powerful regulators of morphology-shaping cytoskeletal activity, and in this review we highlight current research in actin network regulation.
植物细胞通过体积和细胞壁表面积的增加而生长。在此过程中，植物细胞的成熟形态是细胞壁相邻区域之间不同扩张速率的产物。丝状肌动蛋白阵列与植物细胞生长相关，并且肌动蛋白结合蛋白的活性对于正确的细胞形态发生至关重要。肌动蛋白成核蛋白参与细胞扩张和细胞板形成，而肌动蛋白单体的循环利用对于维持肌动蛋白动力学和受控生长是必需的。在细胞发育过程中，肌动蛋白结合蛋白活性与细胞骨架行为的其他方面的协调维持了细胞的连贯扩张。新兴的植物信号网络已被证明是形态塑造细胞骨架活性的强大调节因子，在本综述中，我们重点介绍了肌动蛋白网络调节的当前研究。
