The plant cytoskeleton undergoes dynamic remodeling in response to diverse developmental and environmental cues. Remodeling of the cytoskeleton coordinates growth in plant cells, including trafficking and exocytosis of membrane and wall components during cell expansion, and regulation of hypocotyl elongation in response to light. Cytoskeletal remodeling also has key functions in disease resistance and abiotic stress responses. Many stimuli result in altered activity of cytoskeleton‐associated proteins, microtubule‐associated proteins (MAPs) and actin‐binding proteins (ABPs). MAPs and ABPs are the main players determining the spatiotemporally dynamic nature of the cytoskeleton, functioning in a sensory hub that decodes signals to modulate plant cytoskeletal behavior. Moreover, MAP and ABP activities and levels are precisely regulated during development and environmental responses, but our understanding of this process remains limited. In this review, we summarize the evidence linking multiple signaling pathways, MAP and ABP activities and levels, and cytoskeletal rearrangements in plant cells. We highlight advances in elucidating the multiple mechanisms that regulate MAP and ABP activities and levels, including calcium and calmodulin signaling, ROP GTPase activity, phospholipid signaling, and post‐translational modifications.

细胞骨架相关蛋白活性的调节：将细胞信号与植物细胞骨架功能联系起来

植物细胞骨架会根据不同的发育和环境因素进行动态重塑。细胞骨架的重塑协调植物细胞的生长，包括细胞扩张过程中膜和壁成分的运输和胞吐作用，以及对光响应下胚轴伸长的调节。细胞骨架重塑在抗病性和非生物应激反应中也具有关键作用。许多刺激导致细胞骨架相关蛋白、微管相关蛋白 (MAP) 和肌动蛋白结合蛋白 (ABP) 的活性改变。MAPs 和 ABPs 是决定细胞骨架时空动态性质的主要参与者，在感觉中枢中发挥作用，解码信号以调节植物细胞骨架行为。而且，MAP 和 ABP 活动和水平在开发和环境响应过程中受到精确调节，但我们对这一过程的理解仍然有限。在这篇综述中，我们总结了将多种信号通路、MAP 和 ABP 活性和水平以及植物细胞中的细胞骨架重排联系起来的证据。我们强调在阐明调节 MAP 和 ABP 活性和水平的多种机制方面取得的进展，包括钙和钙调素信号、ROP GTPase 活性、磷脂信号和翻译后修饰。
