Plant growth and development are a genetically predetermined series of events but can change dramatically in response to environmental stimuli, involving perpetual pattern formation and reprogramming of development. The rate of growth is determined by cell division and subsequent cell expansion, which are restricted and controlled by the cell wall-plasma membrane-cytoskeleton continuum, and are coordinated by intricate networks that facilitate intra- and intercellular communication. An essential role in cellular signaling is played by calcium ions, which act as universal second messengers that transduce, integrate, and multiply incoming signals during numerous plant growth processes, in part by regulation of the microtubule cytoskeleton. In this review, we highlight recent advances in the understanding of calcium-mediated regulation of microtubule-associated proteins, their function at the microtubule cytoskeleton, and their potential role as hubs in crosstalk with other signaling pathways.
植物的生长和发育是一系列由基因预先决定的事件，但可以对外界环境刺激做出显著变化，涉及到不断的模式形成和发育的重新编程。生长速度由细胞分裂和随后的细胞扩张决定，而这些过程受到细胞壁-质膜-细胞骨架连续体的限制和控制，并通过复杂的网络进行协调，这些网络促进了细胞内和细胞间的通讯。钙离子在细胞信号转导中起着至关重要的作用，作为通用的第二信使，在许多植物生长过程中，钙离子可以传递、整合和放大传入信号，部分是通过调节微管细胞骨架来实现的。在这篇综述中，我们强调了最近在理解钙介导的微管相关蛋白调节、它们在微管细胞骨架中的功能以及它们作为与其他信号通路交叉对话的枢纽的潜在作用方面的进展。
