Abstract

Plant cell cortical microtubules are located beneath the plasma membrane and direct the location of cellulose synthases during interphase, influencing cell morphology. Microtubule-associated proteins (MAPs) regulate these microtubules in response to growth and environmental stimuli. This review focuses on recent advances in understanding microtubule nucleation mechanisms in plants and the spatiotemporal regulation of cortical arrays via phytohormone signaling. Emphasis is placed on the conserved nature of the gamma-tubulin ring complex (γTuRC) and plant-specific components. The discussion includes the role of the Augmin complex and the distinct function of the Msd1-Wdr8 complex in plants. We also explore the effects of hormone signaling, particularly brassinosteroids, on the microtubule regulatory apparatus. The interplay between hormone signaling pathways and microtubule dynamics, including phosphorylation events and post-translational modifications, is also addressed. Finally, the impact of environmental signals and the role of protein post-translational modifications in regulating microtubule organization are suggested for future research.

植物微管成核装置及其潜在信号途径
植物细胞皮层微管位于质膜下方,在细胞间期引导纤维素合成酶的位置,影响细胞形态。微管相关蛋白(MAPs)调节这些微管,以应对生长和环境刺激。这篇综述重点介绍在了解植物微管成核机制以及通过植物激素信号对皮层阵列进行时空调控方面的最新进展。重点是γ-微管蛋白环复合体(γTuRC)和植物特异性成分的保守性。讨论内容包括 Augmin 复合物的作用以及植物中 Msd1-Wdr8 复合物的独特功能。我们还探讨了激素信号,特别是铜激素对微管调节装置的影响。我们还探讨了激素信号途径与微管动力学之间的相互作用,包括磷酸化事件和翻译后修饰。最后,对环境信号的影响和蛋白质翻译后修饰在调节微管组织中的作用提出了未来研究的建议。
