Plants have to deal with reactive oxygen species (ROS) production, since it could potentially cause severe damages to different cellular components. On the other hand, ROS functioning as important second messengers are implicated in various developmental processes and are transiently produced during biotic or abiotic stresses. Furthermore, the microtubules (MTs) play a primary role in plant development and appear as potent players in sensing stressful situations and in the subsequent cellular responses. Emerging evidence suggests that ROS affect MTs in multiple ways. The cellular redox status seems to be tightly coupled with MTs. ROS signals regulate the organization of tubulin cytoskeleton and induce tubulin modifications. This review aims at summarizing the signaling mechanisms and the key operators orchestrating the crosstalk between ROS and tubulin cytoskeleton in plant cells. The contribution of several molecules, including microtubule associated proteins, oxidases, kinases, phospholipases, and transcription factors, is highlighted.
植物必须应对活性氧（ROS）的产生，因为它可能会对不同的细胞成分造成严重损害。另一方面，作为重要第二信使的ROS参与各种发育过程，并在生物或非生物胁迫期间短暂产生。此外，微管（MTs）在植物发育中起主要作用，并且在感知应激情况和随后的细胞反应中似乎是重要参与者。新出现的证据表明，ROS以多种方式影响MTs。细胞氧化还原状态似乎与MTs紧密相关。ROS信号调节微管蛋白细胞骨架的组织并诱导微管蛋白修饰。本综述旨在总结植物细胞中ROS与微管蛋白细胞骨架之间相互作用的信号传导机制和关键调控因子。强调了几种分子的作用，包括微管相关蛋白、氧化酶、激酶、磷脂酶和转录因子。
