The post-translational modification is the fundamental reason for the most of the cellular signaling events. Plant shows meticulous response to survive in different environmental stresses. SUMOylation is one of the important post-translational modifications. Post-translational modifiers play a significant role in the alteration of protein stability, the interaction between proteins and the ultimate destiny of the protein. For expediting the plant to defend against the environmental stresses, conjugation of Small Ubiquitin-like Modifiers (SUMO) to intracellular proteins is the vital process. The numbers of isoform of proteins play a significant role in SUMOylation and de-SUMOylation reaction in SUMO process. SUMOylation is the process of post-translational modification of target proteins which may affect the crucial process of the plant growth and development. Among different plant growth and development processes, one of the remarkable roles of SUMO is a rapid defense against environmental challenges such as drought, cold, heat, nutrient deficiency, heavy metals, and salt stresses. Recently, studies have explored the additional roles of SUMO at the time of flowering, cellular growth and development processes, defense against pathogen infection and infestation. This review aims to critically present the current findings on roles and mechanisms involved in the regulation of protein SUMOylation. In summary, this review provides an overview of molecular mechanism of SUMOylation to defend and cope with abiotic stresses and to stabilize the normal growth and development of the plant.

植物非生物胁迫中的 SUMO 和 SUMOylation

翻译后修饰是大多数细胞信号事件的根本原因。植物在不同的环境胁迫下表现出细致的反应。SUMOylation 是重要的翻译后修饰之一。翻译后修饰剂在改变蛋白质稳定性、蛋白质之间的相互作用和蛋白质的最终命运方面发挥着重要作用。为了加快植物抵御环境压力，小泛素样修饰剂 (SUMO) 与细胞内蛋白质的结合是至关重要的过程。蛋白质异构体的数量在相扑过程中的相扑化和去相扑化反应中起着重要作用。SUMOylation 是靶蛋白翻译后修饰的过程，可能影响植物生长发育的关键过程。在不同的植物生长和发育过程中，SUMO 的显着作用之一是快速防御干旱、寒冷、炎热、营养缺乏、重金属和盐胁迫等环境挑战。最近，研究探索了 SUMO 在开花、细胞生长和发育过程、防御病原体感染和侵染时的其他作用。本综述旨在批判性地介绍当前关于蛋白质 SUMO 化调节所涉及的作用和机制的发现。总之，
