摘　　要：去泛素化酶作为泛素系统中一类重要的蛋白质水解酶,具有逆转泛素化的作用。目前研究发现去泛素化酶具有复杂的生物学调控功能,能调节细胞内众多蛋白底物的稳定性和功能,参与了生物体内细胞周期调控、细胞分裂与分化、DNA损伤修复、生长发育和逆境胁迫响应等多方面的生理活动。本文主要综述了去泛素化酶在植物中的调控作用,包括调控植物生长和发育、植物对环境的免疫应激反应和介导多种信号转导途径等三个方面。Deubiquitinating enzymes（DUBs） are the class of proteases that serve to reverse the modification of proteins by ubiquitin. By modulating the stabilities and activities of cellular proteins, DUBs play multiple key roles in the regulation of various cellular processes, including cell cycle control, cell mitosis, cell differentiation, DNA damage repair, growth and development and stress response. In this review, we summarized the roles that plant DUBs play in three fields： plant growth and development, immune response and signal transduction. This will provide some reference for further study of plant DUBs.
