摘　要：摘  要：植物NADPH氧化酶又被称为Rboh(respiratory burst oxidase homologue)，是动物巨噬细胞NADPH氧化酶主要功能亚基gp91phox的同源物。在受到外来信号的刺激时，该酶能通过自身的激活或失活迅速引起活性氧(reactive oxygen species， ROS)的升高或降低，进而在植物生长发育及应答生物或非生物胁迫中发挥重要作用。该文总结了近兼来植物中NADPH氧化酶的结构和功能，以及信号调节机制等方面的研究进展。

Abstract: Abstract: Plant NADPH oxidasetive Enzyme was called Rboh (respiratory burst oxidase homologue)， is a homologue of phagocytic cell gp91phox， the major functional subunit of animal. When exposed to external stimulation signals， the enzyme rapidly increases or decreases reactive oxygen species (ROS) through self-activation or inactivation. Thus Rboh then plays an important role in the biological response and no-living stress in plant. This article which is based on existing new reports searched those related literatures in of recent years both at home and abroad， and briefly introduced the progress in study of its structure and function， as well as regulation mechanism in plants.
Key words: NADPH oxidase; ROS; signal regulation
