Plant aldehyde oxidases (AOs) are multi-functional enzymes, and they could oxidize abscisic aldehyde into ABA (abscisic acid) or indole acetaldehyde into IAA (indoleacetic acid) as the last step, respectively. AOs can be divided into four groups based on their biochemical and physiological functions. In this review, we summarized the recent studies about AOs in plants including the motif information, biochemical, and physiological functions. Besides their role in phytohormones biosynthesis and stress response, AOs could also involve in reactive oxygen species homeostasis, aldehyde detoxification and stress tolerance.
植物醛氧化酶（AOs）是多功能酶，它们可以分别将脱落酸醛氧化为 ABA（脱落酸）或吲哚乙醛氧化为 IAA（吲哚乙酸）作为最后一步。根据其生化和生理功能，AOs 可分为四组。在这篇综述中，我们总结了植物中 AOs 的最新研究，包括基序信息、生化和生理功能。除了在植物激素生物合成和应激反应中的作用外，AOs 还可能参与活性氧平衡、醛解毒和应激耐受。
