Research progress of aldehyde oxidases in plants

PeerJ. 2022 Mar 25:10:e13119. doi: 10.7717/peerj.13119. eCollection 2022.

Abstract

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.

Keywords: Abscisic acid; Aldehyde oxidases; Indoleacetic acid; Stress.
