AO1 — Pisum sativum

Summary

PsAO1 (PSAT0S2541G0080) encodes a protein with aldehyde oxidase, abscisic aldehyde oxidase, aryl-aldehyde oxidase, xanthine dehydrogenase, and indole-3-acetaldehyde oxidase activities, binding FAD, molybdenum cofactor, and 2Fe-2S clusters. In garden pea, this gene is associated with abscisic acid and auxin biosynthesis, glucosinolate metabolism, nitrogen fixation, seed development, response to hydrogen peroxide and dehydration, and virus-induced post-transcriptional gene silencing. It is linked to leaf senescence, stomatal movement, seed germination and dormancy, pathogen resistance, salt and osmotic stress responses, chlorophyll degradation, and reactive oxygen species production. The protein localizes to plastids, cytosol, and nucleus. Studies of related genes in other species connect the family to drought tolerance, stomatal closure, and basal defense.
