AO1 — Pisum sativum

Summary

PsAO1 (PSAT0S2541G0120) encodes a protein with aldehyde oxidase, abscisic aldehyde oxidase, aryl-aldehyde oxidase, xanthine dehydrogenase, and indole-3-acetaldehyde oxidase activities, containing molybdenum cofactor-binding, FAD-binding, and 2Fe-2S cluster-binding domains. In garden pea, this gene is associated with abscisic acid and auxin biosynthesis, glucosinolate metabolism, nitrogen fixation, seed development, cellular response to aldehyde, virus-induced PTGS, and response to hydrogen peroxide. It is linked to phytohormone biosynthesis, leaf senescence, ABA biosynthesis, seed germination, stomatal movement, drought and salt stress responses, pathogen resistance, chlorophyll degradation, and reactive oxygen species production. The product localizes to plastid, cytosol, and nucleus. Studies of related genes in other species link the family to water balance homeostasis, drought tolerance, stomatal closure, basal defense, and indolic defence compound biosynthesis.
