AO1 — Pisum sativum

Summary

PsAO1 (PSAT2G023520) on garden pea chromosome 2LG1 encodes a protein with aldehyde oxidase, abscisic aldehyde oxidase, aryl-aldehyde oxidase, xanthine dehydrogenase, indole-3-acetaldehyde oxidase, and benzaldehyde dehydrogenase (NAD+) activities, binding molybdenum cofactor, FAD, and 2Fe-2S clusters. It is associated with abscisic acid and auxin biosynthesis, glucosinolate metabolism, nitrogen fixation, seed development, response to hydrogen peroxide and dehydration, virus-induced post-transcriptional gene silencing, and localises to plastid, cytosol, and nucleus. The gene is linked to phytohormone biosynthesis, leaf senescence, ABA biosynthesis, pathogen resistance, seed germination and dormancy, stomatal movement, drought and salt stress responses, chlorophyll degradation, and reactive oxygen species production. Related genes in other species are linked to water balance homeostasis, stomatal closure, basal defense, and drought tolerance.
