AUR3 — Pisum sativum

Summary

PsAUR3 (PSAT2G101440) on garden pea chromosome 2LG1 encodes an indole-3-acetic acid-amido synthetase of the GH3 family, with IAA amido synthetase, JA-amino synthetase, and peptide synthase activities. The gene is associated with auxin metabolism, cellular auxin homeostasis, and auxin transport, as well as regulation of defence response to bacteria, defence response, response to auxin, response to light stimulus, and pollen development. The encoded protein localises to both the cytoplasm and nucleus. PsAUR3 is associated with root growth under ammonium stress, apical dominance, hypocotyl elongation, salinity tolerance, root elongation, ammonium tolerance, root architecture, auxin homeostasis, water deficit tolerance, and abiotic stress response. Related genes in other species are linked to auxin conjugation, adventitious root initiation, and root growth.
