AUR3 — Oryza sativa Japonica

Summary

OS11G0528700 (AUR3, also known as TLD2, OsGH3.11, OsGH3.12, VAS2, OsFIN219, PBS3, OsBRU6) encodes a GH3 family protein with IAA amido synthetase, JA-amino synthetase, and peptide synthase activities, and is annotated as an AMP- and ATP-binding enzyme (EC 6.3.2.-). In rice, this gene is associated with cellular auxin homeostasis, auxin and jasmonic acid anabolism, hormone anabolism, regulation of defence response to bacteria, systemic acquired resistance, photomorphogenesis, response to insects, appressorium formation, secretion, NO storage, embryogenesis, seed development, and sucrose metabolism. It is linked to agronomically important traits including grain yield, tiller angle and number, plant height, harvest index, seed viability and dormancy, chlorophyll content, sugar content, heat tolerance, and salt tolerance. The protein localises to the cytoplasm. Related genes in other species link the family to jasmonic acid conjugation (EC 6.3.2.52).
