AUR3 (TRAESCS2A02G137800) — triticum aestivum

Summary

TRAESCS2A02G137800 (TaAUR3) on wheat chromosome 2A encodes a GH3 family protein with IAA amido synthetase, peptide synthase, and jasmonate-amino synthetase activities, along with adenylyltransferase, AMP binding, and amino acid binding functions. The gene is associated with auxin and jasmonic acid metabolism, cellular auxin homeostasis, camalexin anabolism, anthocyanin metabolism, and regulation of defence response to bacteria. It is linked to grain yield, photosynthetic ability, photoperiod sensitivity, photoperiod-sensitive flowering time, plant growth hormone response, branch angle, panicle number, root architecture, and responses to red, far-red, and blue light. Localisation evidence connects the product to the chloroplast envelope, vacuole, plasmodesma, mitochondria, cytosol, and plasmalemma. Studies of related genes in other species link the family to auxin conjugation, pathogen response, root growth, and abiotic stress tolerance.
