UGT74B1 — Brassica oleracea var. botrytis

Summary

BoUGT74B1 (UGT74B1) on cauliflower chromosome 5 encodes a protein with UDP-glycosyltransferase activity, thiohydroximate beta-D-glucosyltransferase activity, and multiple glucosyltransferase activities toward steviol glycosides, indole-3-acetate, and quercetin. The gene is associated with glucosinolate biosynthesis, accumulation, and desulfoglucosinolate and aromatic glucosinolate synthesis, as well as auxin homeostasis. It is linked to terpene, carotenoid, triterpenoid, saponin, and terpenoid anabolism, detoxification, defense response by callose deposition in cell wall, response to molecule of fungal origin, and defence response to bacteria. The product localizes to the cytosol, cytoplasm, and nucleus. Related genes in other species link the family to auxin content and climate-related traits.
