GST — Brassica juncea

Summary

BJUA02G36770S (symbol GST, preferred name BjTT19) encodes a glutathione S-transferase (GST) of the Phi class, possessing glutathione transferase activity, glutathione binding, cation binding and protein homodimerization activity. In Indian mustard (Brassica juncea), this gene is associated with the regulation of flavonol biosynthetic process, pigmentation, photomorphogenesis, circadian rhythm, and responses to xenobiotic stimulus, herbicide, hydrogen peroxide, and salicylate. It is linked to seed color, anthocyanin accumulation, proanthocyanidin accumulation, flavonol content, and anthocyanin transport. The encoded protein localises to the cytoplasm, nucleus, tonoplast, and macromolecular complex. Studies of related genes in other species connect the family to seed coat pigmentation, anthocyanin biosynthesis, UV-B tolerance, and altered flavonoid distribution.
