GST — Brassica juncea

Summary

BJUB05G44051S (symbol GST, also known as 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, this gene is associated with pigmentation, anthocyanin and flavonol biosynthesis and transport, proanthocyanidin accumulation, seed color, photomorphogenesis, circadian rhythm, and responses to herbicides, hydrogen peroxide, salicylate, and xenobiotic stimuli. It is also linked to toxin breakdown, glutathione metabolism, secondary metabolism, and sucrose metabolism. The encoded protein localizes to the cytoplasm, nucleus, tonoplast, and macromolecular complexes. Studies of related genes in other species connect the family to seed coat pigmentation, anthocyanin biosynthesis, UV-B tolerance, and altered flavonoid distribution.
