GST — Cicer arietinum

Summary

LOC101508320, designated CaGST and located on chickpea chromosome 3, encodes a glutathione S-transferase (GST) of the GSTL1/2/3 family. The enzyme possesses glutathione transferase and dehydroascorbate reductase activities. CaGST is associated with the ascorbate-glutathione cycle, protein glutathionylation, cellular oxidant detoxification, and glutathione metabolism. It is linked to responses to abscisic acid, auxin, cytokinin, gibberellin, heat, and metals, as well as to defense responses and positive regulation of salicylic acid-mediated signaling. The gene is associated with seed development and seed size. The protein localizes to the cytosol, cytoplasm, and plasmalemma. Studies of related genes in other species link the GSTL family to drought tolerance, leaf chlorosis, stomatal resistance, and anthocyanin content.
