GST — Phaseolus vulgaris

Summary

PvGST (PHAVU_001G173500) on French bean chromosome 1 encodes a glutathione S-transferase (GST) belonging to the GSTL1/2/3 subfamily, with glutathione transferase activity. This cytosolic and plasma-membrane-associated protein is associated with protein glutathionylation, glutathione metabolism, detoxification, defense response, response to insect, auxin signaling, chlorophyll fluorescence, and structural organization. Related genes in other species link the family to leaf chlorosis, stomatal resistance, seed size, anthocyanin content, and drought tolerance, though these associations are not yet established for PvGST itself.
