GST — Phaseolus vulgaris

Summary

PvGST (PHAVU_007G162000) encodes a glutathione S-transferase (GST) belonging to the GSTL1/2/3 subfamily, with glutathione transferase activity. This French bean gene on chromosome 7 is associated with protein glutathionylation, detoxification, response to insects, and chlorophyll fluorescence, and is linked to structural organization. The encoded protein localizes to the cytosol, cytoplasm, and plasmalemma. Related genes in other species connect this gene family to leaf chlorosis, stomatal resistance, seed size, anthocyanin content, and drought tolerance, though these associations are not yet established in Phaseolus vulgaris.
