GST — Beta vulgaris subsp. vulgaris

Summary

BVRB_7G165490 (symbol GST, preferred name BvGST) on sugar beet chromosome 7 encodes a glutathione S-transferase (GST) with glutathione transferase activity, belonging to the Tau and Omega/Tau-like subfamilies. The gene is associated with detoxification, glutathione metabolism, pectin metabolism, toxin breakdown, melatonin anabolism, and autotrophy. It is linked to responses to abscisic acid, auxin, cytokinin, gibberellin, heat, and metal stress, as well as defense responses. Localized to the cytoplasm, BvGST is also associated with quantum yield, starch content, photosynthetic rate, and chlorophyll content. Studies of related genes in other species link the family to chilling stress response, drought tolerance, oxidative stress response, and pathogen defense, though these associations are not yet established for this sugar beet gene.
