GST — Beta vulgaris subsp. vulgaris

Summary

BvGST (BVRB_3G069410) on sugar beet chromosome Bvchr3_un.sca008 encodes a glutathione S-transferase (GST) with glutathione transferase activity, belonging to the Tau class (GST_C_Tau, Omega/Tau-like) and containing thioredoxin-like and glutathione S-transferase domains. This gene is associated with detoxification, glutathione metabolism, and toxin breakdown, as well as responses to abscisic acid, auxin, cytokinin, gibberellin, heat, and metals. It is associated with auxin signaling, defense response, pectin metabolism, melatonin anabolism, and autotrophy. The product localizes to the cytoplasm. Associations with photosynthetic rate, chlorophyll content, quantum yield, and starch content have been noted. Studies of related genes in other species link the family to drought tolerance, chilling stress response, oxidative stress response, and pathogen defense.
