GST — Beta vulgaris subsp. vulgaris

Summary

BvGST (BVRB_4G077090) on sugar beet chromosome 4 encodes a glutathione S-transferase with glutathione transferase activity, belonging to the Tau and Omega/Tau-like subfamilies. This gene is associated with detoxification, glutathione metabolism, and responses to abscisic acid, auxin, cytokinin, gibberellin, heat, and metal stress. It is linked to defense response, auxin signaling, and processes including pectin metabolism, toxin breakdown, melatonin anabolism, and autotrophy. The encoded protein localizes to the cytoplasm. BvGST has been connected to quantum yield, photosynthetic rate, chlorophyll content, and starch content. Studies of related glutathione S-transferase family members in other species link the family to chilling stress response, drought tolerance, oxidative stress response, and pathogen defense.
