GST8 — Zea mays

Summary

ZmGST8 (GST8) on maize chromosome 1 encodes a glutathione S-transferase (GST) with glutathione transferase activity, glutathione binding, and ATP hydrolase activity, belonging to the Tau and Omega/Tau-like GST families. The gene is associated with diverse biological processes including response to chemicals, salicylic acid metabolism, downregulation of photosynthesis, ear development, and nitrogen fixation. It is linked to traits such as spike weight, mesocotyl and coleoptile length, root branching, herbicide and zinc sensitivity, cold tolerance, chlorophyll content, photosynthetic rate, and disease tolerance. Localisation evidence connects the product to the cytosol, chloroplast stroma, mitochondria, apoplast, and proteasome. Studies of related genes in other species associate the family with herbicide detoxification, oxidative stress tolerance, and salt tolerance.
