GST8 — Sorghum bicolor

Summary

SbGST8 (SORBI_3002G361100) on sorghum chromosome 2 encodes a glutathione S-transferase (GST) with glutathione transferase activity, glutathione binding, and ATP hydrolase activity, belonging to the Tau and Omega-like subfamilies. The gene is associated with detoxification processes, including 2,4,6-trinitrotoluene and herbicide breakdown, as well as cellular responses to drought, gravity, and red or far-red light. It has been linked to meristem growth and organization, root cap development, phyllome and inflorescence development, and male and female gamete generation. Associations with agronomic traits include herbicide sensitivity, zinc sensitivity, photosynthetic rate, chlorophyll content, disease tolerance, and root and shoot biomass. The protein localizes to multiple cellular compartments, including the cytosol, chloroplast stroma, mitochondria, apoplast, and proteasome. Studies of related genes in other species connect the family to drought and salt tolerance, oxidative stress resistance, and herbicide detoxification.
