GST8 — Sorghum bicolor

Summary

SORBI_3010G175800 (SbGST8) on sorghum chromosome 10 encodes a glutathione S-transferase (GST) with glutathione transferase and ATP hydrolase activities, belonging to the Tau and Omega-like families. This gene is associated with detoxification processes, including the breakdown of 2,4,6-trinitrotoluene and other toxins, as well as responses to herbicides, drought, and red or far-red light. It has been linked to meristem growth and organization, root and shoot development, inflorescence morphology, and gamete generation. Associations with 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, and apoplast. Studies of related genes in other species connect the family to stress tolerance, including drought, salt, and oxidative stress, as well as herbicide detoxification and root development traits.
