GST8 — Sorghum bicolor

Summary

SbGST8 (SORBI_3001G065900) on sorghum chromosome 1 encodes a glutathione S-transferase (GST) with glutathione transferase and ATP hydrolase activities. The gene is associated with detoxification processes, including the breakdown of 2,4,6-trinitrotoluene (TNT) 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 cap development, phyllome and inflorescence development, and male and female gamete generation. Associations with agronomic traits include herbicide sensitivity, zinc sensitivity, chlorophyll content, photosynthetic rate, root and shoot biomass, and disease tolerance. 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 stress tolerance, herbicide detoxification, and root and shoot development.
