GST8 — Sorghum bicolor

Summary

SbGST8 (SORBI_3002G173200) on sorghum chromosome 2 encodes a glutathione S-transferase (GST) of the Tau class, with glutathione transferase activity and glutathione binding capacity. This gene is associated with detoxification processes, including the breakdown of 2,4,6-trinitrotoluene and other toxins, as well as responses to herbicides and drought. It has been linked to meristem growth and structural organization, root cap development, phyllome and inflorescence development, and both male and female gamete generation. Associations with traits include herbicide sensitivity, zinc sensitivity, chlorophyll content, photosynthetic rate, root and shoot biomass, and disease tolerance. The gene product localizes to multiple cellular compartments, including the cytosol, chloroplast stroma, mitochondria, apoplast, and proteasome. Studies of related genes in other species link the family to stress tolerance, xenobiotic detoxification, and herbicide response.
