SHD — Sorghum bicolor

Summary

SbSHD (SORBI_3010G267400) on sorghum chromosome 10 encodes a heat shock protein 90 (HSP90) family member, containing Hsp90_N, Hsp90_C, and HATPase domains, and is annotated with ATP-dependent protein folding chaperone activity. The gene is associated with diverse biological processes including thylakoid membrane organization, de-etiolation, protein stabilization, defense response to insect, fatty acid beta-oxidation, and telomere maintenance. It is linked to traits such as flowering time, seed set percent, seed viability, pollen fertility, high temperature stress response, and abiotic stress tolerance. Localization evidence connects the product to the chloroplast thylakoid, chloroplast inner membrane, ER lumen, and Tic complex. Studies of related genes in other species link the family to mitochondrial function, thermotolerance, endoplasmic reticulum function, and disease resistance.
