SHD — Brachypodium distachyon

Summary

BdSHD (BRADI_3G38897V3) on Brachypodium distachyon chromosome 3 encodes a heat shock protein 90 family member with ATP-dependent protein folding chaperone activity. The gene is associated with diverse biological processes including thylakoid membrane organization, chloroplast stroma protein import, vesicle organization, protein secretion, de-etiolation, defense response to insect, and fatty acid beta-oxidation. It has been linked to traits such as flowering time, seed set percent, seed viability, pollen fertility, maturity time, root development, plant growth, and responses to high temperature stress, bacterial disease, and abiotic stress. The product localizes to chloroplast thylakoid and inner membrane, ER lumen, chloroplast nucleoid, and the Tic complex. Studies of related genes in other species connect the HSP90 family to thermotolerance, disease resistance, plastid function, and mitochondrial function.
