SHD — Brachypodium distachyon

Summary

BdSHD (BRADI_1G30130V3) on chromosome 1 of Brachypodium distachyon encodes a member of the Hsp90 family of heat shock proteins, containing Hsp90 and HATPase domains and annotated with ATP-dependent protein folding chaperone activity. The gene is associated with diverse biological processes including vesicle organization, protein secretion, thylakoid membrane organization, chloroplast stroma protein import, de-etiolation, defense response to insects, and fatty acid beta-oxidation. It is linked to numerous traits such as flowering time, seed set, seed viability, pollen fertility, maturity time, root development, plant growth, and responses to high temperature, salt, and bacterial disease. Localization evidence connects the product to the chloroplast inner membrane, thylakoid, nucleoid, ER lumen, and Tic complex. Studies of related Hsp90 genes in other species link the family to thermotolerance, disease resistance, plastid function, and mitochondrial function.
