SHD — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0746770 (HvSHD) on barley chromosome 7H encodes a GRP-94 homolog, a member of the heat shock protein 90 (Hsp90) family with ATP-dependent protein folding chaperone activity. The gene is associated with vesicle organization, protein secretion, fatty acid beta-oxidation, sterol anabolism, thylakoid membrane organization, and defense response to insects. It is linked to traits such as flowering time, maturity, seed set, seed viability, pollen fertility, drought sensitivity, high temperature stress response, stem rust response, and chloroplast development. Localization evidence connects the product to the endoplasmic reticulum lumen, chloroplast thylakoid and inner membrane, and the Tic complex. Studies of related genes in other species link the family to thermotolerance, disease resistance, and plastid function.
