SHD — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0488480, designated HvSHD on barley chromosome 5H, encodes a member of the Hsp90 family of ATP-dependent protein folding chaperones, also annotated with CDP-glycerol diphosphatase, 2',3'-cyclic-nucleotide 2'-phosphodiesterase, and pectate lyase activities. The gene is associated with vesicle organization, long-chain fatty acid metabolism, protein secretion, defense response to insects, de-etiolation, thylakoid membrane organization, and positive regulation of telomere maintenance. It is linked to maturity time, stem rust response, drought sensitivity, seed viability, pollen fertility, flowering time, root development, and seed set percent. Localization evidence connects the product to the chloroplast thylakoid, ER lumen, Tic complex, and secretory vesicles. Related genes in other species link the Hsp90 family to thermotolerance, disease resistance, grain weight, and chloroplast function.
