SHD — Asparagus officinalis

Summary

A4U43_C10F16510 (SHD, AoSHD) on asparagus chromosome 10 encodes a member of the Hsp90 family, containing heat shock protein 90 and HATPase_C domains, and is annotated with ATP-dependent protein folding chaperone activity. The gene is associated with diverse biological processes including cellular response to unfolded protein, response to brassinosteroid stimulus, base-excision repair, vesicle organization, and mitochondrial matrix protein import. It has been linked to numerous traits such as floral organ morphology, seed set percent, submergence tolerance, bacterial and viral disease response, temperature stress response, photoperiod-sensitive flowering time, gibberellin biosynthesis, and starch grain synthesis. Localization evidence connects the product to the chloroplast outer membrane, ER lumen, and perinuclear region. Studies of related genes in other species link the Hsp90 family to thermotolerance, broad-spectrum disease resistance, salinity tolerance, and thylakoid membrane homeostasis.
