SHD — Asparagus officinalis

Summary

A4U43_C07F29530, symbol SHD and also known as AoSHD, encodes a heat shock protein 90 family member on asparagus chromosome 7. The product contains Hsp90 and HATPase domains and is annotated with ATP-dependent protein folding chaperone activity, along with numerous other molecular functions including DNA polymerase, transcription regulator, and pectate lyase activities. This gene is associated with diverse biological processes such as cellular response to unfolded protein, brassinosteroid stimulus, and defense response, as well as traits including floral organ morphology, seed set percent, submergence tolerance, bacterial and viral disease response, temperature stress response, and photoperiod-sensitive flowering time. Localization evidence links the product to the chloroplast outer membrane, ER lumen, and plasma membrane periphery. Studies of related genes in other species connect the family to thermotolerance, broad-spectrum disease resistance, salinity tolerance, and developmental regulation.
