SHD — Brassica napus

Summary

BnSHD (DARMORV10_C01P19440.1) on chromosome C01 encodes a heat shock protein 90 (HSP90) family member, specifically an ATP-dependent protein folding chaperone with CDP-glycerol diphosphatase and 2',3'-cyclic-nucleotide 2'-phosphodiesterase activities. The gene is associated with diverse biological processes including long-chain fatty acid metabolism, defense response to insects, ER stress response, and regulation of meristem size and stem cell population maintenance. It localizes to the endoplasmic reticulum lumen, perinuclear cytoplasm, and plasmodesmata. BnSHD has been connected to agronomically important traits such as drought tolerance, nitrogen content, seed set percent, seed viability, pollen fertility, flowering time, root development, and floral organ morphology. Studies of related genes in other species link the family to thermotolerance, salt tolerance, and endoplasmic reticulum function.
