SHD — Brassica napus

Summary

BnSHD (DARMORV10_A01P15520.1) on chromosome A01 encodes a heat shock protein 90 family member, containing Hsp90, HATPase and ribosomal domains, and is annotated with ATP-dependent protein folding chaperone activity. The gene is associated with diverse biological processes including long-chain fatty acid metabolism, defense response to insects, sterol anabolism, telomere maintenance, regulation of meristem size, stem cell population maintenance, and ER stress response. It localizes to the endoplasmic reticulum lumen, Golgi complex, plasmodesmata, and secretory vesicles. Trait associations include floral organ morphology, seed set percent, seed viability, pollen fertility, days to flowering, drought tolerance, root development, nitrogen content, and insect damage response. Related genes in other species link the family to thermotolerance, salt tolerance, endoplasmic reticulum function, and telomere length regulation.
