SHD — Brassica napus

Summary

BnSHD (DARMORV10_C07P53420.1) on chromosome C07 encodes a heat shock protein 90 (HSP90) family member with ATP-dependent protein folding chaperone activity, along with multiple annotated enzymatic functions including CDP-glycerol diphosphatase, 2',3'-cyclic-nucleotide 2'-phosphodiesterase, and acyl-CoA oxidase activities. The gene is associated with diverse biological processes such as long-chain fatty acid metabolism, defense response to insects, ER stress response, telomere maintenance, and regulation of meristem size. It localizes to the ER lumen, Golgi complex, plasmodesmata, and plant-type vacuole. Trait associations include floral organ morphology, seed set percent, seed viability, pollen fertility, drought tolerance, nitrogen content, flowering time, root development, and insect damage response. Related genes in other species link the family to thermotolerance, salt tolerance, endoplasmic reticulum function, and telomere length regulation.
