SHD — Brassica napus

Summary

BnSHD (DARMORV10_A08P21570.1) on chromosome A08 of oilseed rape encodes a member of the heat shock protein 90 family, containing Hsp90_N, Hsp90_C and HATPase 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 localises to the ER lumen, Golgi complex, plasmodesmata, and plant-type vacuole. Associations with agronomic traits include floral organ morphology, seed set percent, seed viability, pollen fertility, days to flowering, drought tolerance, nitrogen content, root development, and insect damage response. Studies of related genes in other species link the family to thermotolerance, salt tolerance, endoplasmic reticulum function, and telomere length regulation.
