SHD — Brassica napus

Summary

BnSHD (DARMORV10_A03P55100.1) on chromosome A03 encodes a heat shock protein 90 (HSP90) family member 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, ER stress response, regulation of meristem size, stem cell population maintenance, and telomere maintenance via telomerase. It has been linked to traits such as floral organ morphology, seed set percent, seed viability, pollen fertility, days to flowering, drought tolerance, nitrogen content, root development, and insect damage response. The encoded protein localizes to the ER lumen, Golgi complex, plasmodesma, and secretory vesicles. Studies of related genes in other species connect the family to thermotolerance, salt tolerance, and endoplasmic reticulum function.
