SHD — Brassica oleracea

Summary

BoSHD (BOLC102_C08P018370.1_BOLC102_V1) on cabbage chromosome 8 encodes a heat shock protein 90 (HSP90) family member, specifically an ATP-dependent protein folding chaperone. The gene is associated with diverse biological processes including protein secretion, fatty acid beta-oxidation, defense response to insects, telomere maintenance, and regulation of meristem size. It localizes to the endoplasmic reticulum lumen, Golgi complex, plasmodesmata, and secretory vesicles. BoSHD has been linked to agronomically important traits including floral organ morphology, seed set percent, seed viability, pollen fertility, drought tolerance, sugar content, cadmium concentration, proline content, days to flowering, root development, and insect damage response. Studies of related genes in other species connect the family to thermotolerance, salt tolerance, endoplasmic reticulum function, and telomere length regulation.
