HSP70 — Brassica oleracea var. botrytis

Summary

BoHSP70 (BOLND125_C01P031030.1_BOLND125_V1) on cauliflower chromosome 1 encodes a heat shock protein 70 family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. The gene is associated with protein import, homologous recombination, sexual reproduction, the ER unfolded protein response, the ERAD pathway, protein refolding, response to virus, response to stress, pollen tube growth, homeostasis, and response to heat. It is associated with heat stress response, thermal stress tolerance, wound response, thermotolerance, abiotic stress response, heat shock response, and radiation response. The encoded protein localises to the ER lumen, ER chaperone complex, cytosol, membrane, Golgi complex, plant-type vacuole, secretory vesicle, and other compartments. Studies of related genes in other species link the family to seed weight, germination rate, chlorophyll content, sugar content, proline content, cadmium concentration, and stomatal resistance.
