HSP70 — Daucus carota subsp. sativus

Summary

DCAR_013333 (DcHSP70, HSP70-17) on carrot chromosome 4 encodes a heat shock 70 kDa protein with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It is associated with the ER chaperone complex, ER lumen, chloroplast membrane, tonoplast, Golgi, and secretory vesicles. The gene is associated with protein folding in the ER, ERAD pathway, ER unfolded protein response, homologous recombination, response to heat, stress, virus, and pollen tube growth. Associations include thermotolerance, heat stress response, wound response, abiotic stress response, and photosynthetic rate. Studies of related genes in other species link the family to heat tolerance in tomato, drought and salt stress tolerance in sugar beet, and associations with traits including plant height, seed weight, chlorophyll content, germination rate, and fruit size.
