HSP70 — Daucus carota subsp. sativus

Summary

DCAR_025327 (DcHSP70) on carrot chromosome 7 encodes a member of the Hsp70 family of molecular chaperones, possessing ATPase, heat shock protein binding, and protein folding chaperone activities. It is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, sumoylation, homologous recombination, and responses to heat, abscisic acid, and hypoxia. The gene has been linked to brassinosteroid-mediated signalling, embryo development, and downregulation of ethylene signalling. Localisation evidence connects the protein to the ER lumen, plastid stroma, thylakoid, tonoplast, and apoplast. Associations with agronomic traits include photosynthetic rate, stomatal resistance and opening, leaf senescence, flowering time, root morphology, seed growth and development, and abscisic acid sensitivity. Phenotypic associations include thermotolerance, osmotic stress tolerance, chloroplast development, and ROS scavenging.
