HSP70 — Camelina sativa

Summary

CSA18G020440 (HSP70, CsHSC70-7) encodes a member of the Hsp70 family of molecular chaperones, with ATP hydrolase activity, heat shock protein binding, and protein folding chaperone functions. It is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, ERAD pathway, protein-chloroplast targeting, sumoylation, MAPK cascade, brassinosteroid-mediated signalling, and downregulation of ethylene-mediated signalling. The gene is linked to responses to heat, salt, and hypoxia, as well as pollen germination and development, embryo development, and seed growth. Associations with leaf senescence, flowering time, stomatal resistance and opening, root morphology, trichome morphology, stem elongation, abscisic acid sensitivity, and plant stress response traits have been recorded. Localisation evidence connects the product to the ER lumen, plastid stroma, thylakoid, tonoplast, and apoplast. Related genes in other species link the family to thermotolerance, osmotic stress tolerance, ROS scavenging, and chloroplast development.
