HSP70 — Camelina sativa

Summary

CsHSC70-7 (CSA02G037270) on Camelina sativa chromosome 2 encodes a heat shock protein 70 (HSP70) family chaperone with ATP hydrolase activity, protein folding chaperone function, and additional annotated molecular functions including ethene binding, histidine kinase activity, SUMO transferase activity, and kinase binding. The gene 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 signalling. It is linked to responses to heat, salt, and hypoxia, as well as pollen germination and development, embryo development, and seed dormancy. Associations with agronomic traits include leaf position, stem elongation, stomatal resistance and opening, trichome morphology, leaf senescence, seed growth, flowering time, root morphology, abscisic acid sensitivity, and salt tolerance. The protein localises to the ER lumen, plastid stroma, thylakoid, chloroplast envelope, and apoplast. Related genes in other species link the family to thermotolerance, osmotic stress tolerance, ROS scavenging, and chloroplast development.
