HSP70 — Capsicum annuum

Summary

CaHSP70 (T459_32464) encodes a heat shock 70 kDa protein 7, chloroplastic, a member of the Hsp70 chaperone family with ATP hydrolase activity and protein folding chaperone activity. In pepper, it is associated with ethene binding, histidine kinase activity, SUMO transferase activity, and protein refolding. The gene is linked to the ERAD pathway, sumoylation, ABA and brassinosteroid signalling, and responses to heat, hypoxia, and stress. It has been connected to fruit length, plant height, photosynthetic rate, stomatal resistance, leaf senescence, flowering time, seed growth and development, root morphology, and abscisic acid sensitivity. Associations include chloroplast development, thermotolerance, ROS scavenging, osmotic and heat stress tolerance, ethylene sensitivity, and viral resistance. Studies of related genes in other species link the family to protein import into chloroplasts, seed germination, and ethylene perception.
