HSP70 — Pisum sativum

Summary

PSAT1G222760 (HSP70, PsHSC70-7) on chromosome 1LG6 encodes a member of the Hsp70 family, a heat shock 70 kDa chaperone with ATPase activity, heat shock protein binding, and protein folding chaperone functions. It is associated with protein import into mitochondria and chloroplasts, protein folding in the endoplasmic reticulum, ERAD pathway, S-nitrosylation, and iron-sulfur cluster assembly. The gene has been connected to thermotolerance, heat and osmotic stress tolerance, ROS scavenging, chloroplast development, and seed maturation. Associations also include leaf senescence, stomatal resistance and opening, abscisic acid sensitivity, flowering time, root morphology, stem elongation, and trichome morphology. Studies of related genes in other species link the family to ethylene perception, protein import into chloroplasts, seed germination, embryo viability, and microtubule assembly.
