HSP70 — Cicer arietinum

Summary

LOC101514595 (CaHSP70, HSP70-17) on chickpea chromosome 5 encodes a member of the heat shock 70 family, a chaperone with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. The gene is associated with protein refolding, the ERAD pathway, the unfolded protein response, redox sensing, and DesCEND, as well as starch metabolism, protein synthesis, seed maturation and development, pollen tube growth, and response to heat and stress. It localizes to the ER lumen, ER chaperone complex, tonoplast, plant-type vacuole, Golgi, secretory vesicle, and membrane. CaHSP70 is associated with drought tolerance, seed weight, flavonoid, fructose, and ash content, and with thermotolerance, heat shock, wound, abiotic stress, and radiation responses. Studies of related heat shock 70 family members in other species connect the family to water use efficiency, quantum yield, germination rate, protein content, and dry matter digestibility.
