HSP70 — Cucumis melo

Summary

MELO3C020341.2 (CmHSP70) on melon chromosome 6 encodes a member of the Hsp70 family of molecular chaperones, possessing ATP hydrolase activity, heat shock protein binding, and protein folding chaperone functions. It is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, sumoylation, and responses to heat, abscisic acid, and hypoxia. The gene has been linked to pollen germination and development, embryo development, and brassinosteroid-mediated signaling. Associations with agronomic traits include photosynthetic rate, stomatal resistance and opening, leaf senescence, flowering time, seed growth and development, root morphology, stem elongation, trichome morphology, and abscisic acid sensitivity. Phenotypic connections include thermotolerance, osmotic and salt stress tolerance, chloroplast development, and ROS scavenging. Related genes in other species link the family to ethylene signaling, perception, and sensitivity, as well as leaf senescence and disease symptom development.
