CCP3 — Cucumis sativus

Summary

CsCCP3 (CSA_2G360670) on cucumber chromosome 2 encodes a member of the serpin (serine protease inhibitor) family, possessing cysteine-type and serine-type endopeptidase inhibitor activity, protease activity, nutrient reservoir activity, and protein binding. In cucumber, this gene is associated with the photosynthetic electron transport chain, chlorophyll fluorescence, regulation of stomatal closure, brassinosteroid-mediated signalling, defence response to fungi, and protein ubiquitination. It is linked to drought stress response, quantum yield, fruit shape, leaf senescence, seedling growth, root morphology, and salt tolerance. The encoded protein localises to the apoplast, vacuole, Golgi complex, plasmodesma, and stress granules. Studies of related genes in other species connect the family to stress-induced cell death, pathogen resistance, osmotic stress response, and susceptibility to nematodes.
