CYC — Cucumis sativus

Summary

CsCYC (CSA_5G244150) on cucumber chromosome 5 encodes a cytochrome c family protein with a Cyt_c-like domain, annotated for electron transfer activity, heme and copper binding. The gene is associated with mitochondrial electron transport (both ubiquinol to cytochrome c and cytochrome c to oxygen), mitochondrial fission, regulation of photosynthesis, and ferroptosis. It localises to mitochondria, the mitochondrial envelope lumen, cytosol, nucleus and plant-type vacuole. CsCYC is linked to cytoplasmic male sterility, respiration rate, germination rate, and salt tolerance. Related genes in other species connect the family to traits including drought tolerance, chlorophyll content, fruit colour, lycopene and carotenoid content, root yield, and stress resistance.
