CYC — Cucumis melo

Summary

MELO3C016630.2 (CYC, CmCYC) on melon chromosome 3 encodes a protein with a Cyt_c-like domain, annotated for electron transfer activity, heme and copper binding. It is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, and with gibberellic acid homeostasis and fruit development. The protein localises to mitochondria, the mitochondrial envelope lumen, the plant-type vacuole, the cytosol and the nucleus. CYC is linked to respiration rate, growth, anther-specific and meristem-specific gene expression, seed germination, respiratory chain function and vascular tissue-specific gene expression. Studies of related genes in other species connect the family to traits including root colour and yield, fruit colour and shape, lycopene and carotenoid content, chlorophyll content, drought tolerance, cytoplasmic male sterility, and delayed growth and flowering.
