CYC — Daucus carota subsp. sativus

Summary

DCAR_009275 (CYC, DcCYC) on carrot chromosome 3 encodes a cytochrome c-like domain protein with electron transfer activity, copper and heme binding, and protein binding. It is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, as well as with flower formation, morphogenesis, developmental processes, gibberellic acid homeostasis, carotenoid anabolism, response to hormone, and sensitization. The gene is linked to root color, respiration rate, growth, seed germination, anther- and meristem-specific gene expression, and respiratory chain function. It localizes to mitochondria, the mitochondrial envelope lumen, the nucleus, cytosol, and plant-type vacuole. Studies of related genes in other species connect the family to root yield, lycopene and carotenoid content, fruit color, drought tolerance, and delayed growth and flowering.
