CYC — Beta vulgaris subsp. vulgaris

Summary

BvCYC (BVRB_9G222490) on sugar beet chromosome 9 encodes a cytochrome c family protein with electron transfer activity, copper and heme binding, and is localized to mitochondria, the mitochondrial envelope lumen, the nucleus, cytosol, and plant-type vacuole. It is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, as well as gibberellic acid homeostasis, protein folding, translation initiation, and lipid and carbohydrate metabolism. The gene has been linked to root yield, root length, chlorophyll content, stomatal resistance, respiration rate, and salt tolerance, along with phenotypes including seed germination, growth, respiratory chain function, and anther-, meristem-, and vascular tissue-specific expression. Studies of related genes in other species connect the family to traits such as drought tolerance, stress resistance, carotenoid content, and fruit and root color.
