CYC — Solanum tuberosum

Summary

StCYC (PGSC0003DMG400001003) on potato chromosome 11 encodes a cytochrome c family protein with a Cyt_c-like domain, possessing electron transfer activity, heme and copper binding, and protein binding. It is associated with mitochondrial electron transport from ubiquinol to cytochrome c and cytochrome c to oxygen, as well as alternative respiration, energy homeostasis, fermentation, and carbohydrate breakdown. The gene is linked to anammox, hormone secretion, microtubule dynamics, anti-apoptosis, and response to water. Localisation evidence places the product in mitochondria, the mitochondrial envelope lumen, cytosol, nucleus, and plant-type vacuole. Associations with agronomic traits include leaf water potential, root hair density, respiration rate, starch content, protein content, and chlorophyll content. Phenotype connections involve growth, seed germination, respiratory chain function, and anther-, meristem-, and vascular tissue-specific expression. Studies of related genes in other species link the family to drought tolerance, stress resistance, root yield, and carotenoid content.
