CYC — Solanum lycopersicum

Summary

SlCYC (SOLYC01G103220.3) on tomato chromosome 1 encodes a protein with a Cyt_c_1A/1B domain, a cytochrome c-like domain superfamily, and a cytochrome c-like domain, with electron transfer activity, copper binding, heme binding, metal binding, and protein binding. In tomato, SlCYC is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, oxidative phosphorylation, pigment accumulation, carotene anabolism, and fruit color. It is also linked to lycopene and carotenoid content, chlorophyll content, soluble protein and starch content, fruit shape, germination rate, root length, drought tolerance, respiration rate, quantum yield, photochemical quenching, turgor pressure, self-incompatibility, and salt tolerance. The gene localizes to mitochondria, the mitochondrial envelope lumen, the nucleus, cytosol, and plant-type vacuole. Studies of related genes in other species link the family to delayed growth and flowering, stress resistance, and traits including root color, cytoplasmic male sterility, and leaf water potential.
