CYTC-1 — Brassica napus

Summary

BnCYTC-1 (CYTC-1) on chromosome A07 of oilseed rape (Brassica napus) encodes a cytochrome c family protein containing a Cyt_c-like domain and a Cyt_c-1A/1B domain. The gene product is annotated with electron transfer activity, copper binding, heme binding, and protein binding, and is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, as well as mitochondrial biogenesis, gibberellic acid homeostasis, nitric oxide storage, and response to cold. It localises to mitochondria, the mitochondrial envelope lumen, the plant-type vacuole, the cytosol, and the nucleus. The gene has been linked to linolenic acid content, cytoplasmic male sterility, drought tolerance, growth, and anther- and meristem-specific gene expression. Studies of related genes in other species connect the family to amino acid content, heterosis, and stress resistance.
