CYTC-1 — Brassica napus

Summary

BnCYTC-1 (CYTC-1) on chromosome C07 of oilseed rape (Brassica napus) encodes a cytochrome c family protein containing a Cyt_c-like domain, with electron transfer activity, copper and heme binding, and protein binding functions. The gene is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, mitochondrial biogenesis, gibberellic acid homeostasis, nitric oxide storage, and response to cold. It localises to mitochondria, the mitochondrial envelope lumen, plant-type vacuoles, cytosol, and nucleus. Associations include linolenic acid content, cytoplasmic male sterility, drought tolerance, growth, and anther- and meristem-specific gene expression. Studies of related genes in other species link the family to amino acid content, heterosis, plant stress response, delayed growth and flowering, and stress resistance.
