Complete mitochondrial genome of Ctenopharyngodon idella var. Gold grass carp and its intraspecific comparison.

We determined the complete mitochondrial genome (Mitogome) of Ctenopharyngodon idella var. gold grass carp (C. idella var.) (Accession No.:KT894100) and compered it with a previously published mitogenome (Accession No.:NC010288.1) of Chinese common grass carp. The total length of mitogenome is 16 609 bp with 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The nucleotide compositions of the L-strand are 31.87% for A, 26.20% for T, 15.68% for G, 26.26% for C. Most of the protein-coding genes began with an ATG start codon except for COX1 and ND3 gene. The sequence similarity was 99.81% between each other. There were 32 variation loci obtained, including of 23 transitions, 7 transversions and 2 INDELs.
