The complete mitochondrial genome of Microhyla butleri (Amphibia, Anura, Microhylidae)

The complete mitochondrial genome was determined from a Microhyla butleri, Microhylidae, Microhyla, which was collected from Shenzhen, China. The mitogenome was 16 714 bp in length, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region (D-loop). The base composition was 28.7% A, 29.5% T, 27.2% C and 14.6% G. The gene order and contents were identical to most amphibian mitogenome. Except ND1 gene beginning with GTG and COI gene beginning with ATA, all other protein-coding genes began with ATG as start codon. Six protein-coding genes (ND1, COII, ATP6, COIII, ND3 and ND4) ended with incomplete stop codon T. The 22 tRNA genes with the size ranging from 65 bp to 74 bp were interspersed along the whole genome. The D-loop region containing tandem repetition was 1334 bp in length and heavily biased to A + T nucleotides.
