Complete mitochondrial genome of the boreal digging frog Kaloula borealis (Anura, Microhylidae)

Abstract

We sequenced the complete mitochondrial genome from the boreal digging frog Kaloula borealis. The genome sequence was 17,173 bp in size, and the gene order and contents were identical to those of previously reported amphibian mitochondrial genomes. Of 13 protein-coding genes (PCGs), 5 genes (CO2, ATPase 6, CO3, ND3, and ND4) had incomplete stop codons. Also ND1 gene used GTG as a start codon, while CO1 and ND5 genes used AGG as a stop codon. The base composition of K. borealis mitogenome showed a strong anti-G bias (6.11%) on the 3rd position of PCGs.
