Complete mitochondrial genomes of the North American collared lemmings Traill, 1823 and Pallas, 1778 (Rodentia: Arvicolinae).

The complete mitochondrial genomes of two species of the North American collared lemmings were obtained by using PCR amplification and capillary sequencing (GenBank accession nos. KX712239 and KX683880). The collared lemming mitochondrial genomes are 16,341 and 16,338 base pairs long and show the gene order, contents and gene strand asymmetry typical for mammals. The mitogenome sequences provide an important genomic resource for the collared lemmings, which are model study species in Arctic genetic diversity and biogeographic history.
