Complete mitochondrial genome of the Greenland wolf, Canis lupus orion

Abstract

The Greenland wolf, Canis lupus orion as s subspecies of the gray wolf, is native to Greenland. Here, we assembled a complete 16,650 bp genome for the C. l. orion mitochondrion by employing Illumina HiSeq platform. The complete mitochondrial genome contained 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and one control region. Overall DNA sequence of the C. l. orion mitochondrion was identical to that of gray wolf C. l. lupus, although slight difference was observed in their control regions. The genomic structure of C. l. orion mitochondrion was conserved with the gene arrangements of mitogenomes published in Canidae, and phylogenetic analysis confirmed the sister relationship among Canis sp. This information will provide essential molecular reference to elucidate biogeography, phylogenetic distance, and evolutionary history in gray wolves.
