The sequence and characterization of mitochondrial of Lepus oiostolus (Lagomorpha: Leporidae)

The mitochondrial genome sequence of Manchurian Hare (Lepus mandshuricus)

The Manchurian hare (Lepus mandshuricus) is widely distributed in eastern Russia and northeastern China, but due to limited research, its taxonomic status remains somewhat ambiguous. The mitochondrial genome of the Manchurian hare was 16,705 bp in length, which was consisted of 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and one control region. The overall nucleotide composition is 31.7% A, 29.4% T, 13.3% G, and 25.6% C, indicating a high AT content. Phylogenetic analysis reveals a closer relationship of the Manchurian hare with the Korean hare (Lepus coreanus) and the Iberian hare (Lepus granatensis), while its relationship with the Hainan rabbit (Lepus hainanus), European hare (Lepus europaeus) and the snowshoe hare (Lepus americanus) is more distant. The mitochondrial genome of the Manchurian hare is of vital importance for the phylogenetic analysis of lagomorphs and provides valuable data for deeper evolutionary inquiries.

Characterization of a complete mitochondrial genome of Turdus ruficollis (Passeriformes: Turdidae)

Turdus ruficollis is mainly found in China and Northeast Asia. So far, the mitochondrial genome of more than 20 species from the genus Turdus has been studied. However, the relevant information of T. ruficollis has not been reported. To grasp a better comprehension on the molecular basis of T. ruficollis, we obtained the complete mitochondrial DNA genome sequences of this species. The mitogenome was 16,737 bp in length, which consists of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region. A phylogenetic tree based on complete mitogenome sequences revealed that, within the genus Turdidae, T. ruficollis is closely related to T. naumanni and T. eumomus. The complete mitochondrial genome of T. ruficollis would be of great utility for population genetics and phylogeography of the Turdidae family and would also provide meritorious insights for future studies on conservation, genetics, and phylogeny of the Passeriformes family.
