Molecular Characterization of Species of the Subgenus from Myanmar.

The species composition and genetic diversity of the subgenus in Myanmar are not yet fully understood. In this study, mice were trapped in rural areas near the Ayeyarwady River basin, spanning five Myanmar cities from north to south: Mandalay, Bagan, Magway, Pyay, and Yangon. Mitochondrial cytochrome () and nuclear melanocortin 1 receptor () gene sequences were determined for mice sampled and revealed a widespread occurrence of in central Myanmar in addition to its previously known occurrence in the Yangon district of southern Myanmar.

Mus lepidoides (Muridae, Rodentia) of central Burma is a distinct species of potentially great evolutionary and biogeographic significance.

Mus lepidoides of central Burma (Myanmar) was described 75 years ago but has since been dismissed as a regional variant of the Indian field mouse, M. booduga. DNA sequences of multiple mitochondrial and nuclear genes from recently collected specimens, combined with a fresh morphological reassessment, reaffirm the distinctiveness of M.

Comparative analysis of evolutionary modes in Mc1r coat color gene in wild mice and mustelids.

Sequences from ten species of Mus (Rodentia, Muridae) of the melanocortin-1 receptor (Mc1r) gene (945 bp), which plays a key role in coat color determination, were compared with an existing Mc1r dataset (ca. 498 bp) from 12 species of Mustela and Martes (Carnivora, Mustelidae). The dN/dS ratio (omega) was estimated at 0.

Temporal, spatial, and ecological modes of evolution of Eurasian Mus based on mitochondrial and nuclear gene sequences.

We sequenced mitochondrial (cytochrome b, 12S rRNA) and nuclear (IRBP, RAG1) genes for 17 species of the Old World murine genus Mus, drawn primarily from the Eurasian subgenus Mus. Phylogenetic analysis of the newly and previously available sequences support recognition of four subgenera within Mus (Mus, Coelomys, Nannomys, and Pyromys), with an unresolved basal polytomy. Our data further indicate that the subgenus Mus contains three distinct 'species groups': (1) a Mus booduga Species Group, also including Mus terricolor and Mus fragilicauda (probably also Mus famulus); (2) a Mus cervicolor Species Group, also including Mus caroli and Mus cookii; and (3) a Mus musculus Species Group, also including Mus macedonicus, Mus spicilegus, and Mus spretus.
