MITOCHONDRIAL CYTOCHROME B GENE SEQUENCE DIVERSITY IN THE MONGOLIAN RED SQUIRREL, Sciurus vulgaris L.
Journal Title: International Journal of Genetics - Year 2014, Vol 6, Issue 1
Abstract
Red squirrels (Sciurus vulgaris) are widely distributed throughout Eurasia, occurring in many types of coniferous and mixed-deciduous forests. Even though red squirrels are biologically and genetically well-studied worldwide, so far no genetic studies have been conducted in Mongolia. In this paper, complete sequences of the mitochondrial cytochrome b gene of the Mongolian red squirrel (Sciurus vulgaris) were analyzed to determine genetic diversity. Fifteen specimens were collected from seven provinces: Bulgan, Selenge, Tuv, Khuvsgul, Arkhangai, Zavkhan and Bayan-Ulgii. Ten haplotypes were observed from 15 specimens in seven Mongolian provinces, and the maximum Tamura-Nei nucleotide distance among them was 1.1%, indicating that genetic diversity of Sciurus vulgaris is moderate. The population in Khuvsgul showed the highest genetic distance compared to individuals the remaining populations in Mongolia. Further analyses of mtDNA cytochrome b gene with additional specimens of red squirrels from Khuvsgul province are needed to clarify the reason of environmental condition influencing the genetic variation in the squirrel’s population in Khuvsgul.
