Molecular authentication of the Eospalax of Myospalax by analyzing cytochrome b sequences

摘要

Nucleotide Complete sequences of mitochondrial DNA ( mtDNA) cytochrome b gene ( 1140 bp) were used to determine the phylogenetic relationships among 21 samples of subgenus Eosp alax o f Myospalax genus from 11 different places of Gansu province, other sequences were acquired from GenBank.Four species from Gan su included Qin ling zokor ( Eospalax ru f escens),Gansu zokor ( M.cansu ),Bailey's zokor ( M.baileyi), and Smith's zokor ( M.smithi).The phylogenetic tree was constructed from the 43 near complete cyt b sequences.The sequences and UPGMA tree are integrity and credibility in our study, then he origin and evolution of subgenus Eosp alax from molecular level were illustrated firstly in Gansu province.
