| Abstract: | In order to study Mongolian sheep Brachyury gene DNA sequence, main purpose of this article by using the method of PCR, DNA sequence of Mongolian sheep Brachyury gene cloning and the complete Brachyury gene sequences were obtained for the first time.The sequencing with NCBI BLAST function on the site, comparing the results with the published sequences of sheep Brachyury homology was as high as 99%.We compared these sequences with ten Brachyury genes of human, mouse and other animals in GenBank database.The results showed that the most sequences were identical.Mongolian sheep Brachyury shared a 96.30% amino acid homology with Bos taurus, the highest degree of homology indicated a close genetic relationship, and the Caudata had the lowest homology 58.45%.It could be further confirmed by phylogenetic analysis.Moreover, the results showed that Mongolian sheep Brachyury gene sequence of amino acids and other vertebrates Brachyury gene sequence of amino acids were highly conservative.The research results showed that Mongolian sheep Brachyury gene sequences and other vertebrates Brachyury gene sequences were highly conservative. |
