Genetic characterization of Meigu goat (Capra hircus) based on the mitochondrial DNA

摘要

Meigu goat (Capra hircus) is one of the indigenous goat breeds in China. Our research findings revealed that the entire mitochondrial genome of Meigu goat was 16;643 bp in length. The contents of A, C, T and G in the mitochondrial genome were 33.59%, 26.05%, 27.31% and 13.05%, respectively. The mitogenome of meigu goat contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region. Components of the Meigu goat's mitogenome were similar to those of other Capra hircus in gene arrangement and composition. These results could provide essential information for molecular phylogenetic and evolutionary analyses of domestic goats.
