Complete sequence cloning and bioinformatics analysis of the chukar partridge (Alectoris chukar, Aves, Galliformes) in Guangxi base on mitochondrial genome

The objective of this study was to obtain the complete mitochondrial DNA sequence of chukar partridge, and to provide reference data for protection and utilization of these resources of chukar partridge. The complete mitochondrial genome sequence of the China chukar partridge was measured by PCR-based methods and analysed in detail. Our research findings reveal that the entire mitochondrial genome of the chukar partridge is a circular molecule consisting of 16,688 bp (GenBank accession number: KY829450). The contents of A, T, C, and G in the mitochondrial genome were found to be 30.44%, 24.43%, 31.57%, and 13.56%, respectively. The complete mitochondrial genome of the chukar partridge has a typical structure, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region (D-loop region). This complete mitochondrial genome sequence provides essential information in understanding phylogenetic relationships among Galliformes mitochondrial genomes.
