Abstract

In this study, we sequenced the complete mitochondrial genome (mitogenome) of the Thai Red Junglefowl (RJF; Gallus gallus) using the next-generation sequencing (NGS) platform of the Ion Torrent PGM. Samples were taken from Mae Wang District, Chiang Mai Province, northern Thailand. Our data showed the complete mitogenome to be 16 785 bp in length, composed by 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region. The genome nucleotide composition was 30.3% A, 23.7% T, 32.5% C, and 13.5% G, resulting in a high percentage of A+T (50.4%). Phylogenetic analysis revealed that the mitogenome belonged to haplogroup X, whereas those of all domestic chickens belong to haplogroups A to G. This newly released mitogenome sequence will advance further evolutionary and population genetics study of the RJF and domestic chicken. The availability of the G. gallus mitogenome will also contribute to further conservation genetics research of a unique species, listed as ‘data deficient’ in Thailand.
