Complete mitochondrial genome of Red Junglefowl (Gallus gallus spadiceus) from Peninsular Malaysia

Complete mitochondrial genome sequences have significant relevance in the study of phylogenetic relationships, evolution, and population genetics. In this paper, we present the complete mitochondrial genome of the red junglefowl (Gallus gallus spadiceus) from Peninsular Malaysia, inferred using next-generation sequencing (NGS). The mitogenome is 16,785 bp in length with the structural organization of an avian mitochondrial arrangement compromising 13 protein -coding regions, 22 tRNAs, 2 rRNAs, and 1 control region. No internal stop codon was found in the protein-coding genes. Overall base composition is A: 30.3%, C: 32.5%, G: 13.5%, and T: 23.7%, indicating a high A + T content of 54.0%. Phylogenetic tree analysis revealed that red junglefowl from Peninsular Malaysia is grouped together with other members of Gallus gallus specifically from Southeast Asia, with 89% bootstrap value support. These research findings might be beneficial for red junglefowl genetic identification, molecular systematic studies, and conservation management interest in the future.
