The complete mitochondrial genome and phylogenetic analysis of Rhabdophis adleri (Squamata: Colubridae)

Abstract

The study has determined the complete mitochondrial genome sequence of the Rhabdophis adleri. The mitogenome was 17,505 bp in size, containing 26.33% T, 27.08% C, 33.38% A, and 13.21% G, 2 ribosomal RNA (rRNA) genes, 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, as well as 2 Dloop regions. The gene arrangement, nucleotide composition, and the codon usage pattern of the mitochondrial genome of R. adleri were alike in other alethinophidian snakes. The phylogenetic reconstruction analyses yielded similar topologies, having been expressed that R. adleri can strongly be placed within Colubridae.
