Mitochondrial genome of Diploderma micangshanense and its implications for phylogeny of the genus Diploderma.

ABSTRACT

The lizard Diploderma micangshanense, which belongs to the family Agamidae is endemic to China. Here, we determined the complete mitogenome of D. micangshanense using an Illumina Hiseq X Ten sequencer. This mitogenome's structure is a typical circular molecule of 16,467 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. The overall base composition of D. micangshanensis is 34.1% A, 23.64% T, 13.62% C, and 28.64% G with a slight AT bias of 57.74%. Most mitochondrial genes except ND6 and seven tRNAs were encoded on the heavy strand. Notably, the trnP gene was encoded on the heavy strand instead of its typical light strand position, providing an example of gene inversion in vertebrate mitogenomes. Phylogenetic analysis indicated that D. micangshanensis had a close relationship with D. zhaoermii.
