Characterization and comparison of mitogenomes of three 'eyed' turtles spp.

In this paper, we characterized the mitogenomes of three 'eyed' turtles, the Beal's Eyed turtle (), the Four Eye-spotted turtle (), and the Hainan Four Eye-spotted turtle which was a unique lineage in the four-eyed turtle and considered as an independent species recently. The full lengths of the and mitogenomes are 16,564 bp, and 16,555 bp, respectively, while the length of partial mitochondrial genome of is 16,433 bp without tailed part of D-loop. All the genes exhibit the typical mitochondrial gene arrangement and transcribing directions of turtles. Phylogenetic analysis indicating that a deep divergence about 7.8% p distance was found between and (), and the divergence (2.8% in patristic distance) between and is comparable with other closely related species in turtles.
