Abstract
The mitogenome of the desert toad-headed agama, Phrynocephalus przewalskii, was amplified using polymerase chain reaction (PCR), long-and-accurate PCR and directly sequenced by primer walking. The complete mitogenome was 16,892 bp in size and contained 13 protein-coding, 23 tRNA, and 2 rRNA genes, and 1 control region. The mitogenome of the P. przewalskii was similar to those of other Phrynocephalus sand lizards in gene arrangement and composition, except that tRNA-Phe and tRNA-Pro were exchanged and tRNA-Phe had two copies. The control region comprised three parts, one between tRNA-Thr and tRNA-Phe, a second between the two tRNA-Phe copies, and a third between tRNA-Pro and 12S RNA. The overall nucleotide composition of the H-strand was 36.3% A, 26.7% T, 12.5% G, 24.6% C. The complete mitogenome of P. przewalskii will contribute to understanding the evolution of the genus Phrynocephalus and the family Agamidae.
