Abstract
This study first report the complete mitochondrial genome sequence of the central chimpanzee, Pan troglodytes troglodytes. The genome was a total of 16 556 bp in length and had a base composition of A (31.05%), G (12.95%), C (30.84%), and T (25.16%), indicating that the percentage of A + T (56.21%) is higher than G + C (43.79%). Similar to other primates, it possessed a typically conserved structure, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 1 control region (D-loop). Most of these genes were found to locate on the H-strand except for the ND6 gene and 8 tRNA genes. The phylogenetic analysis showed that the P. t. troglodytes mitochondrial genome formed a cluster with the other three Pan troglodytes genomes and that the genus Pan is closely related to the genus Homo. This mitochondrial genome sequence would supply useful genetic resources to help the conservation management of primate germplasm and uncover hominoid evolution.
