| 摘要 | The whole mitochondrial genomes (mitogenomes) excluding the control region were sequenced for 42 samples of the ten
species of scincid lizards of the genus Plestiodon occurring in Japan, and the mitochondrial genealogy of the East Asian
Plestiodon was reconstructed on the basis of the mitogenomic dataset. A comparison with a species phylogeny based on
five nuclear DNA fragments revealed that P. latiscutatus, a species distributed on the Izu Peninsula of the Japanese Main
Islands, was a sister to the clade consisting of P. japonicus and P. finitimus, species occurring in the remaining parts of
the Main Island in the species phylogeny, whereas the former species was a sister to the P. capito group occurring in
continental China in the mitogenomic phylogeny. A tree reconciliation analysis of the species and the mitochondrial phy-
logenies revealed horizontal transfer of mitochondria, suggesting that the position of P. latiscutatus was caused by past
introgression of mtDNA from the ancestral P. capito group to the ancestral P. latiscutatus. This further suggests a past
long-distance dispersal of the skink from the Eurasian continent to the Izu Peninsula and Izu Islands beyond the western
part of the Japanese Main Islands in the Miocene. |
