Abstract
|
|
|
|
The nucleotide sequence of a 447 base pair fragment in the mitochondrial cytochrome b gene and the complete sequence of the mitochondriat 12S ribosomal RNA gene, 938 bp, were analyzed to infer inter? and intraspecific genetic relationships of Hyla japonica and H. suweonensis from Korea and H. japonica from Japan. In the mitochondrial cytochrome b gene, genetic differentiation among H. japonica populations were 9.62% and 15.66% between H. japonica and H. suweonensis. Based on the Tamura?Nei distance, the level of sequence divergence ranged from 0.45% to 2,75% within Korean H. japonica, while 8.31%?8.87% between Korean and Japanese H. japonica and 11.51 %?12.46% between H. japonica and H. suweonensis. In the neighbor?joining tree, Korean populations of H. japonica were clustered first at 2.22% and followed by Japanese H. japonica and H. suweonensis at 8.51% and 12.29%, respectively. In mitochondrial 12S rRNA gene, genetic differentiation between H. japonica and H. suweonensis was 7,17% (68 bp) including 7 gaps. Based on Tamura?Nei distance, the level of sequence divergence ranged 3.53% between Korean and Japanese H. japonica and from 4.93% to 5.41% between H. japonica and H. suweonensis. Phenogram pattern of the 12S rRNA gene sequence corresponded with that of the mitochondrial cytochrome b gene.
