한국산 맹꽁이의 미토콘드리아 Cytochrombe b 유전자의 유전적 변이 = Genetic Variation of Mitochondrial Cytochrome b Gene of Karoula borealis (Amphibia ; Microhylidae)

다국어 초록 (Multilingual Abstract)

The nucleotide sequences of 420 bp segment of cytochrome (cyt) b gene were analyzed using 14 specimens from Korea and 2 specimens from China. The level of mitochondrial DNA sequence differences ranged from 0% to 0.48% among seven popul-ations of Korean K. borealis, and 0.72% to 0.97% among Korean and Chinese K. borealis. In Korean K. borealis, the nucleotide substitution rates were ranged from 0% to 0.71% and all the nucleotide substitutions occurred by transition. Using Tamura-Nei distance, the level of sequence divergence ranged from 0.71% to 1.43% between Korean and Chinese K. borealis. According to the sequence divergence, the genetic variation among Korean and Chinise populations of K. borealis is very low. In the neighbor-joining tree, all the K, borealis samples were grouped in one.
