Phylogenetic implications of jungle crow Corvus macrorhynchos and carrion crow Corvus corone based on base sequence of mitochondrial DNA

抄録

Base sequences of cytochrome b and D-loop regions in mtDNA were determined to examine the phylogenetic relationship between the Jungle Crow Corvus macrorhynchos and the Carrion Crow C. corone. The extent of homologies of base sequences and amino acids in cytochrome b (690bp) between Jungle and Carrion Crows was 91.6 and 99.1%, respectively. The similarity of the base sequences of the D-loop between Jungle and Carrion Crows was shown to be 98%, which was higher in comparison with those between them and the Rook C. frugilegus (87.4-87.6%, respectively). These findings suggest that the Jungle and Carrion crows are more closely related to each other than to the Rook.
