|PubMed Abstract||Phylogenetic utility of the mitochondrial COI (cytochrome oxidase subunit I) and nuclear Gpdh (glycerol-3-phosphate dehydrogenase) genes was studied in the Drosophila melanogaster species group. The rate of substitution was higher in the COI gene than in the Gpdh gene. In addition, multiple substitutions, not only for transitional but also for transversional substitutions, occurred faster in the COI gene. None of the trees obtained using the COI gene supported the well-established monophyly of the ananassae subgroup. In addition, the incongruence length difference test, Templeton test, and partitioned Bremer support revealed that the trees based on the COI data are considerably different from those based on the Gpdh and the combined data set. Thus, the COI gene did not show good phylogenetic performance in the melanogaster group. The present analyses based on the Gpdh gene and the combined data set revealed that the ananassae subgroup branched off first in the melanogaster group followed by the montium subgroup and further by the melanogaster subgroup in contrast to the most recent phylogenetic hypothesis based on Amy multigenes.|
