pubmed:abstractText |
Phylogenies based on mitochondrial DNA (mtDNA) may represent gene trees that may not be congruent with the equivalent species tree. One solution to this problem is to include additional, independent loci from the nuclear genome. Sequence data from the seventh intron of the beta-fibrinogen gene were generated for 25 specimens of vipers, including 8 nominal species of the Trimeresurus complex of Asian pit vipers. Phylogenetic trees were generated using maximum-parsimony and maximum-likelihood methods. The taxonomic level at which the intron provided significant phylogenetic information was examined and the trees were compared to those produced from previously obtained mtDNA cytochrome b sequences. A variety of different approaches (separate analyses, conditional data combination, and consensus) were used in an attempt to provide a sound organismal phylogeny based on both nuclear and mtDNA data sets. We discuss the implications for the gene tree-species tree debate and its particular relevance to medically important organisms.
