An Angiosperm Phylogeny Inferred from Nucleotide Sequences of Four Mitochondrial Genes.
An angiosperm phylogeny is inferred from nucleotide sequences of four mitochondrial genes, atp1, matR, nad5 and rps3, using a maximum likelihood method as implemented in RAXML. The results are largely congruent with those obtained from previous analyses of chloroplast and nuclear genes. These results demonstrate that 1) mitochondrial genes are informative markers for angiosperm phylogeny reconstruction, 2) the previously reconstructed angiosperm phylogeny based on markers from chloroplast and nuclear genomes are supported by evidence from the mitochondrial genome, 3) some critical details such as the composition of the first diverging lineage of angiosperm phylogeny and placement of Ceratophyllum are different in the mitochondrial gene trees, and 4) horizontal transfer of mitochondrial genes reported in earlier studies is not rampant despite its occasional occurrence.
