✦ Synopsis
We have sequenced the nuclear and mitochondrial small subunit rRNA genes (ms) and the mitochondrial genes coding for subunits 1 and 3 of the cytochrome oxidase (coxl and cox3, respectively) of the chytridiomycete Allomyces macrogynus. Phylogenetic trees inferred from the derived COX1 and COX3 proteins and the nuclear ms sequences show with good bootstrap support that A. macrogynus is an early diverging fungus. The trees inferred from mitochondrial rns sequences do not yield a topology that is supported by bootstrap analysis. The similarity and the relative robustness of the nuclear rns and the mitochondrial proteinderived phylogenetic trees suggest that protein sequences are of higher value than rRNA sequences for reconstructing mitochondrial evolution. In addition, our trees support a monophyletic origin of mitochondria for the range of analyzed eukaryotes.
