Consensus phylogeny of Dictyostelium

Experientia. 1995 Dec 18;51(12):1110-5. doi: 10.1007/BF01944728.


The evolutionary relationship of Dictyostelium discoideum to the yeasts, fungi, plants, and animals is considered on the basis of physiological, morphological and molecular characteristics. Previous analyses of five proteins indicated that Dictyostelium diverged after the yeasts but before the metazoan radiation. However, analyses of the small ribosomal subunit RNA indicated divergence prior to the yeasts. We have extended the molecular phylogenetic analyses to six more proteins and find consistent evidence for a more recent common ancestor with metazoans than yeast. A consensus phylogeny generated from these new results by both distance matrix and parsimony analyses establishes Dictyostelum's place in evolution between the yeasts Saccharomyces cerevisiae and Schizzosaccharomyces pombe and the worm Caenorhabditis elegans.
