A well supported multi gene phylogeny of 52 dictyostelia.

ABSTRACT: The Dictyostelid social amoebas are a popular model system for cell- and developmental biology and for evolution of sociality. Small subunit (SSU) ribosomal DNA-based phylogenies subdivide the known 150 species into four major and some minor groups, but lack resolution within groups, particularly group 4, and, as shown by genome-based phylogenies of 11 species, showed errors in the position of the root and nodes separating major clades. We are interested in the evolution of cell-type specialization, which particularly expanded in group 4. To construct a more robust phylogeny, we first included 7 recently sequenced genomes in the genome-based phylogeny of 47 functionally divergent proteins and next selected 6 proteins (Agl, AmdA, PurD, PurL, RpaA, SmdA) that independently or in sets of two
