Eumycetozoa = Amoebozoa?: SSUrDNA Phylogeny of Protosteloid Slime Molds and Its Significance for the Amoebozoan Supergroup

摘要: Amoebae that make fruiting bodies consisting of a stalk and spores classified as closely related to the myxogastrids have classically been placed in taxon Eumycetozoa. Traditionally, there are three groups comprising Eumycetozoa: myxogastrids, dictyostelids, so-called protostelids. Dictyostelids both multicellular may contain hundreds spores. Protostelids those amoebae simple one or few Protostelid-like organisms suggested progenitors they used formulate hypotheses on evolution within group. Molecular phylogenies published for but little molecular phylogenetic work has done Here we provide trees based small subunit ribosomal RNA gene (SSU) include 21 protostelids along with publicly available sequences from wide variety other eukaryotes. SSU recover seven well supported clades do not appear be specifically another often interspersed among established never reported fruit. In fact, show at least two taxa unambiguously belong amoebozoan lineages where reported. These analyses indicate can reject monophyletic Eumycetozoa, s.l. For this reason, will hereafter refer slime molds protosteloid and/or molds, results add our understanding biodiversity, demonstrate paradigms nonfruiting sporulating must integrated. Finally, suggest strategies future research amoebae, discuss impact taxonomists phylogenomicists.
