Molecular Phylogenetic Position of Hexacontium Pachydermum Jørgensen (Radiolaria)

In this study, we sequenced the Received in revised form 3 August 2009 18S rRNA gene of H. pachydermum and of three spherical spumellarians of Cladococcus viminalis Haeckel, Accepted 7 August 2009 Arachnosphaera myriacantha Haeckel, and Astrosphaera hexagonalis Haeckel. Our molecular phylogenetic analysis revealed that the spumellarian species of C. viminalis, A. myriacantha, and A. hexagonalis form a Keywords: monophyletic group. Moreover, this clade occupies a sister position to the clade comprising the spongodiscid Radiolaria fi Entactinarida spumellarians, coccodiscid spumellarians, and H. pachydermum. This nding is contrary to the results of Spumellarida morphological studies based on internal spicular morphology, placing H. pachydermum in the order Nassellarida Entactinarida, which had been considered to have a common ancestor shared with the nassellarians. 18S rRNA gene © 2009 Elsevier B.V.

The amoeba industry has proposed the use of Willaertia magna as a natural biocide to control L. pneumophila proliferation in cooling towers. Here, transcriptomic and proteomic studies were carried out in order to expand knowledge on W. magna produced in a bioreactor. Illumina RNA-seq generated 217 million raw reads. A total of 8790 transcripts were identified, of which 6179 and 5341 were assigned a function through comparisons with National Center of Biotechnology Information (NCBI) reference sequence and the Clusters of Orthologous Groups of proteins (COG) databases, respectively. -

Protist Phylogeny and the High-Level Classification of Protozoa
Europ. J. Protistol. 39, 338–348 (2003) © Urban & Fischer Verlag http://www.urbanfischer.de/journals/ejp Protist phylogeny and the high-level classification of Protozoa Thomas Cavalier-Smith Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK; E-mail: [email protected] Received 1 September 2003; 29 September 2003. Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane). -

Previous work has divided eukaryotic diversity into a small number of high-level ‘supergroups’, many of which receive strong support in phylogenomic analyses. However, the abundance of data in phylogenomic analyses can lead to highly supported but incorrect relationships due to systematic phylogenetic error. Further, the paucity of major eukaryotic lineages (19 or fewer) included in these genomic studies may exaggerate systematic error and reduces power to evaluate hypotheses. -

Based on 2 sampling campaigns on the Greek island of Lesvos in 2009 and 1 in northern Greece in 2012, this study provides first records of 3 intracellular eukaryotic pathogens infecting filamentous brown algae at these locations: Eury - chas ma dicksonii, Anisolpidium sphacellarum, and A. ectocarpii. Field and microscopic observa- tions of the 3 pathogens are complemented by the first E. dicksonii large subunit ribosomal RNA (LSU rRNA) gene sequence analyses of isolates from Lesvos and other parts of the world. -

These organisms are widely occurring in marine and freshwater habitats, mostly infecting filamentous green early-diverging algae. Presently, all species are only known from their morphology and descriptive life cycle traits. None of the seven new taxa species classified in Sirolpidium, including the type species, S. bryopsidis, has been rediscovered and studied for their Oomycota molecular phylogeny, so far. Originally, the genus was established to accommodate all parasites of filamentous marine Petersenia green algae. In the past few decades, however, Sirolpidium has undergone multiple taxonomic revisions and several species phylogeny parasitic in other host groups were added to the genus. While the phylogeny of the marine rhodophyte- and phaeophyte- Pontismataceae infecting genera Pontisma and Eurychasma, respectively, has only been resolved recently, the taxonomic placement Sirolpidiaceae of the chlorophyte-infecting genus Sirolpidium remained unresolved.
