The mitochondrial genome of P. mycophagum was deposited under the Accession number KY75056 and that of P. aurantium under the Accession number KY75057. The RNAseq reads can be found in Bioproject Accession PRJNA338377. All sequence and annotation data are also available directly from the authors. The P. aurantium strain is deposited in the Jena Microbial Resource Collection (JMRC) under accession number SF0012540. Abstract Establishment of multicellularity represents a major transition in eukaryote evolution. A subgroup of Amoebozoa, the dictyos- teliids, has evolved a relatively simple aggregative multicellular stage resulting in a fruiting body supported by a stalk. Protosteloid amoeba, which are scattered throughout the amoebozoan tree, differ by producing only one or few single stalked spores. -

A Flagellate-To-Amoeboid Switch in the Closest Living Relatives of Animals
RESEARCH ARTICLE A flagellate-to-amoeboid switch in the closest living relatives of animals Thibaut Brunet1,2*, Marvin Albert3, William Roman4, Maxwell C Coyle1,2, Danielle C Spitzer2, Nicole King1,2* 1Howard Hughes Medical Institute, Chevy Chase, United States; 2Department of Molecular and Cell Biology, University of California, Berkeley, Berkeley, United States; 3Department of Molecular Life Sciences, University of Zu¨ rich, Zurich, Switzerland; 4Department of Experimental and Health Sciences, Pompeu Fabra University (UPF), CIBERNED, Barcelona, Spain Abstract Amoeboid cell types are fundamental to animal biology and broadly distributed across animal diversity, but their evolutionary origin is unclear. The closest living relatives of animals, the choanoflagellates, display a polarized cell architecture (with an apical flagellum encircled by microvilli) that resembles that of epithelial cells and suggests homology, but this architecture differs strikingly from the deformable phenotype of animal amoeboid cells, which instead evoke more distantly related eukaryotes, such as diverse amoebae. Here, we show that choanoflagellates subjected to confinement become amoeboid by retracting their flagella and activating myosin- based motility. This switch allows escape from confinement and is conserved across choanoflagellate diversity. The conservation of the amoeboid cell phenotype across animals and choanoflagellates, together with the conserved role of myosin, is consistent with homology of amoeboid motility in both lineages. We hypothesize that -
Catalogue of Protozoan Parasites Recorded in Australia Peter J. O
1 CATALOGUE OF PROTOZOAN PARASITES RECORDED IN AUSTRALIA PETER J. O’DONOGHUE & ROBERT D. ADLARD O’Donoghue, P.J. & Adlard, R.D. 2000 02 29: Catalogue of protozoan parasites recorded in Australia. Memoirs of the Queensland Museum 45(1):1-164. Brisbane. ISSN 0079-8835. Published reports of protozoan species from Australian animals have been compiled into a host- parasite checklist, a parasite-host checklist and a cross-referenced bibliography. Protozoa listed include parasites, commensals and symbionts but free-living species have been excluded. Over 590 protozoan species are listed including amoebae, flagellates, ciliates and ‘sporozoa’ (the latter comprising apicomplexans, microsporans, myxozoans, haplosporidians and paramyxeans). Organisms are recorded in association with some 520 hosts including mammals, marsupials, birds, reptiles, amphibians, fish and invertebrates. Information has been abstracted from over 1,270 scientific publications predating 1999 and all records include taxonomic authorities, synonyms, common names, sites of infection within hosts and geographic locations.

Supporting Material
Supporting Text Recursions. We developed a model to investigate the evolution of ploidy levels in the presence of host-parasite interactions between a focal and nonfocal species. The focal species is assumed to have two loci, a ploidy modifier locus with alleles C1 and C2 and an interaction locus with alleles A and a. Thus there are four haploid gamete types in the focal species: AC1 with frequency X1, aC1 with frequency X2, AC2 with frequency X3, and aC2 with frequency X4. The modifier locus influences ploidy levels by altering the timing of meiosis; diploid zygotes of genotype CiCj have a probability, dij, of undergoing meiosis late in life, thus experiencing host-parasite selection as a diploid, versus early in life, thus experiencing selection as a haploid (Fig. 2). The nonfocal species is assumed to be a sexual diploid, having only a brief haploid stage, although results derived with a haploid nonfocal species were similar. For clarity, we assume that the A locus in the focal species interacts with a B locus in the nonfocal species, with alleles B and b. Note that Table 1 differs from this convention by referring to alleles in both species as A and a. We use a different notation here to avoid additional subscripts in the equations. The frequencies of alleles are denoted by pA, pa, pC1, and pC2 in the focal species and pB and pb in the nonfocal species, all measured at the gamete stage of the life cycle (Fig. 2). Also measured at this stage is D = (X1 X4 - X2 X3), the disequilibrium between the modifier and selected loci in the focal species. -

The genus Hyperamoeba Alexeieff, 1923 was established to accommodate an aerobic amoeba exhibiting three life stages— amoeba, flagellate, and cyst. As more species/strains were isolated, it became increasingly evident from small subunit (SSU) gene phylo- genies and ultrastructure that Hyperamoeba is polyphyletic and its species occupy different positions within the class Myxogastria. To pinpoint Hyperamoeba strains within other myxogastrid genera we aligned numerous myxogastrid sequences: whole small subunit ribo- somal (SSU or 18S rRNA) gene for 50 dark-spored (i.e. Stemonitida and Physarida) Myxogastria (including a new ‘‘Hyperamoeba’’/ Didymium sequence) and a 400-bp SSU fragment for 147 isolates assigned to 10 genera of the order Physarida. Phylogenetic analyses show unambiguously that the type species Hyperamoeba flagellata is a Physarum (Physarum flagellatum comb. nov.) as it nests among other Physarum species as robust sister to Physarum didermoides. Our trees also allow the following allocations: five Hyperamoeba strains to the genus Stemonitis; Hyperamoeba dachnaya, Pseudodidymium cryptomastigophorum, and three other Hyperamoeba strains to the genus Didymium; and two further Hyperamoeba strains to the family Physaridae. -
