Movement of extrusomes in the heliozoon Actinophrys sol was characterized at surfaces of the cell body and giant food vacuoles where microtubules are absent. Extrusomes moved in a saltatory manner at an average velocity of 0.5 µms-1. The highest velocity observed was 2.1 µms-1. Cytochalasin B (50 µg/ml) strongly inhibited extrusome movement at the surfaces of newly-formed food vacuoles, suggesting that the actomyosin system is involved in the organelle transport in Actinophrys.

It has been found at sites around the world. The organism has an irregular star-shaped body from which radiate thin pseudopodia with extrusomes. There are 2 inactive flagella. The organism is normally sedentary but, under adverse conditions, the arms are resorbed, the flagella become active, and the organism becomes a motile non-feeding flagellate. The ecological niche occupied by this organism and its phylogenetic affinities are discussed.

  • ABSTRACT Title of Dissertation: IDENTIFICATION, LIFE HISTORY
    ABSTRACT Title of Dissertation: IDENTIFICATION, LIFE HISTORY, AND ECOLOGY OF PERITRICH CILIATES AS EPIBIONTS ON CALANOID COPEPODS IN THE CHESAPEAKE BAY Laura Roberta Pinto Utz, Doctor of Philosophy, 2003 Dissertation Directed by: Professor Eugene B. Small Department of Biology Adjunct Professor D. Wayne Coats Department of Biology and Smithsonian Environmental Research Center Epibiotic relationships are a widespread phenomenon in marine, estuarine and freshwater environments, and include diverse epibiont organisms such as bacteria, protists, rotifers, and barnacles. Despite its wide occurrence, epibiosis is still poorly known regarding its consequences, advantages, and disadvantages for host and epibiont. Most studies performed about epibiotic communities have focused on the epibionts’ effects on host fitness, with few studies emphasizing on the epibiont itself. The present work investigates species composition, spatial and temporal fluctuations, and aspects of the life cycle and attachment preferences of Peritrich epibionts on calanoid copepods in Chesapeake Bay, USA. Two species of Peritrich ciliates (Zoothamnium intermedium Precht, 1935, and Epistylis sp.) were identified to live as epibionts on the two most abundant copepod species (Acartia tonsa and Eurytemora affinis) during spring and summer months in Chesapeake Bay. Infestation prevalence was not significantly correlated with environmental variables or phytoplankton abundance, but displayed a trend following host abundance. Investigation of the life cycle of Z. intermedium suggested that it is an obligate epibiont, being unable to attach to non-living substrates in the laboratory or in the field. Formation of free-swimming stages (telotrochs) occurs as a result of binary fission, as observed for other peritrichs, and is also triggered by death or molt of the crustacean host.

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).

As concerns Trypanosoma cruzi that causes Chagas disease, the insect vector-derived metacyclic trypomastigotes (MT) initiate infection by invading host cells, and later blood trypomastigotes disseminate to diverse organs and tissues. Studies with MT generated in vitro and tissue culture-derived trypomastigotes (TCT), as counterparts of insect- borne and bloodstream parasites, have implicated members of the gp85/trans-sialidase superfamily, MT gp82 and TCT Tc85-11, in cell invasion and interaction with host factors. Here we analyzed the gp82 structure/function characteristics and compared them with those previously reported for Tc85-11. One of the gp82 sequences identified as a cell binding site consisted of an alpha-helix, which connects the N-terminal beta-propeller domain to the C- terminal beta-sandwich domain where the second binding site is nested. In the gp82 structure model, both sites were exposed at the surface. Unlike gp82, the Tc85-11 cell adhesion sites are located in the N-terminal beta-propeller region. The gp82 sequence corresponding to the epitope for a monoclonal antibody that inhibits MT entry into target cells was exposed on the surface, upstream and contiguous to the alpha-helix. Located downstream and close to the alpha-helix was the gp82 gastric mucin binding site, which plays a central role in oral T.

We aimed at directly demonstrating the sulfur-oxidizing, chemoautotrophic nature of the symbionts and at investigating putative carbon transfer from the symbiont to the ciliate host.

We show that symbiont cells x substantial amounts of inorganic carbon in the presence of sulfide, but also (to a lesser degree) in the absence of sulfide by utilizing internally stored sulfur. Isotope labeling patterns point to translocation of organic carbon to the host through both release of these compounds and digestion of symbiont cells. The latter mechanism is also supported by ultracytochemical detection of acid phosphatase in lysosomes and in food vacuoles of ciliate cells.

There are multiple available classification 12 systems that all suffer from differences in naming, incompleteness, presence of multiple non- 13 monophyletic entities and poor correspondence of divergence times. These issues render 14 taxonomic comparisons across the main groups of eukaryotes and all life in general difficult 15 at best. By using the monophyly criterion, roughly comparable time of divergence and 16 information from multiple phylogenetic reconstructions, I propose an alternative 17 classification system for the domain Eukarya to improve hierarchical taxonomical 18 comparability for animals, plants, fungi and multiple protist groups. Following this rationale, 19 I propose 32 kingdoms of eukaryotes that are treated in 10 subdomains. These kingdoms are 20 further separated into 43, 115, 140 and 353 taxa at the level of subkingdom, phylum, 21 subphylum and class, respectively (http://dx.doi.org/10.15156/BIO/587483).

  • Exceptional Species Richness of Ciliated Protozoa in Pristine Intertidal Rock Pools
    MARINE ECOLOGY PROGRESS SERIES Vol. 335: 133–141, 2007 Published April 16 Mar Ecol Prog Ser Exceptional species richness of ciliated Protozoa in pristine intertidal rock pools Genoveva F. Esteban*, Bland J. Finlay School of Biological & Chemical Sciences, Queen Mary, University of London, London E1 4NS, UK ABSTRACT: Marine intertidal rock pools can be found almost worldwide but little is known about the microscopic life forms they support, or the significance of regular tidal inundation. With regard to ciliated Protozoa in rock pools, little progress has been achieved since 1948, when the question was first posed as to how a community of ciliates can remain relatively constant in a rock pool that is flushed twice a day. Here we show that local ciliate species richness is very high and that it may per- sist over time. This elevated species richness can be attributed to ciliate immigration with the in- coming tide, and also to the resident ciliate community that withstands tidal flushing. A 15 cm deep intertidal rock-pool no bigger than 1 m2 on the island of St. Agnes (Scilly Islands, UK) contained at least 85 ciliate species, while a 20 cm-deep rock pool with roughly the same area on Bryher (also in the Scilly Islands) yielded 75 species. More than 20% of the global number of described marine inter- stitial ciliate species was recorded from these rock pools. We explore the paradox of a persisting com- munity assembly living in an ecosystem that is physically highly dynamic.

Abstract Animal and plant communities in tropical rainforests are known to have high alpha diversity within forests, but low beta diversity between forests. By contrast, it is unknown if the microbial protists inhabiting the same ecosystems exhibit similar biogeographic patterns. To evaluate the biogeographies of soil protists in three lowland Neotropical rainforests using metabarcoding data, we estimated taxa-area and distance-decay relationships for three large protist taxa and their subtaxa, at both the OTU and phylogenetic levels, with presence-absence and abundance based measures, and compared the estimates to null models.
