Draft Genome Sequence of Holospora undulata Strain HU1, a Micronucleus-Specific Symbiont of the Ciliate Paramecium caudatum
Holospora undulata is a micronucleus-specific symbiont of the ciliate Paramecium caudatum. We report here the draft genome sequence of H. undulata strain HU1. This genome information will contribute to the study of symbiosis between H. undulata and the host P. caudatum.
متن کاملInfection of macronuclear anlagen of Paramecium caudatum with the macronucleus-specific symbiont Holospora obtusa.
The gram-negative bacterium Holospora obtusa is an endonuclear symbiont of Paramecium caudatum, which is incorporated into the host cells via the food vacuoles and infects their macronucleus exclusively, but never the micronucleus. Since these two kinds of nuclei originate from a fertilization nucleus, it is assumed that the macronucleus acquires a property necessary for it to be recognized by ...
متن کامل“Candidatus Gortzia shahrazadis”, a Novel Endosymbiont of Paramecium multimicronucleatum and a Revision of the Biogeographical Distribution of Holospora-Like Bacteria
Holospora spp. and "Candidatus Gortzia infectiva", known as Holospora-like bacteria (HLB), are commonly found as nuclear endosymbionts of ciliates, especially the Paramecium genus. HLB are related by phylogenetic relationships, morphological features, and life-cycles, which involve two alternating morphotypes: reproductive and infectious forms (RF, IF). In this paper we describe a novel species...
متن کاملInfection and maintenance of Holospora obtusa, a macronucleus-specific bacterium of the ciliate Paramecium caudatum.
The gram-negative bacterium Holospora obtusa is a macronucleus-specific symbiont of the ciliate Paramecium caudatum, which invades the host cell via a food vacuole, infects its macronucleus and grows exclusively in the nucleus. From infection experiments, we showed that a property of the macronucleus that is necessary for it to be recognized and infected by H. obtusa is commonly provided by P. ...
متن کاملIsolation and Characterization of Macronuclei of Paramecium Caudatum Infected with the Macronucleus-specific Bacterum Holospora Obtusa
Endosymbiotic associations between bacteria and eukaryotes are commonly reported (Taylor, 1983). The prokaryotic cell (the cytobiont (Taylor, 1979) or endocytobiont (Schwemmler, 1979)) may live non-specifically within the intracellular habitat provided by the host, but some endosymbiotic bacteria are specialized to invade specific cellular organelles. Three species of the bacterial genus Holosp...
