  1. Fenske C, Gunther B. "Electro-fishing" in the lab: a new method to detect acute effects of heavy metals and organic pollutants in invertebrate indicator organisms. Int J Hyg Environ Health. 2001;204:157-63 pubmed
    ..The organic pollutants, in contrast, did not cause detectable changes in ciliates and only led to slight reductions in the migration activity of nematodes, without concentration-dependent gradations. ..
  2. Hemmersbach R, Krause M, Braucker R, Ivanova K. Graviperception in ciliates: steps in the transduction chain. Adv Space Res. 2005;35:296-9 pubmed
    ..The corresponding data confirm the relaxation of the graviresponses in microgravity as well as the existence of thresholds of graviresponses, which are found to be in the range of 0.4xg (gravikinesis) and 0.6xg (gravitaxis). ..
  3. Görtz H. Intracellular bacteria in ciliates. Int Microbiol. 2001;4:143-50 pubmed
    ..Symbionts that express a killer toxin affecting non-infected ciliates achieve high infection rates in a host population. whereas certain infectious bacteria may only show a low prevalence. ..
  4. Kusch J, Czubatinski L, Wegmann S, Hubner M, Alter M, Albrecht P. Competitive advantages of Caedibacter-infected Paramecia. Protist. 2002;153:47-58 pubmed
    ..Caedibacter-infected predators may influence competition between Paramecium strains by release of toxic parasites into the environment that are harmful to uninfected strains. ..
  5. Hofmann F. The biology of cyclic GMP-dependent protein kinases. J Biol Chem. 2005;280:1-4 pubmed
  6. Catania F, McGrath C, Doak T, Lynch M. Spliced DNA sequences in the Paramecium germline: their properties and evolutionary potential. Genome Biol Evol. 2013;5:1200-11 pubmed publisher
    ..Our findings indicate interconversion between somatic--often coding--DNA sequences and noncoding IESs, and provide insights into the role of DNA splicing in creating potentially functional genetic innovation. ..
  7. Schrallhammer M, Fokin S, Schleifer K, Petroni G. Molecular characterization of the obligate endosymbiont "Caedibacter macronucleorum"Fokin and Görtz, 1993 and of its host Paramecium duboscqui strain Ku4-8. J Eukaryot Microbiol. 2006;53:499-506 pubmed
    ..Nevertheless, "C. macronucleorum" and C. caryophilus can be easily discriminated on the basis of a highly variable stretch of nucleotides that interrupts the 16S rRNA genes of both organisms. ..
  8. Klöppel C, Muller A, Marker S, Simon M. Two isoforms of eukaryotic phospholipase C in Paramecium affecting transport and release of GPI-anchored proteins in vivo. Eur J Cell Biol. 2009;88:577-92 pubmed publisher
    ..This is the first molecular data on endogenous Paramecium PLCs with the described properties affecting GPI anchors in vitro and in vivo. ..
  9. Plattner H, Braun C, Klauke N, Lange S. Veratridine triggers exocytosis in Paramecium cells by activating somatic Ca channels. J Membr Biol. 1994;142:229-40 pubmed
    ..e., nonciliary cell membrane and that a Ca2+ influx triggers exocytotic membrane fusion. The type of Ca channels involved remains to be established...

    ..Furthermore, our data suggest that GTP gamma S interferes with synthesis of dolichol monophosphate, indicating that the dolichol kinase is regulated by the heterotrimeric G proteins. ..
