Chemical defense by means of pigmented extrusomes in the ciliate Blepharisma japonicum
Summary The defensive function of pigment granules in Blepharisma japonicum against the predatory ciliate Dileptus margaritifer was further investigated by 1) observing the discharge of pigmentExpand
Defensive function of trichocysts in Paramecium
A putative defensive function of trichocysts in Paramecium has been tested experimentally. Cells of trichocyst-non-discharge (tnd) mutant, artificially induced trichocyst-deficient cells, and intactExpand

Mutant strain d48 of Paramecium tetraurelia lacks the gene for antigen A in the macronucleus, whereas this gene is present in the micronucleus. Transfer of macronucleoplasm from the wild type toExpand
The Role of Trichocyst Discharge and Backward Swimming in Escaping Behavior of Paramecium from Dileptus margaritifer 1
Trichocyst discharge is an effective defense of Paramecium against Dileptus margaritifer. The possible defensive function of backward swimming, which often follows trichocyst discharge uponExpand
Newly sequenced eRF1s from ciliates: the diversity of stop codon usage and the molecular surfaces that are important for stop codon interactions.
The genetic code of nuclear genes in some ciliates was found to differ from that of other organisms in the assignment of UGA, UAG, and UAA codons, which are normally assigned as stop codons. In someExpand
Defence function of pigment granules in Stentor coeruleus
Pigment granules in Stentor coeruleus are extrusive organelles containing the pigment, stentorin, which provides the blue-green colouration to this ciliate. We studied the defence function of theseExpand
Defensive function of pigment granules in Blepharisma japonicum.
The defensive function of pigment granules in the red heterotrichous ciliate Blepharisma japonicum was studied by comparing normally-pigmented red cells, albino mutant cells and light-bleached cellsExpand
Toxic and Phototoxic Properties of the Protozoan Pigments Blepharismin and Oxyblepharismin *
Abstract— The toxic and phototoxic properties of blepharismin and oxyblepharismin that were purified from the pigments of a ciliated protozoan, Blepharisma japonicum, by thin‐layer chromatography,Expand
Evidence for a Viral Macronuclear Endosymbiont in Paramecium caudatum
ABSTRACT. Some strains of P. caudatum contain macronuclear inclusion bodies that are morphologically distinct from bacteria. They vary in number as well as in size in each macronucleus. The inclusionExpand
Defense Function of Pigment Granules in the Ciliate Blepharisma japonicum against Two Predatory Protists,Amoeba proteus (Rhizopodea) and Climacostomum virens (Ciliata)
Abstract The defense function of pigment granules in the red ciliate Blepharisma japonicum against two predatory protists, Amoeba proteus and Climacostomum virens, was investigated by (1) comparingExpand
