Electron microscopic identification of RNA- and DNA- containing structures in the preparations of isolated macronuclei of ciliates Bursaria truncatella
RNAand DNA-containing structures in the ciliate Bursaria truncatella were studied on ultrathin sections and spread preparations of individual macronuclei isolated at middle interphase. To label DNA-containing structures we used antiDNA antibodies and protein A-colloidal gold complexes. To label RNP structures, complexes of gold with RNase A were used. Chromatin structures in the form of accumul...
متن کاملExcystment-Dependent Alteration of Protein Expression in Terrestrial Ciliate Colpoda cucullus
Protein expression during the excystment of Colpoda cucullus was studied by SDS-PAGE. The expression levels of 60-, 50- and 49-kDa proteins were markedly changed from the early to later stage of excystment. The 60-kDa protein (p60) was temporarily expressed first, and its expression was inhibited by actinomycin D. LC-MS/MS analysis showed that the amino acid sequences of p60 partially coincided...
متن کاملPhotoadaptation Alters the Ingestion Rate of Paramecium bursaria, a Mixotrophic Ciliate.
Bacteriovorous protozoa harboring symbiotic algae are abundant in aquatic ecosystems, yet despite a recent interest in protozoan bacterivory, the influence of light on their ingestion rates has not been investigated. In this study, Paramecium bursaria containing endosymbiotic Chlorella was tested for the effect of light on its ingestion rate. P. bursaria was grown for 4 to 6 days under five dif...
متن کاملAn experimental test of the symbiosis specificity between the ciliate Paramecium bursaria and strains of the unicellular green alga Chlorella.
The ciliate Paramecium bursaria living in mutualistic relationship with the unicellular green alga Chlorella is known to be easily infected by various potential symbionts/parasites such as bacteria, yeasts and other algae. Permanent symbiosis, however, seems to be restricted to Chlorella taxa. To test the specificity of this association, we designed infection experiments with two aposymbiotic P...
متن کاملThe Kinetics of Excystment in Colpoda Duodenaria
1. Extensive experimental data have been collected on the time required for the excystment process of the small ciliate Colpoda duodenaria throughout a range of temperatures of 8 degrees through 32 degrees C. and a range of concentrations of yeast extract excystment media of 0.08 through 22.4 gm./liter. 2. The excystment process has been separated into two periods, the first inversely proportio...
