The Endosymbionts of Paramecium
CRC Critical Reviews in Microbiology, 1974AbstractProtozoan cells harbor many different types of endosymbionts. They can be viruses, bacteria, algae, fungi, or even defy classification in relation to free-living organisms. A general description of the types is available in Kirby1 and some are shown in Table 1.

Mitochondrial Genetics in Paramecium
Nature, 1972RESISTANCE to erythromycin and chloramphenicol in yeast has been shown to be controlled by non-Mendelian genetic factors in mitochondrial DNA1,2. Because paramecium has particular advantages for the study of cytoplasmic genetics3, we have made some genetic and biochemical studies on drug-resistant variants of this ciliate, working with syngens 1 and 4 ...

Chemoreception in Paramecium [PDF]
, 1994 Aquatic organisms have the capability of detecting and responding to chemical stimuli. The stimulus can signify the presence of food, mates, predators, or a place to settle and continue development. Unicellular aquatic organisms are not exceptions and as an example, I discuss chemoresponses of Paramecium tetraurelia, a ciliated eukaryotic microorganism.

The Cell Surface of Paramecium
1959Publisher Summary This chapter provides a general description of the structure of the cell surface of Paramecium . The trichocysts, at their tips, are homologous with cilia. If the ciliary corpuscles composing the cell surface are like a layer of packed peas, then the trichocysts underlying the surface in orderly array are somewhat like a second ...

A theory of gravikinesis in Paramecium
Advances in Space Research, 1996The archaic eukaryote unicellular microorganism, Paramecium, is propelled by thousands of cilia, which are regulated by modulation of the membrane potential. Ciliates can successfully cope with gravity, which is the phylogenetically oldest stimulus for living things.

Imagine that in 1678 you are Christiaan Huygens or Antonie van Leeuwenhoek seeing paramecia swim gracefully across the field of view of your new microscope. These unicellular, free-living, and swimming cells might have remained a curiosity if not for the ability of H.S. Jennings (Behavior of the lower organisms.

Gene overexpression in P. tetraurelia Gene overexpression can be achieved by introducing more copies of the target gene into the MAC in P. tetraurelia (Table 1). A small portion of exogenous DNA introduced into the MAC of P. tetraurelia can be integrated into the chromosomes, similar to Tetrahymena, while most is added with Paramecium telomerelike ...

The study of antigens in paramecia has yielded valuable genetic information and criteria for showing resemblances and differences in clones, strains, and species of Paramecium and other protozoa. In a number of cases, serological methods have proved to be more precise than certain other methods in demonstrating relationships among organisms.

In a model analysis the excitation mechanism of Paramecium is simulated. The model is based on a specific Ca channel mechanism located in the ciliary part of the membrane. The Ca2+ permeability depends on transmembrane voltage and the binding of cations to channel subunits.
