Enzyme variation between syngens in Paramecium aurelia

Biochemical Genetics, 1970
Five enzymes (succinic dehydrogenase isocitrate dehydrogenase, glutamate dehydrogenase, β-hydroxybutyrate dehydrogenase, and fumarase) in the ciliate Paramecium aurelia have been examined by starch gel electrophoresis. Relatively few variants were found among stocks belonging to a given syngen and only in two out of the five enzymes studied. Comparison

Genetic Dissection of Active Electrogenesis in Paramecium aurelia

Nature, 1974
NEUROPHYSIOLOGISTS frequently use various drugs and toxins to interfere with specific membrane mechanisms. A genetic approach can achieve the same results. In taking this approach to the problem of excitation it is desirable to have an organism, like Paramecium, on which both formal genetic1 and orthodox electrophysiological2 studies can be made.

Behavioral Mutants of Paramecium Aurelia

1973
A Paramecium can be viewed as a eucaryotic organism capable of behavior, but it can also be regarded as a unicell comparable to excitable cells, such as hair cells, neurons, etc. in multicellular forms. The genetics of behavior in Paramecium aurelia makes use of both its organismic and cellular properties.

[Catalase activity in Paramecium aurelia].

Comptes rendus des seances de la Societe de biologie et de ses filiales, 1976
The catalase activity of Paramecium aurelia was determined by the procedure of Sinha after bacteria elimination from culture medium. A significant level of catalase activity was shown, higher than in other cell kinds. The role of catalase activity in Paramecium sensitivity to low doses of ionizing radiations is discuted.

Calcium channels in Paramecium aurelia.

Progress in clinical and biological research, 1978
Reversal of swimming direction in paramecium is dependent on the calcium influx through the excitable-membrane calcium channels. Several mutants of Paramecium aurelia have been selected on the basis of their resistance to the paralyzing effect of barium.

INDUCTION OF ENDOMIXIS IN PARAMECIUM AURELIA

The Biological Bulletin, 1937
In both stocks R and W of P. aurelia, endomixis can be induced by placing at 31° C. small mass cultures containing the surplus animals from isolation lines. In stock R, induction cultures set up soon after endomixis yielded conjugants, so that the induction of endomixis could not be studied quantitatively in these.
