In a study of the nuclear behavior of Paramecium aurelia, a process of self‐fertilization, autogamy, has been discovered and traced through its essential steps. Autogamy is the counterpart, in a…

Timing and characteristics of nuclear events during conjugation and genomic exclusion in Paramecium multimicronucleatum
- Xue ZhangXiaoteng Lu F. Gao
- Biology
- 2022
This study investigates the conjugation process in Paramecium multimicronucleatum and describes for the first time the process of genomic exclusion occurring between amicron nucleate and micronucleate cells of P. multimicRONucleatum, resulting in both exconjugants being homozygotes.
CYTOLOGY OF CONJUGATION IN PARAMECIUM MULTIMICRONUCLEATUM, SYNGEN 2, STOCK II.
- A. Barnett
- Biology
- 1964
Following cross-fertilization, the two exconjugant clones should be identical in phenotype for traits under direct genic control, but any trait, however, under the control of differently determined macronuclei should follow the segregation of the macronuclear anlagen at the second cell division.
Direct Observation of the Transfer of Pronuclei in Living Conjugants of Paramecium bursaria.
- R. Wichterman
- Biology
- 1946
At the present time three sexual processes have been described for Paramecium in which three micronuclear (pregamic) divisions lead to synkaryon formation, and a new sexual process called cytogaqy is discovered.
Autogamy in Paramecium polycaryum
- W. Diller
- Biology
- 1954
Mass cultures of a stock of Paramecium polycaryum maintained over a period of several years showed abundant and frequent nuclear reorganization stages resembling those of ex-conjugant and…
Reorganisation du Type Endomixique chez les Loxodidae et chez les Centrophorella
- E. Fauré-Frémiet

- 1954
New investigations of the nuclear cycle in the gymnostome ciliate Loxodes rostrum verify the long-neglected hypothesis proposed by Butschli that in this multinucleated ciliate the macronuclei never…
Protoplasmic Streaming and Nuclear Differentiation during Conjugation of Paramecium caudatum
- Kumiko KobayashiC. YoshimuraK. Mikami
- Biology
- 1999
The velocity of protoplasmic streaming during conjugation does not directly correlated with the micronuclear behavior, and the cessation seems to be very convenient for intracellular positioning of the cytoplasmic determinants and/or of themicronuclei for the nuclear differentiation.
Autogamy in Frontonia leucas (Ehrbg.)
- R. Devi
- Biology
- 1961
Autogamy in Frontonia leucas is described for the first time and there is some indirect evidence of a relationship between the dissolution of the old macronucleus and the development of the new.
An abbreviated conjugation process in Paramecium trichium.
- W. Diller
- Biology
- 1949
1. A process of "abbreviated" conjugation occurs in one race of P. trichium in which the number of micronuclear divisions is reduced to three (or possibly four) from the "standard" pattern of five or…

On the method of macronuclear disintegration during endomixis in Paramecium aurelia
- L. L. WoodruffH. Spencer
- Biology
- 1922
It is clear that although all the data thus far at hand indicate that chromatin-body formation is the typical method of destroying the macronucleus in endomixis, nevertheless under certain unknown conditions the formation of Chromatin-ribbons, until now regarded as diagnostic of conjugation, occurs in endmixis.

Experiments to determine the possibility of inducing an independent reorganization process in conjugating individuals by preventing nuclear interchange indicated that endomixis had not occurred in this race during encystment, and additional evidence further supported this view.
