Interpretation Cytophotometrique Des Phenomenes Micronucleaires Au Cours De La Division Binaire Et Des Divisions Pregamiques Chez Paramecium Trichium

Le phenomene general de la biosynthese de I'ADN au cours de la division cellulaire et au cours de la meiose a fait l'objet de nombreux travaux. Au moyen de techniques diverses, cytophotom6triques et radioautographiques, un grand nombre de rsultats a te obtenu concernant la teneur en ADN des noyaux cellulaires des tissus des metazoaires. En ce qui concerne les protozoaires et en particulier les ...

A suppressor gene involved in chemical induction of conjugation in Paramecium aurelia.

A dominant gene Su(kau-2) partially suppresses the effect of an apparently unlinked recessive kau-2. Gene kau-2 blocks chemical induction of conjugation in Paramecium aurelia syngen 8 when solutions of acriflavine + either KCl or MgCl-2 are used. Wild-type cells are induced to conjugate in either solution. When cells homozygous for kau-2 also have gene Su(kau-2), they are still uninducible in t...

Variation and Inheritance in Abnormalities Occurring after Conjugation in Paramecium caudatum.

Factors Determining Conjugation in Paramecium Aurelia I. the Cyclical Factor: The Recency of Nuclear Reorganization.

N Paramecium aurelia a number of factors interact to determine the I occurrence of conjugation. Most attention has in the past been given to the role of environmental conditions. In this paper an internal factor is dealt with: nuclear reorganization of the type occurring both a t endomixis and a t conjugation. As will be shown, the relation of these nuclear processes to the subsequent occurrenc...
