Immaturity substances: material basis for immaturity in Paramecium.
نویسندگان
چکیده
Cells of Paramecium caudatum in the immaturity period of the life cycle contain substances which repress the expression of mating ability when introduced into mature cells. When 5 x 10 /tm of immature cytoplasm were injected into mature cells, loss of mating ability occurred and it continued for more than 15 fissions after the injection. The effective substances are contained in the soluble fraction of immature cells and have the properties of heatlabile macromolecules.

Immaturity substances in Paramecium primaurelia and their specificity.
Cells of Paramecium primaurelia in the immaturity period of the life cycle contain substances which repress the expression of mating ability when introduced into mature cells. When the immature cytoplasm of P. primaurelia was injected into mating-reactive cells of P. tetraurelia, P. caudatum and P. multimicronucleatum, immaturity was also induced in them. But the immature cytoplasm of P. primau...
متن کاملNovel features of computer-simulated clonal life of Paramecium caudatum.
The clone of the ciliated protozoan Paramecium caudatum has the immaturity period of about 60 fissions and the lifespan of about 600 fissions. These life cycle figures have been depicted through laboratory experiments that allow continuous cell divisions for hundreds, which never occur in nature. We here constructed the nature-mimicking model culture that alternated the log- and stationary phas...
متن کاملDestruction of immaturin activity in early mature mutants of Paramecium caudatum.
Cells of Paramecium in the sexually immature period of the clonal life cycle contain a protein called immaturin, which represses mating activity when injected into sexually mature cells. The amount of immaturin at various stages of the immaturity period was examined by injecting cytoplasm from immature cells of one wild-type and two early mature mutant clones into mature cells of wild-type. The...
