Effect of the immature cytoplasm on the duration of the interautogamous interval (IAI) in Paramecium tetraurelia.
Cytoplasm in the quantity of about 5% of the cell volume was transferred from young clonal age donors into older recipients. The experimental post-transplantation clones showed statistically significant prolongation of the IAIs as compared with those stemming from the original recipients or donors. This suggests that the cytoplasm of young postautogamous cells contains a component retarding the expression of the autogamy-inducing gene(s).
