...Maria Jerka-Dziadosz; Françoise Ruiz; Janine Beisson ABSTRACT In Paramecium the development of cell shape and surface pattern during division depends on a precise spatial and temporal pattern of duplication of the ciliary basal bodies which are the organizers of the cortical cytoskeleton. According...

...M. Rosario Romero; Antonio Torres ABSTRACT The cortical cytoskeleton of Paramecium is character-ized by a complex, polarized and asymmetrical organi-zation. In order to analyse the cortical development of Paramecium tetraurelia during the sexual process of con-jugation, different antibodies have...

...Francine Iftode; Jean Cohen; Françoise Ruiz; Antonio Torres Rueda; Lily Chen-Shan; André Adoutte; Janine Beisson ABSTRACT The shape of a Paramecium is determined by the organization of its cortex which constitutes most of the cell cytoskeleton. These structures and networks are organized...

...M. F. Chau; Stephen F. Ng The micronucleus of Paramecium plays an essential role in the development of the oral apparatus in both asexual and sexual cycles. The present study analyses this somatic function of the micronucleus by interspecific transplantation of the micronucleus between two species...

...Stephen F. Ng Paramecium tetraurelia normally resorbs the preexisting oral apparatus (and develops a new one) during sexual reproduction. Violation of this rule was found in amicronucleate cell lines. These cell lines generated chains of two cells (homopolar tandems) at a low frequency, as a result...
