In ciliates, unicellular representatives of the bikont branch of evolution, inter- and intracellular signalling pathways have been analysed mainly in Paramecium tetraurelia, Paramecium multimicronucleatum and Tetrahymena thermophila and in part also in Euplotes raikovi. Electrophysiology of ciliary

In Paramecium, the regeneration of a functional somatic genome at each sexual event relies on the elimination of thousands of germline DNA sequences, known as Internal Eliminated Sequences (IESs), from the zygotic nuclear DNA. Here, we provide evidence that IESs' length and sub-terminal bases jointl

Phenotypic variation of a single genotype is achieved by alterations in gene expression patterns. Regulation of such alterations depends on their time scale, where short-time adaptations differ from permanently established gene expression patterns maintained by epigenetic mechanisms. In the ciliate
