    ...of mature MACs (about 800C to 1600C in Paramecium tetraurelia) (Preer 1976). Concomitantly with amplification, programmed DNA elimination (PDE) removes ∼30% of germline DNA from the new MAC , going from a 98- to 151-Mbp haploid size in the MIC to 72–75 Mbp in the mature MAC (Aury et al. 2006; Guérin et al...

    ...eliminate tens of thousands of DNA sequences from a germline copy. Recently, we showed that the chromatin remodeler ISWI1 is required for somatic development in the ciliate Paramecium tetraurelia. Here, we describe two high similarity paralogous proteins, ICOPa and ICOPb, essential for their editing. ICOPa...

    ...that environmentally induced developmental thermoplasticity contributes to genotypic diversification in Paramecium.The DNA that is perpetuated by the germline is not always carried over to the soma in its entirety. In a broad range of eukaryotes, germline DNA sequences are reproducibly discarded at each round...

    ...with high splicing efficiency. Our data reveal a complex link between GC content, nucleosome positioning, and intron evolution in Paramecium.In eukaryotes, genomic DNA is compacted by histones into chromatin. The basic unit of chromatin is the nucleosome, which comprises a histone octamer made of the four...
