(Submitter supplied) Paramecium cells in log-phase growth were treated for deciliation and total mRNA extracted at two time points after deciliation. This is usefull to study genes involved in cilia biogenesis. Time points are : T0 : mRNA extracted before deciliation. T30 : mRNA extracted 30 minutes after deciliation. T120 : mRNA extracted 120 minutes after deciliation.

(Submitter supplied) P. tetraurelia, like all ciliates, is a unicellular eukaryote processing two different kinds of nuclei, germline micronuclei (mic) and somatic macronucleus (mac). The diploid micronuclei undergo meiosis during sexual events to transmit the germline genome to the next generation. The highly polyploid mac (~800 n) is responsible for transcription during the life cycle but is lost after fertilisation; the new mic and mac develop from mitotic copies of the zygotic nucleus. more...

(Submitter supplied) In the ciliate Paramecium tetraurelia, autogamy is a self-fertilization process, during which the zygotic nucleus results from the fusion of two identical gametic nuclei. This phenomenon occurs in response to starvation. It starts with meiosis of the germline nuclei (micronuclei or MIC) and fragmentation of the parental somatic nucleus (macronucleus or MAC). This is followed by mitotic division of one haploid nucleus issued from meiosis to yield two identical gametic nuclei, then karyogamy takes place, followed by mitosis of zygotic nucleus and differentiation of new MICs and MACs from the resulting copies of the zygotic nucleus. more...

(Submitter supplied) Paramecium cells possess a few thousand trichocysts (big secretory granules of 3~4 um long) docked at their surface and whose discharge in the external medium can be triggered using aminoethyldextran (a modified dextran positively charged) without damage to the cells. After discharge, new trichocysts are re-synthesized by the cells. We studied the evolution of the transcriptome during this synthesis.

(Submitter supplied) At each sexual cycle, during development of the somatic macronucleus (MAC) from the germline micronucleus (MIC), the genome of the ciliate Paramecium tetraurelia is massively rearranged through the reproducible elimination of germline-specific sequences. It has been reported previously that targeting of these sequences is mediated by non-protein-coding RNAs including different classes of small RNAs and longer non-coding transcripts. more...
