Paramecium is a unicellular eukaryote of large size (120 micrometers) that belongs to the ciliate phylum.
Ciliates share two characteristics: the presence of vibrating cilia which assure
their locomotion and food capture, and nuclear dimorphism. Indeed, ciliates,
like multicellular eukaryotes, separate germinal and somatic functions, but they do so in the form
of two different kinds of nuclei. A diploid germinal micronucleus transmits
the genetic information to the next sexual generation, while a polyploid somatic macronucleus is responsible for gene expression.
The Paramecium tetraurelia macronuclear genome was recently sequenced by the Genoscope French National Sequencing Center.
ParameciumDB is a new model organism database associated with the genome sequencing project. Built with core components of the Generic Model Organism Database (GMOD) project, ParameciumDB currently contains the macronuclear genome sequence and annotations, linked to available genetic data (RNA interference data and stock collection).
