Basic bioinformatical analysis of the draft Euplotes crassus macronuclear genome and transcriptome suggests that more than a quarter of E. crassus genes contain several exons. A large fraction of all introns is formed by "tiny" introns having length 20-30 bp. Analysis of the transcriptome revealed 63 possible cases of alternative splicing, and also 14 introns with non-standard splicing sites. About 2000 hypothetical genes do not have homologs in other ciliates, and since most of them have the closest homologs in bacterial genomes, they are likely an artifact of the sample preparation. Comparison of the E. crassus genome to the genomes of other ciliates showed an expansion of the same gene families, responsible for the free-living heterotrophic lifestyle.
