1MAC and MIC genomes of T. thermophila are previously published data (TGD Wiki, http://ciliate.org). All other genomes are newly sequenced.
2Draft MIC genome of T. malaccensis was sequenced by Pacbio SMRT sequencing technology; the N50 value refers to contig length.
Abbreviations: GC, Guanine and Cytosine; MAC, macronucleus; MIC, micronucleus; N50, the sequence length of the shortest contig at 50% of the total genome length; NA, not available; SMRT, single-molecule real-time; TGD, Tetrahymena Genome Database.
