Abstract

Tetrahymena rostrata is a ciliated protist which can parasitize the gray field slug, Deroceras reticulatum. Here, we report the sequence of the mitochondrial genome (mt genome) of a strain of T. rostrata that was isolated from the egg of D. reticulatum. Whole cell genomic DNA was sequenced using Illumina^® MiSeq and the mitochondrial DNA sequence reads were extracted and assembled. The resulting 47,235 bp assembly contained rRNAs, tRNAs, and 45 protein coding DNA sequences of which 21 encoded proteins of unknown function. Phylogenetic analysis showed T. rostrata clustered with Tetrahymena thermophila, Tetrahymena pigmentosa, Tetrahymena pyriformis, Tetrahymena paravorax, and Tetrahymena malaccensis.
