The complete mitochondrial genome of Gruberia lanceolata (Gruber, 1884) Kahl, 1932 (Ciliophora: Heterotrichea).

The ciliate Gruberia lanceolata (Gruber, 1884) Kahl, 1932 belonging to the class Heterotrichea was sampled from the coastal waters of South Korea. The complete mitogenome in its linear form and large size (∼40 kb) was obtained. It consisted of 27 protein-coding genes (PCGs), two ribosomal subunit RNA (rRNA) genes, four transfer RNAs (tRNAs), and ten unclassified open reading frames (ORFs). Their telomeric structures were capped, with repeat regions at both ends. We analyzed its phylogenetic tree using the data of its respiratory chain complex I genes. It can be suggested that the complete mitochondrial genome of G. lanceolata can be recorded as a new class of the mitogenome.
