Xie, Y-Y Chen, H-X Kuzmina, T A Lisitsyna, O Li, L Genome, Mitochondrial Animals Phylogeny Acanthocephala Sequence Analysis, DNA RNA, Transfer Species of the genus (Acanthocephala: Polymorphida) mainly parasitize marine mammals and rarely marine birds, and are of veterinary and medical importance due to causing corynosomiasis in wildlife and humans. However, the current knowledge of the mitochondrial genomes and mitogenomic phylogeny of this group remains very insufficient. In the present study, the complete mitochondrial genomes of (von Linstow, 1892) and Zdzitowiecki, 1984 were sequenced and annotated for the first time. Both mitogenomes comprise 12 protein-coding genes (missing ), 22 tRNA genes, and 2 ribosomal RNAs ( and ), plus 2 non-coding regions ( and ). has the largest mitogenome (14,879 bp) of any polymorphid species reported so far, while has the smallest (13,947 bp), except for (Petrochenko, 1949). Comparative mitogenomic analysis also revealed the presence of distinct discrepancies in A + T content and gene rearrangement across the families Polymorphidae, Centrorhynchidae, and Plagiorhynchidae. Moreover, phylogenetic analyses based on the concatenated amino acid sequences of 12 protein-coding genes strongly supported the monophyly of the order Polymorphida and a close affinity between the families Polymorphidae and Centrorhynchidae in Polymorphida. The present mitogenomic phylogeny provides additional evidence for a sister relationship between the genera and and demonstrated that has a closer relationship with than in the genus |
