First complete mitochondrial genome from family Moinidae, Moina macrocopa (Straus, 1820) (Cladocera; Moinidae).

ABSTRACT: We sequenced and annotated the complete mitochondrial genome for the freshwater water flea Moina macrocopa (Straus, 1820). This is the first mitogenome for the family Moinidae. The complete mitogenome of M. macrocopa is 16,072 bp, with 35.8% A, 17.6% C, 12.8% G, and 33.8% T. The mitogenome comprises 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a non-coding region. Phylogenomic analysis based on 28 in-group taxa belonging to the orders Anostraca, Diplostraca, and Notostraca is congruent with published phylogenetic relationship for cladocerans, with M. macrocopa being grouped with members of the Daphniidae. This mitogenome resource will be useful for future phylogenetic studies of water fleas.

Project description:BackgroundMitochondrial (mt) genome sequences are widely used to understand phylogenetic relationships among parasites. However, no complete mt genome sequence is available in the family Anoplocephalidae to date. This study sequenced and annotated the complete mt genome of Anoplocephala perfoliata (Anoplocephalidae), and investigated its phylogenetic relationships with other species from the families Hymenolepididae, Dipylidiidae and Taeniidae of the order Cyclophyllidea using the amino acid sequences of the 12 proteins in their mt genomes.MethodsThe complete mt genome of A. perfoliata was amplified by Long-range PCR, sequenced using primer walking and annotated by comparing with those of other cestodes. Its phylogenetic relationship with the species from the families Hymenolepididae, Dipylidiidae and Taeniidae was inferred using the 12 protein sequences based on Maximum likelihood and Bayesian methods.ResultsThe complete circular mt genome sequence for A. perfoliata is 14,459 bp in size, and includes 12 protein-coding genes, 2 rRNA genes and 22 tRNA genes. The mt gene arrangement of A. perfoliata is identical to those of previously reported Hymenolepis diminuta (Hymenolepididae) and Dipylidium caninum (Dipylidiidae), but slightly different from those of other taeniids due to an order switch between tRNA(S2) and tRNA(L1). The phylogenetic analyses showed that the Dipylidiidae was more closely related to Anoplocephalidae and Hymenolepididae than to Taeniidae. The relationship among the four families obtained by Maximum likelihood and Bayesian inferences based on predicted amino acid sequences of protein-coding genes is consistent with that based on their mt gene arrangement similarities.ConclusionsThis study determined the first mt genome for the family Anoplocephalidae, providing rich sources for selecting useful molecular markers for ecological and phylogenetic studies. Analyses on mt genome sequences of the four families of cestodes provide novel insights into their phylogenetic relationships. Of course, more taxon sampling is necessary for future phylogenetic studies of these cestodes using mt genome sequences.
