Numerous studies based on analysis of their morphology and genetic makeup frequently provided controversial results. In the present work, we sequenced complete mitochondrial (mt) genomes and fragments of nuclear ribosomal DNA (rDNA) of the fourhorn sculpin <span class=\"html-italic\">Myoxocephalus quadricornis</span> and some related cottids to increase the power of phylogenetic and taxonomic analyses of this complex fish group. A comparison of the <span class=\"html-italic\">My. quadricornis</span> mt genomes obtained by us with other complete mt genomes available in GenBank has revealed a surprisingly low divergence (3.06 ± 0.12%) with <span class=\"html-italic\">Megalocottus platycephalus</span> and, at the same time, a significantly higher divergence (7.89 ± 0.16%) with the species of the genus <span class=\"html-italic\">Myoxocephalus</span>. Correspondingly, phylogenetic analyses have shown that <span class=\"html-italic\">My. quadricornis</span> is clustered with <span class=\"html-italic\">Me. platycephalus</span> but not with the <span class=\"html-italic\">Myoxocephalus</span> species. Completely consistent patterns of divergence and tree topologies have been obtained based on nuclear rDNA. Thus, the multi-gene data in the present work indicates obvious contradictions in the relationships between the <span class=\"html-italic\">Myoxocephalus</span> and <span class=\"html-italic\">Megalocottus</span> species studied. An extensive phylogenetic analysis has provided evidence for a closer affinity of <span class=\"html-italic\">My. quadricornis</span> with the species of the genus <span class=\"html-italic\">Megalocottus</span> than with the species of the genus <span class=\"html-italic\">Myoxocephalus</span>. A recombination analysis, along with the additional GenBank data, excludes introgression and/or incorrect taxonomic identification as the possible causative factors responsible for the observed closer affinity between the two species from different genera. The above facts necessitate realignment of the genera <span class=\"html-italic\">Myoxocephalus</span> and <span class=\"html-italic\">Megalocottus</span>. The genetic data supports the two recognized genera, <span class=\"html-italic\">Myoxocephalus</span> and <span class=\"html-italic\">Megalocottus</span>, but suggests changing their compositions through transferring <span class=\"html-italic\">My. quadricornis</span> to the genus <span class=\"html-italic\">Megalocottus</span>. The results of the present study resolve the relationships within a complex group of sculpin fishes and show a promising approach to phylogenetic systematics (as a key organizing principle in biodiversity research) for a better understanding of the taxonomy and evolution of fishes and for supplying relevant information to address various fish biodiversity conservation and management issues.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Genetic evidence for a mixed composition of the genus <i>Myoxocephalus</i> (Cottoidei: Cottidae) necessitates generic realignment","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"mitochondrial genome, ribosomal DNA, COI, genetic divergence, fourhorn sculpin, belligerent sculpin, taxonomic realignment ","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-11-24","DateCreate":"2020-11-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000580155400001","VABBcode":null,"OpenAcc":1,"DOI":"10.3390/genes11091071"},"refs":null,"anarec":{"AnaID":331300,"PubliDate":2020,"Pagination":"1071","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":268585,"SerRR":"Genes.
