Phylogenetic relationships of Russian far eastern flatfish (Pleuronectiformes, Pleuronectidae) based on two mitochondrial gene sequences, Co-1 and Cyt-b, with inferences in order phylogeny using complete mitogenome data.
2016
AbstractThe systematics and phylogeny of flatfish is investigated on the complete sequence of nucleotides at subunit 1 cytochrome c oxidase (Co-1) and cytochrome b (Cyt-b) genes. In total 17 species from our collection and some species from GenBank were analyzed. Four types of trees were built: Bayesian (BA), maximum likelihood (ML), maximum parsimony (MP), and neighbor joining (NJ). These trees showed similar topology. Two separate clusters on the trees support subfamily Hippoglossoidinae and Hippoglossinae subdivision and monophyletic status of these taxa. The subfamily Pleuronectinae also can be considered monophyletic, if the tribe Microstomini is excluded from it and genus Lepidopsetta is moved into the tribe Pleuronectini. Mitogenomes represented by 25 complete sequences from NCBI GenBank were analyzed. After alignment two sets of nucleotide sequences were formed and investigated independently. One set included 13 structural genes (14,886 bp), the second set comprised by the mtDNA without ND6 gene (...
