title: Complete mitochondrial genome of the miiuy croaker Miichthys miiuy (Perciformes, Sciaenidae) with phylogenetic consideration.
abstract: The complete sequence of the 16,493 nucleotide mitochondrial genome from the single species of the family Sciaenidae, the miiuy croaker, Miichthys miiuy, was determined. The nucleotide sequences of M. miiuy mitochondrial DNA have been compared with those of three other Sciaenidae fishes. The contents of the M. miiuy mitochondrial genome are 13 protein-coding genes, two ribosomal RNA genes and 22 transfer RNA genes, and two non-coding regions (L-strand replication origin and control region), the gene order of which is identical to that observed in most vertebrates. The L-strand replication origin of M. miiuy is not pyrimidine-rich compared to those of most bony fishes. Within the control region, we identified the extended termination associated sequence domain, the central conserved sequence block domain and the conserved sequence block domain, while the typical central conserved blocks CSB-D, -E and -F could not be detected in the three other Sciaenidae species. In the ML phylogenetic analyses, the monophyly of Pseudosciaeniae was not supported, which is against with the morphological results. Collichthys niveatus is most closely related to Larimichthys polyactis, and Collichthys and Larimichthys may be merged into one genus, based on the current datasets.
