摘要: The complete mitochondrial genome sequence of the marbled rockfish Sebastiscus marmoratus (Scorpaeniformes, Scorpaenidae) was determined and phylogenetic analysis conducted to elucidate evolutionary relationship with other Sebastinae species. This genome, consisting 17301 bp, is highly similar that most vertebrates, containing same gene order an identical number genes or regions, including 13 protein-coding genes, two ribosomal RNAs, 22 transfer one putative control region. Most are encoded on H-strand, while ND6 seven tRNA (for Gln, Ala, Asn, Tyr, Ser (UCA), Glu, Pro) L-strand. reading frame pairs overlapped strand (the ATPase 8 6 by ten nucleotides; ND4L ND4 nucleotides). possibly nonfunctional light-strand replication origin folded into a typical stem-loop secondary structure conserved motif (5′-GCCGG-3′) found at base stem within tRNACys gene. An extent termination-associated (ETAS) blocks (CSB) were identified in region, except for CSB-1; unusual long tandem repeats 3′ end Phylogenetic analyses supported view comprises four genera (Sebastes, Hozukius, Helicolenus, Sebastiscus).
