Fig. 1From: Complete mitochondrial genomes and nuclear ribosomal RNA operons of two species of Diplostomum (Platyhelminthes: Trematoda): a molecular resource for taxonomy and molecular epidemiology of important fish pathogensSchematic alignment of linearised mt genomes of Diplostomum spathaceum and D. pseudospathaceum. Outline arrows indicate the direction of transcription of protein-coding and rRNA genes, hairline arrows indicate the position of tRNA genes (see Additional file 4: Table S1 for the single letter abbreviations). Solid horizontal lines in the grey central area depict average nucleotide identities of individual protein- and rRNA-coding regions (the ‘barcode’ region of cox1 defined by Folmer primers indicated by a dotted line); NC non-coding regionBack to article page
