Fig. 1

The complete mitochondrial genome of Echinococcus granulosus (sensu stricto) genotype G1. The 12 protein-encoding genes, 2 rRNAs and 21 tRNAs (except tRNA-Gly) are depicted in light grey; the non-coding region NR1 is in darker grey. Transfer RNAs are designated by one-letter amino acid abbreviations; gene designations follow Le et al. [83]. The tandem repeat region (in four shades of brown) spans 4417 bp and includes 10 repeat units. Each unit contains the 3′-end of nad5, the non-coding region NR2, tRNA-Gly (proposed pseudo-tRNAs in repeat units 1–9), 3 bp-intergenic region (not shown on figure) and 5′-end of cox3. Repeat units 2–9 are identical, whereas units 1 and 10 each have a 3–4 nucleotide insertion, marked by an asterisk. The TTT insertion occurs in repeat unit 1, at the 3′-end of nad5, the TTTT insertion occurs in repeat unit 10, in tRNA-Gly. Secondary structures of NR1 (a) and NR2 (b) are shown at the top; parts of these structures are predicted to have hair-pin loops with no mis-matches - depicted in green (stem) and yellow (loop); mis-matches are boxed
