Circular map of the mitochondrial genome of Lineus viridis and stem-loop structure of the control region. tRNA genes are represented by their corresponding amino acid one letter abbreviation. Except trnT and trnP all genes are on the same strand and are oriented (5'-3') in clockwise manner. Numbers (+/-) depict noncoding nucleotides between genes or overlapping nucleotides, respectively. The stem-loop structure is annotated minus-strand like, to show signal sequences (boxed) similar to that found in arthropod control region. The depicted region correspondes to c14260 – c14150 of the GenBank record.
