Figure 1
Genetic map of the M-type Donax vittatus mitogenome. The presented features follow the convention of mitoconstricor (https://github.com/aburzynski/mitoconstrictor). Outer blue line represents sequence coverage with sequencing reads (grey circles 10 × and 100 × coverage). Arrows represent identified genes, tRNAs and open reading frames. Orange ovals on arrows represent identified transmembrane domains. Transparent light-gray boxes represent repetitive sequences in non-coding region. Sequence local compositional bias is represented by inner circles, calculated in a 200 bp long sliding window with 25 bp steps. First inner green circle represents local AT-skew; blue circle represents local GC-skew; red circle represents local GC content relative to average of the whole mitogenome. Red line represents filtered AT-skew at non-coding regions, and second codon position. Black and two green lines represent filtered AT-skew, GC-skew and GC content respectively, at neutral sites, calculated in a 1.000 bp long sliding window. Genetic maps for all three mitogenomes with cartoon legend can be found in supplementary data.
