Figure 3. Linear representation of the gene order and t/rRNA locations in seven Pulmonata mollusc species.

Mitochondrial genomes scaled to 100%. tRNAs are encoded in single letter code according to the amino acid they represent: A, Ala; G, Gly; P, Pro; T, Thr; V, Val; S, Ser; R, Arg; L, Leu; F, Phe; N, Asn; K, Lys; D, Asp; E, Glu; H, His; Q, Gln; I, Ile; M, Met; Y, Tyr; C, Cys; W, Trp). Boxes with shadow represent the reverse direction.
