Striking cloverleaf secondary structures of several tRNAs and tRNA-like structures deduced from the complete sequence of the five mitochondrial genomes sequenced in this study. A, B, and C show three proposed cloverleaf secondary structures found in the mt genome of P. dolabrata. Boxes in A, B, and C indicate the overlapping nucleotides of these tRNAs with their downstream genes (cox1, trnF, and trnC, respectively). Note that the nucleotide sequences of the trnY (A) and trnK of P. dolabrata (B) are almost identical. A truncated TψC stem is shown in the trnQ of P. dolabrata (C). D and E indicate potential secondary structures found in the longest non-coding region of the mt genome of O. celtica. F and G show several proposed cloverleaf secondary structures found in the mt genome of M. myosotis and S. pectinata respectively. Boxes in F and G show the overlapping nucleotides between trnY and trnW in M. myosotis (F) and between trnG and trnC in S. pectinata (G).
