Table 1 Mapping results of Nanopore long reads to the four possible configurations associated with three DBS (DBS01–03) of the S. splendens mitogenome, which correspond to repetitive sequences (R01, R04, and R07).

  1. The percentage of minor DBS configurations was calculated as the number of reads mapped to the configurations having fewer mapped reads divided by those mapped to all configurations.
  2. DBS double-bifurcation structure, MC1/2 mitogenome chromosome 1/2.
  3. aValidated successfully with PCR.
  4. ball positions are based on MC1, except those marked with MC2.
