ψND5 element positions in C. briggsae mitochondrial genomes. Dashed boxes indicate the two ψND5 elements and open boxes indicate mtDNA genes. Protein-coding genes are indicated by their common abbreviations and tRNA genes are indicated by their respective associated single-letter amino acid codes. ψND5-1 is 214–223 bp, depending on isolate, and ψND5-2 is 325–344 bp. The dashed horizontal line on top indicates DNA sequences that are lost in heteroplasmic ND5 deletion variants and the arrows indicate the primer positions that are employed for conventional PCR assays.
