NUMT distribution in three cnidarian mitochondrial genomes. (A) NUMT distribution in the A. digitifera mitochondrial genome. The mtDNA genome contains the genes for 13 energy pathway proteins, two rDNAs and two tRNAs. A single intron occurs in the ND5 gene. Note that the intron occurs within the ND5 gene and contains the only copies of the tRNA-Trp, ATP8, COX1, tRNA-Met, and l-rRNA genes. The black line represents the only NUMT in the A. digitifera genome. (B) NUMT distribution in the N. vectensis mitochondrial genome. A single intron occurs in the ND5 gene. Note that the intron occurs within the ND5 gene and contains the only copies of the ND1 and ND3 genes. Each black line represents a NUMT insertion in the reference genome. (C) NUMT distribution in the H. magnipapillata mitochondrial genome. For clarity, the NUMTs whose length is longer than 500 bp are indicated with black lines.
