Schematic of C. cohnii mtDNA fragments. Mitochondrial sequences are drawn to scale, with coding sequence on either the forward or reverse strand indicated above or below the line, respectively. Colored blocks indicate protein-coding genes and hatched boxes denote rRNA genes. Coding sequence is identified by sequence similarity to gene homologues irrespective of standard start and stop codons. Common sequence between fragments (> 99% identity) is indicated by horizontal dashed lines and matching lowercase letters. Black boxes indicate locations and sizes of Southern blot probes. Large inverted repeats (> 9) are indicated by black dot pairs above and below each sequence, and short proximal inverted repeats (> 6) are indicated by paired vertical dashes. Minor differences of inverted repeat distribution between common sequence (dashed lines) are due to the minor sequence differences.
