Figure 4.

Mitochondrial genome map of Codonopsis, lanceolata. Direction of transcription is represented by the location of the respective genes on the inside (clockwise) or the outside (counterclockwise) of the outermost circle. Inner histogram indicates average coverage depth of reads mapped to the mitochondrial genome sequence (each grey circle represents 60×, with a maximum of 300×). Innermost circle indicates the structural scheme. Repeats of >100 bp are indicated by connecting orange lines and repeats of <100 bp are indicated by connecting blue lines. Tandem repeats are not shown.
