Map of the plastid genome of Hypericum ascyron. A Graph showing the base per base depth of the sequencing coverage across the H. ascyron plastome with one inverted repeat (IR) region. B Genes on the inside and outside of each map are transcribed in the clockwise and counterclockwise directions, respectively. The thick lines on the plastid map indicate the inverted repeats (IRA and IRB) that separate the genome into large and small single-copy regions. Ψ denotes a pseudogene. Red arrows indicate expansion events. Colored arcs on the outside of the map correspond to the locally collinear blocks inferred by Mauve (see Fig. 4)
