Figure 1.

Gene map of the Echinacea purpurea chloroplast genome. Genes shown outside the circle are transcribed clockwise and those inside are transcribed counterclockwise. Gene belonging to different functional groups are color-coded as indicated by icons on the lower left corner. Dashed area in the inner circle indicates the GC content of the chloroplast genome. LSC, SSC and IR means large single copy, small single copy and inverted repeat, respectively.
