Figure 1.

Gene map of four Notopterygium species. Genes lying outside of the outer layer circle are transcribed in the counter clockwise direction, whereas genes inside are transcribed in the clockwise direction. The colored bars indicate known different functional groups. The darker gray area in the inner circle denotes GC content while the lighter gray corresponds to AT content of the genome. LSC: large single copy, SSC: small-single-copy, IR: inverted repeat.
