FIGURE 1.

Plastome map of Ambrosia trifida. Gene features and distribution of the direction of genes with respect to their localization. Genes on the inner side of the outer circle are transcribed counterclockwise while those on the outer side are transcribed clockwise. Genes belonging to different functional groups are color-coded; the GC and AT content of the genome are plotted on the inner circle as dark and light gray, respectively. Inverted repeats (IR); large single copy (LSC) regions; small single copy (SSC) regions.
