Figure 2

The distribution of repeat sequences at 30 loci in Amaranthus. “R” is short for repeat. The red line segment R12 and the black line segments are repeats in all 17 species, the orange line segment represents a repeating sequence in some species. A repeat with only one line segment indicates that there is only one repeat at the site, and vice versa indicates that there are several different repeats at the site. The chloroplast genome figure was generated by the Geneious Prime v. 2020.1.2 software.
