Plastome map of <i>Ardisia polysticta</i>.

<p>Genes drawn inside the circle are transcribed clockwise, those outside counterclockwise. The within-plastome GC content variation is indicated in the middle circle. Pseudogenes (Ψ) and genes containing one (*) and two (**) introns are indicated. Regions of potential phylogenetic utility (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0062548#pone-0062548-t002" target="_blank">Table 2</a>) are indicated by hollow triangles outside the circle (numbered from more to less divergent). Numbers and locations of repetitive sequences (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0062548#pone-0062548-t004" target="_blank">Table 4</a>) are drawn on the four inner circles (from inside: dispersed direct repeats (forward triangles), inverted repeats (forward and reversed triangles), tandem repeats (tandem triangles), palindromic sequences and a sequence that matches its reversed sequence (hexagrams)).
