Plastome map of<i>Catharanthus</i><i>roseus</i>.

<p>The within-plastome GC content variation is indicated in the inner circle. Positions of simple sequence repeats (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0068518#pone.0068518.s003" target="_blank">Table S3</a>) are drawn as lines vertical to the inner circle (color-coded by repeat length; 1-bp: red; 2- or 3-bp: blue; 4- or 5-bp: green). Genes drawn inside the outer circle are transcribed clockwise, those outside counterclockwise. Pseudogenes (Ψ) and genes containing one (*) or two (**) introns are indicated. Five intergenic regions of potential phylogenetic utility are indicated by hollow triangles outside of the outer circle.
