Figure 2.

Comparison of the plastid genome regions comprising genes rpl33, rps18, and rpl20 for D. rotundifolia, D. erythrorhiza, and F. esculentum. Regions between the start of rpl33 and the start of the counter-oriented rpl20 are shown; coordinate numbering for each plastome starts from the beginning of gene rpl33. Genes are indicated by rectangles with arrowheads. Black triangles within the orf641 rectangle indicate 73 copies of the 21 bp-long repeat sequence coding for a peptide with GQKQPNI consensus in D. rotundifolia. The part of orf641 that corresponds to the rps18 sequence is indicated in blue. The central part shows alignment in Mauve; pink areas between D. rotundifolia and D. erythrorhiza sequences highlight homologous regions. Note that the Mauve profile obtained for D. erythrorhiza has been turned upside down for clarity of presentation.
