Figure 5.

Diagram showing the karyotypes of five Helianthus taxa as well as reconstructed ancestral karyotypes and the locations of chromosomal rearrangements. The karyotypes were built using synteny block set 1, and were curated based on multiple syntR runs and inferred when missing. Each synteny block is represented using a line segment that is color-coded based on its position in the H. annuus genome (see Figure S14 for a labeled version). Chromosomes without translocations in any map are plotted in gray, and synteny blocks that are inverted relative to H. annuus are plotted using arrows. Also, note that along some branches the same pair of chromosomes is involved in multiple translocations.
