Genome-scale conservation of synteny among P. tepidariorum scaffolds reveals signatures of an ancient WGD. a Oxford grid displaying the colinearity detected by SatsumaSynteny among the 39 scaffolds presenting the greatest numbers of hits on one another. On this grid (not drawn to scale), each point represents a pair of identical or nearly identical 4096-bp regions. Alignments of points reveal large segmental duplications suggestive of a whole-genome duplication event along with other rearrangements such as inversions, translocations and tandem duplications. b Circos close-ups of some of the colinearity relationships revealed by the Oxford grid
