Fig. 6. Colocalization frequency of interchromosomal paralogs retained after WGD and comparison of DNA methylation modification differences between colocalized and noncolocalized paralogs.

a Colocalized interchromosomal paralog pairs in P. euphratica (left) and P. alba var. pyramidalis (right). The orange dashed lines indicate the observed colocalization frequencies for paralogs retained after WGD. The blue curves show the colocalization frequency distributions for 1000 randomizations of the same number of pairs as in the real data. b Box plots of the absolute difference in DNA methylation modification levels (CG, CHG, and CHH) between colocalized paralogs and between noncolocalized paralogs after WGD in P. euphratica and P. alba var. pyramidalis
