Fig. 3: Inference of WGT events in the ancestors of S. album and S. yasi.

a Distribution of Ks counts for paralogous genes; b Dot plot of DNA sequence alignments across the 10 chromosomes of S. album. Points representing homologous pair locations were colored according to the Ks color scale, and the area delimited in the orange boxes plot the proportional relationship of homologous pairs within a specific region. c Table of gene duplicate types used to infer WGTs; and d detection of whole-genome duplication based on the phylogenomic tree-based method, numbers in the orange box below each node is the number of duplicated gene families/total gene families, with the corresponding green box giving the percentage of (AB)(AB) type duplicates.
