Extended Data Fig. 1: Single copy orthologs gene sets.

Representation of intersects across single-copy ortholog gene sets (that is, the four PSO, DSO and ASO) using UpSetR. Bars represent the number of genes in the intersect represented below the histogram. PSO: pairwise single-copy orthologs. DSO: dioicous single-copy orthologs. ASO: All species single-copy orthologs. If we consider for instance the line ‘S.fir-C.lin’, a set of 4125 orthologs are found within PSOs, 3211 are also found in the DSO set, 899 are also members of both the DSO and ASO gene sets and, finally, 22 orthologs are present in the ASO only. Note that the orthofinder analysis was performed independently for DSO and ASO (see methods), therefore some ASOs do not overlap with DSO.
