Orthogroups and functional gene categories in Zymoseptoria spp. genomes. a Orthogroups shared by the reference Z. tritici genome, our new Zymoseptoria assemblies and the outgroup genome of C. beticola. Only intersects higher than 100 are displayed on the upset plot. The doughnut plot summarizes the number of orthologs grouped by larger categories: specific to some isolates, to a species or shared by all. The colored bars under the upset plot link each intersect to its corresponding category in the doughnut plot. b Venn diagram representing the genes shared by the three isolates of Z. tritici. c The only gene category found to be overrepresented in any of the specificity categories - other than unknown function genes - are predicted effector genes. Predicted effectors genes are overrepresented in the genus-specific genes and in Z. ardabiliae specific genes (*** represent Fisher exact test p-value < 0.05)
