Number of reciprocal best BLAST hits between subsets of the five Yarrowia-like yeast genomes. Plots were visualized using R package UpSetR [28] The core genome of all five YLY strains includes 5784 genes (90.3%). Clade I genomes share 410 genes and the clade II genomes share 581 genes. Aside from the core genome, no other subset of the diagram includes as many genes as the clade specific subsets. This indicates that genes in the clade I genomes C11 and E02 are more closely related to each other than the other genomes, which is also true for the three clade II genomes B02, F05 and H10. Furthermore, this comparison shows that clade I genomes (C11, E02) have more strain-specific genes than the clade II genomes (B02, F05, H10).
