Fraction of shared plant-animal intron positions in each fungal species. Among the 501 intron positions that are shared between A. thaliana and a vertebrate (and thus likely present in the fungus-animal ancestor), the fraction that is shared with each fungal species is given. Color coding is lavender: introns found only within the clade or a single species, maroon: introns shared only with other fungi,, pink: introns shared with animals, green: introns shared with plants (A. thaliana), brown: introns shared with animals or plants.
