Intron length versus average number of introns per kilobase. Colored boxes indicate the fungal clade as shown in Figure 1: red, Hemiascomycota; yellow, Archiascomycota; green, Euascomycota; orange, Zygomycota; blue, Basidiomycota; purple, basidiomycete U. maydis. Bars indicating standard deviation in intron length are drawn but only visible for the intron-poor species. CDS, coding sequence.
