Intraspecific intron content polymorphism in Colletotrichum fructicola. The intron presence-absence patterns of 15 surveyed isolates, together with the nucleotides of these isolates at five polymorphic sites within a 762 bp long alignment of ApMAT locus DNAs are shown. The intron content of the C. aenigma isolate XY15 is shown as a comparison. GenBank accessions of the ApMAT locus sequences are listed in Additional file 1: Table S1
