Distribution of genes for each AA11 subfamily in the genomes of ascomycetes. The number of genes encoding proteins belonging to each AA9 subfamily was counted for each genome. A. Plant cell wall-degraders are indicated by “yes” and non-degraders are indicated by “no”. B. Dermatophytes are indicated by “dermatophyte” and non-invaders are indicated by “other ascomycete”. The classification of fungi as plant cell wall-degraders, non-degraders, dermatophytes and other ascomycetes is described in “Methods” and in Additional file 4.
