Statistical genome analysis of Ascomycota and Basidiomycota. a Principal component analysis (PCA) of genes encoding AA9 LPMOs, AbPPOs, and MtPPO7s of 336 Ascomycota and 208 Basidiomycota genomes. The numbers which describe the presence of genes encoding AA9 LPMOs, MtPPO7s, and AbPPOs in each fungal species were used as variables and are presented as principal components of Ascomycota (red dots) and Basidiomycota (blue dots). The first two components of the PCA explained 69.8 and 19.6% variation in the data, respectively. Vectors (red arrows) with a similar orientation illustrate a high correlation between the gene families (b). The axis legends indicate the overall contribution of the three gene families encoding AA9 LPMOs, AbPPOs, and MtPPO7s. b Correlation between the three gene families encoding AA9 LPMOs, AbPPOs, and MtPPO7s of 336 Ascomycota (upper triangle) and 208 Basidiomycota (lower triangle). c Correlation between genes encoding AA9 LPMOs, AbPPOs, and MtPPO7s of 27 Ascomycota (upper triangle) and 23 Basidiomycota (lower triangle), which have at least ten annotated genes encoding cellulose-degrading enzymes per fungus. Species of both fungal classes are listed in Additional file 7: Table S2 and Additional file 8: Table S3. Numerical values of the correlations of b and c are presented in Additional file 9: Figure S6. See “Methods” for details
