The genomes of three representative Polyporales (Bjerkandera adusta, Phlebia brevispora and a member of the Ganoderma lucidum complex) were sequenced to expand our knowledge on the diversity of ligninolytic and related peroxidase genes in this Basidiomycota order that includes most wood-rotting fungi. The survey was completed by analyzing the heme-peroxidase genes in the already available genomes of seven more Polyporales species representing the antrodia, gelatoporia, core polyporoid and phlebioid clades. The study confirms the absence of ligninolytic peroxidase genes from the manganese peroxidase (MnP), lignin peroxidase (LiP) and versatile peroxidase (VP) families, in the brown-rot fungal genomes (all of them from the antrodia clade), which include only a limited number of predicted low redox-potential generic peroxidase (GP) genes. When members of the heme-thiolate peroxidase (HTP) and dye-decolorizing peroxidase (DyP) superfamilies (up to a total of 64 genes) also are considered, the newly sequenced B. adusta appears as the Polyporales species with the highest number of peroxidase genes due to the high expansion of both the ligninolytic peroxidase and DyP (super)families. The evolutionary relationships of the 111 genes for class-II peroxidases (from the GP, MnP, VP, LiP families) in the 10 Polyporales genomes is discussed including the existence of different MnP subfamilies and of a large and homogeneous LiP cluster, while different VPs mainly cluster with short MnPs. Finally, ancestral state reconstructions showed that a putative MnP gene, derived from a primitive GP that incorporated the Mn(II)-oxidation site, is the precursor of all the class-II ligninolytic peroxidases. Incorporation of an exposed tryptophan residue involved in oxidative degradation of lignin in a short MnP apparently resulted in evolution of the first VP. One of these ancient VPs might have lost the Mn(II)-oxidation site being at the origin of all the LiP enzymes, which are found only in species of the order Polyporales.
