FIG. 3. — Evolution of peroxidases genes in fungi. A, known phylogeny of the major taxa of fungi; squares show the colors used in the phylogenetic tree; B, presence of the different families of peroxidases in the major fungal taxa: -, absent; +, few taxa (<10%); ++, many taxa (10-60%) having relevant peroxidase genes; +++, most taxa (> 60%) having relevant peroxidase genes. Numbers in parenthesis are the minimum and maximum numbers of genes detected in genomes of relevant taxa. C, phylogenetic tree of haloperoxidases. Tree was rooted with proteins from bacteria. Dots at the end of the protein names indicate the presence of a secretion signal predicted by SignalP (in blue), Predisi (in green) or both (in red). The P. anserina (Rabenh.) Niessl protein is in red.
