Fig 1. Phylogenetic tree of P450s belonging to basidiomycete biotrophic plant pathogens and non-pathogens used in this study as listed in Table 1.

The branches with different colours show their taxonomy, as indicated in the legend. Ancestral branches with children that had identical colours were assigned the same colour as the children. The outer numbers indicate the eight clades, and their ranges are marked by alternating red and black. Each P450 is presented with its family and subfamily following its protein ID (parenthesis). A high-resolution phylogenetic tree is provided as S1 Fig.
