Figure 1.
Phylogenetic relationships among the 19 taxa used in comparative genomics analyses.
Focal taxon, Hp, boxed in grey. We compared the Hp genome to the genome of the amphibian pathogen Bd and to a diverse group of other fungal genomes including representatives from all major fungal lineages. Phylogenetic relationship constrained at node between U. maydis and P. graminis and marked with an asterisk. Bayesian posterior probabilities are shown below internal nodes and ML bootstrap values from 100 replicates are shown above the nodes.

Chytrid growth on cane-toad-skin.
A. Negative control (no chytrid): intact skin after 14 days. B. Hp treatment: intact skin and no Hp growth after 14 days. C. Bd treatment: degraded skin and Bd growth after 14 days.

The enrichment of Cellular Component, Biological Process and Molecular Function GO terms of 417 Bd specific genes associated with a Pfam domain.
Figure 3.
Gene family copy numbers for metalloproteases (M36), serine-type proteases (S41), aspartyl proteases (ASP) and CRN-like proteins (CRN) in the Chytridiomycota (Bd, Hp and S. punctatus), and a Blastocladiomycota outgroup (A. macrogynus).
Phylogenetic relationship of taxa adapted from [8]. Focal taxa highlighted in grey.
Figure 4.
Maximum likelihood phylogenies of gene families containing (A) M36, (B) S41, and (C) Asp Pfam domains.
Each tip represents a single gene copy and each source species is denoted by shaded or hatched boxes (Bd: black, Hp: grey, S. punctatus: hatched, A. macrogynus: white). Bootstrap values over 80% indicated with asterisks at internal nodes.
Figure 5.
Left panel (paralog rates) shows box plots of synonymous substitution rates (Ks) for Bd lineage-specific duplicates in three protease families.
Right panel (ortholog rates) shows box plots of Ks values for putative orthologs between Bd and Hp, Bd and S. punctatus, and Bd and A. macrogynus. Box and whisker plots show median (line), inter-quartile range (box), 1.5 inter-quartile range (whiskers), and outliers (open circles).
