From: Glycoside hydrolases family 20 (GH20) represent putative virulence factors that are shared by animal pathogenic oomycetes, but are absent in phytopathogens

Maximum Likelihood (ML) phylogram inferred from eukaryotic Glycoside Hydrolase family 20 (GH20) amino acid sequences (443 characters). The tree is consistent with previously published GH20 phylogeny reconstructions, and shows that oomycete GH20 proteins (in bold, and circled in red) cluster in two distinct groups. The Saprolegnialean sequences appear as a strongly supported cluster nested within an arthropod-specific clade (animal clade 2, in blue). In contrast, the L. giganteum sequence appears as a sister taxon to a plant clade (plant clade 1, in green). All but one sequences were retrieved from animal pathogenic oomycete genomes, as GH20 were shown to be absent from plant pathogenic oomycetes. Numbers above the modes correspond to ML bootstrap values (1000 replicates). Numbers below the nodes correspond to Bayesian posterior probabilities (shown only when above 0.5). Asterisks indicate changes in topology between trees inferred from ML or Bayesian analyses. For clarity purposes, not all values representative of the support for nodes within each major clade are shown. The bar indicates the number of substitutions per site
