Phylogenetic and syntenic assays of PKS1 and PKS2 from <i>M</i>. <i>robertsii</i>, and their homologs in other ascomycete fungi.

<p>(<b>A</b>) Phylogenetic tree based on the amino acid sequences of the PKS KS domains. The Genbank accession number for each full-length amino acid sequence of each PKS is shown after the species name. The clade containing the <i>Metarhizium</i> PKS1s is highlighted in pink, that containing PKS2s is highlighted in red. Numbers at nodes represent the bootstrap values of Maximum Likelihood (left), Neighbor-Joining (middle), and the Bayesian posterior probabilities (right). A hyphen (-) indicates no support for the given node in the corresponding method. The scale bar corresponds to the estimated number of amino acid substitutions per site. (<b>B</b>) Schematic maps of the gene clusters containing <i>Pks1</i>, <i>Pks2</i>, or their homologs. Colors in the inset legend represent genes in the cluster; gray bars indicate genes that are not homologous to each other. The groups of fungal species that contain specific gene clusters are indicated with arrows.
