Phylogeny of PKS genes in FIESC. The condensed phylogenetic tree was generated by maximum likelihood analysis of the entire amino acid sequences of the coding regions predicted from 146 PKS enzymes identified in 13 FIESC genomes. All the homologous PKSs from Brown and Proctor 2016 were included in the analysis. The Gallus gallus fatty acid synthase (FAS) gene was used as outgroup. Clades corresponding to the three previously described major clades of reducing PKSs (R-PKS I, R-PKS II and R-PKS III) and the one major clade of non-reducing PKSs were resolved in this analysis with high levels of bootstrap support (in red type) and are delineated with horizontal lines
