Distribution of NRPS and PKS genes among Fusarium species based on BLASTn analysis of genome sequences. A gray box indicates that an apparently functional copy of the gene was present in the genome of species/strain indicated in the species tree to the left. A white box indicates that the gene was absent. A white box with the Greek letter Ψ indicates that only a pseudogene was detected in the genome. A black box indicates that an apparently functional gene was present in one or more strains of a species but was absent (or present as a pseudogene) in one or more other strains of the same species. Note that we analyzed multiple strains of only a small number of species; in addition to the two strains of F. oxysporum, FIESC 5 and FIESC 33 included in the species tree, we analyzed publicly available genomes of two or more strains of F. avenaceum, F. fujikuroi, F. graminearum, F. oxysporum, F. pseudograminearum and F. proliferatum. The species tree shown to the left is derived from (i.e., includes the same species and has the same topology) as the species tree in Fig. 1
