Conservation of key secondary metabolite biosynthesis genes in the Leptosphaeria maculans -L. biglobosa evolutionary series. (A) Non-ribosomal peptide synthases (NPS); (B) Polyketide synthase (PKS) genes. The colour of shading indicates those genes present (dark shading) or absent (white) in the corresponding species. The phylogenetic tree on the left is a simplified version of that in Figure 1, and the calculated divergence times (in MYA) are indicated.
