Figure 1.

Phylogeny tree and structural variations of the FUB (Fusaric acid biosynthetic) gene clusters from Fusarium species. The phylogenetic tree was constructed based on the concatenated sequences of the 12 FUB gene coding sequences. All branches on the phylogenetic tree had 100 percent bootstrap support rate by maximum‐likelihood method and 100% posterior probability by Bayesian inference. The 12 FUB genes (denoted as FUB1 and 2–12 in the graph) are represented by green arrows. Structural variants with minor allelic frequency were denoted using bold lines in yellow (translocation), red (insertion > 50 bp) and blue (deletion > 50 bp).
