Pyrrocidine, a molecular off switch for fumonisin biosynthesis
Fig 5
FvZBD1 is adjacent to the well-characterized FUM cluster.
Genes are represented by colored arrows with labels. The direction of arrows denotes the orientation of genes. A zoom-in section of the FvZBD1 locus indicates the deletion occurs at 646 bp downstream of FvZNF1 and 999 bp upstream of FUM21 when generating ΔFvZBD1 mutants. FvZBD1 is replaced with the hygromycin resistance cassette (HRC).
