Title: Structural reorganization of the fungal endoplasmic reticulum upon induction of mycotoxin biosynthesis

Eukaryotic cells routinely compartmentalize metabolic pathways to particular organelles for biosynthetic purposes. Relatively few studies have addressed the cellular localization of pathways for secondary metabolites synthesis. In this study, the phytopathogenic fungus Fusarium graminearum reorganized its endoplasmic reticulum (ER) when triggered to produce mycotoxins, both in vitro and in planta. Fluorescence tagged biosynthetic proteins were found to co-localize with the modified ER as confirmed by co-fluorescence and co-purification with known ER proteins. Microscopy, cell sorting, and proteomics were applied in this FICUS collaborative effort.
