Zusammenfassung

Fusarium graminearum ist eines der weltweit gefährlichsten Getreidepathogene und eine Bedrohung für die Ernährungsgrundlage von Mensch und Tier. Insbesondere der Befall von Weizen führt zu Ertragsverlusten und Kontaminationen durch Mykotoxine. Deoxynivalenol ist ein gesundheitsgefährdendes Mykotoxin, welches die Biosynthese von Proteinen hemmt. Durch die Kombination von molekularbiologischen Methoden und hochauflösenden Mikroskopietechniken gelang es faszinierende Einblicke in die Pathobiologie dieses Getreideschädlings zu erhalten.

Abstract

Fusarium graminearum is one of the most destructive pathogens of cereals and a threat to food and feed production worldwide. Infection especially of wheat leads to yield losses and mycotoxin contamination. Deoxynivalenol is a hazardous mycotoxin inhibiting the biosynthesis of proteins. Its production by the fungus is a prerequisite for the colonization of the wheat spike. Combining molecular genetics with bioimaging techniques allows a fascinating insight into the pathobiology of this cereal pathogen.
