Colonization dynamics and grazing activity of ciliates in stream biofilms

Cross-barriers such as small dams cause local flow velocity heterogeneities, which might affect the formation, structure, and function of biofilms. The main objective of this thesis was to investigate the impact of flow velocity on colonization dynamics, grazing activity, and behavioral changes of...

Ezrin/F-Aktin und Signaltransduktion

Diese Arbeit beschäftigt sich mit der Rolle von ERM-Proteinen (Ezrin, Radixin, Moesin) in der Aktivierung von Ras. Ich zeige, dass siRNA abhängiges Blockieren von ERMs die von Rezeptor-Tyrosin-Kinasen (RTK) abhängige Ras-Aktivierung hemmt. Durch Immunopräzipitation zeige ich, dass ERM-Proteine in einem...

Regulation and evolution of the penicillin biosynthesis gene cluster of...

Penicillin is one of the most important antibiotics and consequently, its biosynthesis is probably the best understood pathway in fungal secondary metabolism. However, there is little knowledge about the environmental signals and their transmission modulating the expression of the structural genes. In...
