Alle Organismen brauchen Energie, Pflanzen beziehen typischerweise ihre Energie aus dem Sonnenlicht: ohne Licht geht es nicht. Energie kann nicht aus dem Nichts entstehen. Es wird nicht möglich sein, dass Pflanzen ohne Energie leben; Wachstum geht nur dann ohne Licht, wenn Reservestoffe vorhanden sind, oder wenn Pflanzen-Teile (z.B. Wurzel oder Kartoffel) von anderen Bereichen (Blätter des Sprosses) versorgt werden.

In unserem Artikel wird gezeigt, dass man Pflanzen austricksen kann, dass man ihnen vorgaukeln kann, sie wären im Licht. Das ist wie wenn man ein weißes Bild sieht, obwohl man die Augen zu hat. Essen muss man trotzdem.

Principal research interests

My research interest is focused on a photoreceptor termed phytochrome. Many steps in plant development such as seed germination, flower induction, shade avoidance or de-etiolation are under phytochrome control. In my group we use bacterial phytochromes from e.g. Agrobacterium tumefaciens and Synechocystis PCC6803 as models for photoconversion. Upon light absorption phytochromes undergo typical spectral changes and protein conformational changes that trigger signal transduction. The molecular mechanisms behind these conformational changes are as yet unknown. We also use mosses, which stand at the base of land plant evolution, as models to study phytochrome action at the cellular level. With the help of mutants, we have identified specific phytochrome effects in these cells. In a future project it is planned to isolate microalgae for biomass production.

Projects

1. Biochemical studies on bacterial phytochromes, photoconversion
2. Agrobacterium tumefaciens light responses
3. Moss phototropism and other phytochrome responses, chromophore biosynthesis, microinjection
4. Screening algae for biomass production

Approaches

Recombinant protein expression, biochemical characterization, proteolysis, size exclusion chromatography, protein crosslinking, site directed mutagenesis, UV/vis spectroscopy, in vivo phytochrome measurements, protein crystallization, physiological assays, microinjection.
