Research Interests

Cytokinins and their role in plant development.

I am using transgenic and mutant-isolating approaches for the elucidation of the role of cytokinins in the development of Arabidopsis thaliana . Transgenic Arabidopsis plants have been constructed which express the ipt -gene, which encodes the first step of cytokinin synthesis, after induction. Transgenic Arabidopsis plants have been constructed which constitutively express the ipt -gene. These plants show significant increases in biomass and strongly delayed flowering and senescence.
Several mutants have been isolated in Arabidopsis which show a significant increase in different cytokinin metabolites.

Differentiation and dedifferentiation processes in plant development.

I have isolated several mutant lines which show spontaneous formation of calli with different forms of differentiation which grow indefinitely in vitro . Some of these lines have significantly increased contents of cytokinins or auxins. Molecular characterization of these mutant lines is performed by Markus Frank in our laboratory.
