Botany – Genetics and Evolution of Plant Diversity
Prof. Dr. rer. nat. Sabine Zachgo, Direktorin des Botanischen Gartens
Our research team analyses key regulatory transcription factors that control plant development. To this end, we conduct comparative studies with the classical angiosperm model organism Arabidopsis thaliana and evolutionarily informative plant species. We currently use the liverwort Marchantia polymorpha and the amphibious liverwort Riccia fluitans to analyze the role of redox regulation in developmental processes and adaptation to terrestrial life.
Research topics
- Molecular developmental genetics of land plants
- Redox processes in cell division and differentiation
- Evolutionary adaptations of regulatory network activities
Model systems
- Arabidopsis thaliana, angiosperms with interesting novelties such as flower symmetry
- Marchantia polymorpha and Riccia fluitans
Methods
- Developmental genetics (genome editing, mutant analyses)
- Expression analyses (mRNA, protein)
- Transcriptomics (next generation sequencing)
- Morphological studies
- Fluorescence microscopy, redox sensors
- DNA/protein interactions (EMSAs
