Sabine Zachgo

Biography

Prof. Dr. Sabine Zachgo is a plant developmental geneticist. She was a group leader at the Max-Planck-Institute for Plant Breeding Research in Cologne and since 2007 she is a full professor of Botany at the University of Osnabrück (DE). Her lab applies a combination of genetic, morphological, biochemical and microscopic approaches to analyze key regulatory plant transcription factors and the impact of redox-processes on their regulatory activities. A broad range of informative plant species are studied to unravel molecular diversification mechanisms contributing to an increased developmental complexity and stress resistance throughout land plant evolution.

Talk title and synopsis

Evolution of plant cell proliferation control: Redox matters

TCP transcription factors are known key regulators of angiosperm cell proliferation processes. MpTCP1 from the liverwort Marchantia polymorpha promotes cell proliferation processes and the protein binds redox-dependently to DNA. Furthermore, MpTCP1 controls a comprehensive redox enzyme network, emphasizing the impact of redox-processes on developmental processes in bryophytes.
