Frank Wellmer Short CV 1998 Ph.D. University of Freiburg (Germany) 1999-2005 Postdoctoral Fellow, California Institute of Technology (USA) 2005-2006 Senior Research Fellow, California Institute of Technology (USA) 2006-2012 Assistant Professor, Trinity College Dublin Since 2012 Associate Professor, Trinity College Dublin Research In our laboratory, we are trying to answer fundamental questions in developmental biology: how are complex organs formed from small sets of undifferentiated precursor cells and what are the genes and molecular mechanims that contribute to the regulation of development? We are especially interested in understanding the architecture and composition of the gene regulatory networks underlying flower formation in the model plant Arabidopsis thaliana. Flower development is an excellent system for studying the molecular mechanisms underlying organogenesis in plants. Extensive genetic analyses have led to the identification of several key regulatory genes of this important biological process. Most of these genes encode transcription factors or other proteins involved in the regulation of transcription, indicating the existence of a complex gene regulatory network that underlies flower development. However, the target genes of these transcriptional regulators, the cis-regulatory elements to which they bind, and their regulatory interactions are still largely unknown. What is more, the vast majority of the known floral regulators act during very early stages of flower development, before floral organs are initiated, and comparatively few genes controlling organ differentiation have been identified so far. Thus, new experimental approaches are needed to obtain a comprehensive view of the developmental mechanisms that control flower formation.
