We are probing plant life by developing simple and powerful tools and strategies to unravel plant signal transduction pathways extending from sensors/receptors to signaling cascades and target genes and proteins that are central to energy and metabolic homeostasis, innate immunity, stress adaptation, cell fate specification, plant shape and architecture determination. Our investigations are guided by our curiosity and the desire to promote the use of green plants as a versatile and fascinating model system for discovering fundamental principles in the regulatory networks of living organisms.
