Key Research Interests:
During evolution a vast diversity of plant forms have emerged. Enormous developmental plasticity of plants allows them to function in various environmental conditions, including situations when the entire plant is submerged in water. Plant morphogenesis is governed by molecular regulatory networks defining basic body plan. This can be compared to the rules used in Japanese garden design where particular elements mark boundary regions or define the space. This developmental plan, however, is further modified by environmental as well as internal factors, making it more like an English style sentimental landscape garden where strict division and pattern is not so obviously visible.
Plants are also subjected to the same physical laws that apply to buildings. There are numerous elements reinforcing or making the entire structure more plastic. Due to the composite nature of plant organs, understanding how basic information from molecular networks is transcribed into cellular effects (such as cell growth, division or expansion) and linking it with mechanical and biochemical feedbacks present during organ development is crucial for a proper and complete understanding of morphogenesis.
In my studies I try to build a holistic view of morphogenesis of plant organs where the study of cell division, cell growth and cell differentiation are the starting point for understanding developmental plasticity. I use integrative approach to study cellular changes during different aspects of plant organ development as well as evolution of developmental programs in context of the emergence of the new organ forms.
My main object of studies is leaf of higher plants, in particular I am interested in understanding how many different leaf forms evolved and what is the significance of this phenomenon.
Another subject of my work is developmental reprogramming during plant-pathogen interaction. I am interested in molecular, cellular and physiological aspects of pathogen and pest driven reprogramming of the host plant. So far my research in this subject is focused mainly on the clubroot disease caused by the Plasmodiophora brassicae. This obligatory pathogen of the Brassicaceae family species use very sophisticated mechanisms in order to exploit and modify plant endogenous regulatory pathways turning this way plants into factories producing and supplying food for the pathogen. As a consequence of infection reprograming of plant morphogenesis occurs and development of galls on the underground part of plants and disturbance in vascular tissue formation can be observed. Understanding the entire developmental reprogramming will help to design proper strategy for engineering tolerant plants, therefore this subject has not only biological but the applied aspect as well.
