Overview
Welcome to my personal web site on plant biology research. My recent research topics at the Department of Plant Biology, University of Pécs are shown below. Scrolling down, you'll find links to my full publication list, including earlier work that was done at the Biological Research Center of the Hungarian Academy of Sciences and at various laboratories abroad. Since 2011, my research home is at the University of Pécs, the oldest university in Hungary, founded in 1367. At the Department of Plant Biology, we study acclimative plant responses to various environmental conditions.
Work on the effects of UV radiation is in collaboration with colleagues in Ireland, Sweden, and Germany in the framework of UV4Plants, the International Association for Plant UV Research.
Antioxidants and Pro-Oxidants
Plants continuously produce free radicals and other highly oxidizing molecules. Production rates are kept low by an array of safety mechanisms, such as the control of water status, lessening the amount of absorbed radiation, and dissipating surplus energy. Once produced, pro-oxidants are efficiently neutralized by a network of antioxidants. Using model plants, for example tobacco or Arabidopsis, and controlled environments in growth chambers, we study how this balance is altered by stress factors and how it is regained when plants are acclimated to the stress.
These model systems do not replicate outdoor conditions but allow us to focus on specific pathways and to set up working hypotheses.
Plants and Solar Radiation
Grapevine leaves are well adapted to sunlight, providing excellent material to study the special metabolites enabling them to tolerate UV radiation, high light intensities, high temperature, and other unfavorable conditions.
A collaboration between our department and the university's Research Institute for Viticulture and Oenology is aimed at connecting grapevine leaf physiology and metabolite content to environmental parameters. We study short-term responses over the day as well as long-term acclimation achieved during the whole lifetime of leaves. Here we have the opportunity to test how the antioxidant properties of individual compounds (for example of flavonoids) established in laboratory experiments are realized under field conditions.
These studies are supported by the Hungarian Scientific Grant Agency (grants OTKA K112309 and K124165).
