Research

Our roots go back to sixties of the last century, to Ivan Šetlík and his colleagues studying algal physiology and biotechnology in nearby Třeboň. Photosynthesis has been one of the key focuses because of its physiological, ecological and biotechnological importance. Also, multi-disciplinarity, novel methods and development of original instrumentation (PSI) have been the hallmarks of our research since the early days. Results from our department contributed to understanding of the physiological role of cytb559 in photoprotection, to understanding of the role of mycosporine-like amino acids in protection of algae against UV-B radiation, to constructing of numerous original instruments and methods and to identification of new, information-rich chlorophyll fluorescence transient in harmonically modulated irradiance. With support of the Academy of Sciences ČR, in collaboration with the University of S.Bohemia and with inspiration from Avigdor Scherz of Weizmann Institute of Science and Hugo Scheer of Ludwig Maxmillian University, we were the first pioneer lab starting research in Academic and University Center, Nové Hrady in 2000. We organized in Nové Hrady the first international meeting „Kinetic Fluorescence Imaging of Plants 2002“, laying foundations to the present AUC Conference Center. Ladislav Nedbal is, with Martin Trtílek, co-founder of Photon Systems Instruments, spol. s r.o. We designed and initiated Schola ludus project for undergraduate and graduate students in 2002. We were co-founders of Graduate College of Biophysics in Nove Hrady.
