Investigation of stability and dynamics of photosynthetic pigment - protein complexes using optical spectroscopy
ODERMATT, Mirjam
Isolated violaxanthin-chlorophyll a binding protein of Nannochloropsis oceanica was studied by optical spectroscopy, putting a specific focus on time-resolved fluorescence spectroscopy. Thereby, dynamic and kinetic information about the pigment-protein interactions with respect to non-photochemical quenching was collected utilizing pigment and intrinsic tryptophan fluorescence. Using this method, the investigation of the molecular environment of the pigment-protein complex during the process of qE was possible.
Efektivní velikost světlosběrných antén a její význam pro regulaci fotosyntézy
CHARVÁT, Filip
Nonphotochemical quenching and state transitions are an important photoprotective mechanism against excessive irradiation. In this work I studied changes in the size of the effective crosssection of photosystem II antennae in regard to the level of nonphotochemical quenching (state transitions) under different levels of light induced stress.
Application of fluorescent methods for studing light harvesting function of photosynthetical antenae in cyanobacteria
CHARVÁT, Filip
Measurement of variable chlorophyll fluorescence is an useful method for photosynthesis research. In this work, I have adjusted FRRF (Fast Repetition Rate Fluorescence) method for studing photoprotective mechanisms in cyanobacteria. I used FRRF for testing specific cyanobacteria mutants with changed phycobilisome composition.
