Fluorescence of Photosystem I,ed PS I-RC has a structure with 90 antenna chlorophyll (Chi) . molecules surrounding the six core Chi . molecules that function in the fast electron transfer steps. The RC forms a system highly efficient for energy capture and charge separation. Measurements by the new confocal microfluorimetry tech

The Relationship between Photosynthetic Electron Transfer and its Regulation,er environmental stress. Thus, plants have evolved mechanisms for down-regulation which safely dissipate excess solar energy. The most important of these processes, the ones that lead to non-photochemical quenching (NPQ) of antenna excitons, are triggered by acidification of the lumen via ApH change

Analysis of the Chlorophyll a Fluorescence Transient,d by photosynthetic organisms under different conditions can be analyzed to provide detailed information about the structure, conformation and function of the photosynthetic apparatus and especially of photosystem (PS) II. The emphasis in this chapter is on the work done by R. J. Strasser and his co

Light Emission as a Probe of Charge Separation and Recombination in the Photosynthetic Apparatus: Rorescence during illumination or as delayed luminescence after illumination is turned off. Luminescence is measured in the form of delayed light emission (DLE) as a function of time or in the form of thermoluminescence (TL) as a function of temperature. Both fluorescence and luminescence originate m

In addition, there are reports of passive detection of chlorophyll fluorescence based on the FLD (Fraunhofer Line Discriminator) principle. Further, measurements of reflectance changes in the green part of the spectrum provides access to the efficiency of photosynthesis. In this chapter

Non-photochemical Energy Dissipation Determined by Chlorophyll Fluorescence Quenching: Characterizaphotosynthesis. In particular, analysis of Chi fluorescence quenching serves as a convenient, widely applied method to obtain complex information on the response of the photosynthetic apparatus in green plants to environmental factors. Whereas ‘photochemical quenching,’ qP, reflects the operation of
