Research paper thumbnail of The Size of the LightHarvesting Antenna of Higher Plant Photosystem II Is Regulated by Illumination Intensity through Transcription of Antenna Protein Genes

We implement an improved method for the measurement of hydrogen peroxide (H 2 O 2 ) production in lipid phase of photosynthetic membranes of chloroplasts. Total rate of H 2 O 2 production and the production within the thylakoid membrane under operation of photosynthetic electron transport chain is evaluated. Obtained data show that even in the presence of an efficient electron acceptor, methyl viologen, an increase in light intensity leads to an increase in H 2 O 2 production mainly within the thylakoid membranes. The role of H 2 O 2 produced within the photosynthetic biological membrane is discussed.
