Research directions of the laboratory:

• Structural and functional relationships in photosynthetic reaction centers of plants, algae and cyanobacteria.
• Effects of various stress factors on the photosynthetic apparatus of plants.
• Photosynthetic oxidation of water and oxygen release in the second photosystem (PSII).
• Energy production based on models of photosynthesis reactions.

Main scientific achievements:

• Electron transport Photosystem II was studied and it was found that the efficiency of the primary photoreaction in photosynthetic reaction centers depends on the redox state of plastoquinone. It was shown that the changing fluorescence of chlorophyll is the emission from the P680* molecule excited during the recombination of oxidized chlorophyll (P680+) and reduced pheophytin (Ph–) formed in the primary photoreaction in PSII. In the primary photochemical reaction, the energy barrier between P680+Ph– ion-radical pair and P680* levels formed in the reaction center of PSII was found to be 0.11-0.13 eV.
• During a two-electron reduction of the plastoquinone acceptor in PSII, a new component of chlorophyll sensitive to the effects of external magnetic fields in the micro- and milliseconds range of chlorophyll delayed light radiation, with an activation energy of 0.5-0.6 eV was revealed and its mechanism was clarified.
• Catalytic reactions in which water is photosynthetically oxidized were studied, and the mechanism of water oxidation was analyzed based on the dependence of the molecular reactions of the S-cycle of PSII on the pH of the environment.
• Together with tyrosine YD, Cyt b559 was shown to reduce the oxidized (S2 and S3) steps of the catalytic S-cycle of photosystem II by donating electrons.
