| Basic scientific achievements | The research covers the structural-functional relationship in the photosynthetic reaction centers of plants, green algae and cyanobacteria, the mechanism of photosynthetic decomposition of water and molecular oxygen evolution in photosystem II (PSII), biomimetic PSII and artificial photosynthesis, and molecular mechanisms of plant stress. Scientific researches were conducted in Azerbaijan Research Institute of Crop Husbandry, Institute of Photosynthesis and Soil Science of USSR Academy of Sciences, Institute of Botany, ANAS, Lund University of Sweden, Kwansei Gakuin University of Japan and Photodynamics Research Center- RIKEN of Japan. The following results were obtained: 1. Electron transport was studied in the second photosystem and it was found that the efficiency of the primary photochemical reaction and electron transport in photosynthetic reaction centers (RC) is higher in the two-electron reduced state of plastoquinone than in the single-electron reduced state.
2. The recombination of oxidized chlorophyll P680+ and reduced pheophyte Ph– formed in the reaction center of PS2 during the initial photoreaction has been shown to be luminescence (recombination luminescence) from an excited chlorophyll molecule (P680 *). 3. The energy barrier between the energy level of the ion-radical pair [P680 + Ph–] formed at the reaction center of PSII as a result of the initial photochemical reaction and the singlet excitation level of chlorophyll (P680 *) was found to be 0.11-0.13 eV. 4. 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 it was shown that this radiation was caused by the emission of a light quantum of during the return of the excited triplet (TP680) level of the chlorophyll molecule to the base level by successively passing through the triplet and singlet states of RC. 5. The role of bicarbonate ions was studied in PSII and it was found that the main site of the bicarbonate action was its electronic acceptor side. It was shown that bicarbonate is necessary for the regulation of electron transport between the electronic acceptors QA and QB of PSII, and it can also be involved in the regulation of catalytic reactions in PSII leading to the oxidation of water and the evolution of oxygen.
6. According to the experimental and theoretical data, oxidation of water by PSII is based on a metal-radical mechanism, which involves the participation of Mn-cluster, tyrosine YZ radical (YZ•), D1-His190 and other amino acids in the hydrogen bond with tyrosine. Transport of a proton and electron from a water molecule in contact with an Mn cluster to a tyrosine (YZ •) which trasferrerd proton to lumen by D1-His190. 7. In Ca2+ lacking PSII, the function of S-cycle in S2-S3 was restored at acidic pH values. Thus, Ca2+-+ -factor was shown to play an important role in regulating proton balance and proton flow as a component of the catalytic site where water is oxidized. 8. It has been shown that under physiological conditions, the pH of the lumen medium can control the electron transport at the catalytic site where water is oxidized by influencing the course of certain reactions (found in some transitions of the S-cycle). This, in turn, protects the secondary photosystem from damage by limiting the electron transport during the over-saturation of the reactions at the reaction center.
9. It was shown that together with tyrosine YD, Cyt b559 reduces electrons by giving electrons to the oxidized (S2 and S3) stages of the catalytic S-cycle of photosystem II. While the reduction of stage S3 is based on the competition between tyrosine YD and Cyt b559 determined by the redox state of the former, in the reduction of S2 stage, Cyt b559 is the dominant electron donor and participates in both direct and P680, YD, YZ and Car/D2-ChlZ-mediated electron transfer. In turn, this allows Cyt b559 to participate in the regulation of processes such as electron deficiency (or excess) in PSII under extreme conditions. 10. It has been found that it is possible to restore electron transport under light in a second photosystem inhibited by the effects of thermal stress at high temperatures.
