| Key scientific achievements | My scientific activity is dedicated to the study of phosphoglycerate kinase, an important enzyme of the Calvin cycle, from the leaves of amaranth (Amaranthus cruentus L), a C4 plant, and the study of its physicochemical properties, as well as the physiological, biochemical, and agronomic characteristics of drought stress resistance of local varieties and introduced lines of wheat, a C3 plant. I have carried out my scientific research at the Department of Molecular Genetic Basis of Productivity Processes of the Institute of Botany of ANAS (currently Institute of Molecular Biology PLE Ministry of Science and Education of the Republic of Azerbaijan), Research Institute of Crop Husbandry Ministry of Agriculture of the Republic of Azerbaijan, Institute of Genetic Resources Ministry of Science and Education of the Republic of Azerbaijan, Institute of Plant Biology, Biological Research Center Hungarian Academy of Sciences. The main results obtained are as follows: 1. It was found that the Phosphoglycerate kinase enzyme is localized in the chloroplasts and cytoplasm of the mesophyll and bundle sheath cells of leaves of C4 plants. 2. There are 2 isoforms of the Phosphoglycerate kinase enzyme in amaranth leaves. The 1st isoform accounts for 88.5% of the total activity, and the 2nd isoform accounts for 11.5%.3. The molecular mass of the Phosphoglycerate kinase enzyme isolated and purified from amaranth leaves is 41 kDa.4. Mg2+ ions are essential for the activity of the Phosphoglycerate kinase enzyme. The Phosphoglycerate kinase enzyme shows nonlinear kinetics in relation to its substrates, 3-phosphoglycerate acid and MgATF2-. The Michaelis constants (Km) of the enzyme are 0.95 mM for phosphoglyceric acid and 0.33 mM for MgATP2-. High concentrations of MgATF2- inhibit the activity of the enzyme. SO42- ions inhibit the activity of the Phosphoglycerate kinase isolated from amaranth leaves.5. The dynamics of aboveground dry biomass of wheat genotypes were studied and genotypic diversity was revealed according to this trait. Before the heading phase, a larger dry biomass of the aboveground part was formed in the genotypes Garagylchig 2, Vugar, Tartar, Gyrmyzy bugda, Gobustan, Akinchi-84, Giymatli 2/17, Gyrmyzy gul 1, Tale 38, Ruzi 84 and Pirshahin 1. The greatest increase in dry biomass in a single plot was determined in the Gyrmyzy gul 1 genotype (42.7g m-2 day-1) and a positive regression relationship was revealed between the dry biomass of the aboveground part of the plant and productivity.6. Photosynthetic gas exchange indices (photosynthesis rate, stomatal conductance, intercellular CO2 concentration, transpiration rate) of wheat genotypes under irrigation and drought stress conditions in ontogenesis were studied and it was determined that these indices were higher in the heading-flowering phase. It was shown that the decrease in the rate of photosynthesis under drought stress occurs due to the decrease in stomatal conductance and mesophyll conductance, and in regulating the rate of photosynthesis, mesophyll conductance plays a superior role than stomatal conductance. The Tartar, Giymatli 2/17, Tale 38, 4thFEFWSNN50 genotypes are characterized by higher stomatal conductance, higher rates of photosynthesis and transpiration. A positive relationship was revealed between the rate of photosynthesis and the growth rate and productivity of the genotypes. It was determined that drought stress causes a greater decrease in photosynthetic gas exchange indices compared to salt stress.7. Drought stress causes a decrease in the amount of photosynthetic pigments (Chlorophyll a, b and carotenoids) and relative water content of leaves, and a greater decrease occurs in the genotypes Garagylchyq 2, Alinca 84, Tartar, Giymatli 2/17, Akinchi 84, Ruzi 84. A positive correlation was established between the amount of Chl (a+b) in leaves and relative water content.8. Adaptive changes in the distribution of the assimilation area and dry matter among various organs of the plant under water stress conditions were determined. It was shown that in response to water deficiency, leaf aging accelerates and the assimilation area decreases. The increase in the assimilation area of the stem continues until the grain formation phase, and the accumulation of dry matter continues until the milk ripening phase of the grain. The reduction in stem dry mass due to the transport of photoassimilates to the grain occurs less in the Gyrmyzy bugda, Dagdash and Saratovskaya 29 genotypes than in other genotypes, leading to a decrease in the yield index in these genotypes. In stressed plants, the transport of dry matter from the leaves, stem and vegetative parts of spike to the grain is accelerated.9. It was found that under drought stress conditions, the amount of proline involved in osmotic regulation in the cell increases. In response to water stress, the amount of proline increased by 4-6 times in the Garagylchyg-2, Tartar, Gyrmyzy gul 1, Tale 38 genotypes.10. It was found that the Sharg, Gyrmyzy bugda, Gobustan, Tale 38, 4thFEFWSNN50, Dagdash, Saratovskaya 29 genotypes have the ability to ensure that the plant temperature remains sufficiently lower than the ambient temperature through better regulation of gas exchange. 11. It was found that under drought stress conditions, the number of spikes per 1m2, the mass of spike, the mass of 1000 grains, biological yield are more sensitive to drought, while the plant height, the length and width of the spike, and the number of spikelets in the spike are relatively less sensitive yield components. Under drought stress conditions, grain yield and the number of spikes per 1m2, biological yield and yield index showed a positive correlation. Grain yield and yield components of durum wheat are more sensitive to drought stress compared to bread wheat. It was found that the genotypes Barakatli 95, Gyrmyzy gul 1, Tale 38 have higher potential yield. Genotypes that form stable yields under irrigation and drought stress conditions were identified.
