“…The existence of a sequence of changes in cell membranes under unfavourable conditions has been proved: phase transition of part of the lipids of membranes, disruption of the structure in the areas of interphase boundaries and increase of their permeability within defective areas (Veselov, 2002;Demidchik, 2015). The inhibition of membrane-bound enzymes, including transport ATPases, change in pH, activation of membrane phospholipases, and lipid peroxidase oxidation, have a direct effect on the increase in the exoosmosis of electrolytes (Hohenberger et al, 2011).…”

An important way of regulating the key units of metabolism in the plant organism under the action of stressors is the use of biologically active substances with regulating properties – plant growth regulators. They affect endogenous regulatory systems, altering key metabolic pathways and thus increasing the plant's sustainability and productive potential in adverse environmental conditions. The aim of the research was to establish the possibility of regulation of physiological processes in winter wheat varieties by exogenous treatment of plants with growth regulators of synthetic (salicylic acid) and natural (Emistim C and Biolan) origin to increase their resistance to the phytopathogen Erysiphe graminis DC f. sp. tritici Em. Marchal , the causative agent of powdery mildew. The intensity of the physiological processes in plants was evaluated by the dynamics of the activity of antioxidant enzymes – ascorbate peroxidase and catalase, the release of ethylene and the integrity of the cell membranes. The objects were selected varieties of soft winter wheat, which were grown in controlled growing conditions against the background of infection by powdery mildew. The treatment of plants was carried out using aqueous salicylic acid solutions in the concentration of 10–5 M (experimentally established by us), Emistim C and Biolan (manufacturer Agrobiotech) in the concentration specified by the manufacturer at the rate of 20 mL/ha, when the development of the disease reached 5% of the total natural background of the infection in the plants during the stages of heading-beginning of flowering. Infection of winter wheat with powdery mildew leads to disruption of cell membrane integrity, increased activity of catalase and ascorbate peroxidase in leaves of the susceptible winter wheat variety. The intensification of ethylene release by leaves of the resistant variety was observed, which was caused by the hypersensitive reaction of the hormone to the effect of stress. The use of plant treatment by growth regulators contributes to maintaining the integrity of membrane structures, adaptive changes in the activity of antioxidant enzymes and regulation of the synthesis of the stress hormone ethylene in both winter wheat varieties under stress. Such changes in the physiological processes induced by plant growth regulators are accompanied by the preservation of the grain productivity of winter wheat and the increase of their resistance to the development of the disease.

V-H ATPase and NaK ATPase are important classes of ATP-driven proton pumps that are present in the intracellular and plasma membranes of eukaryotic cells and play diverse roles in both normal and abnormal cellular processes. Among the subunits of the V-H ATPase complex, subunit a is a transmembrane glycoprotein that plays crucial roles in metabolism, growth, survival and cellular immunity. NaK ATPase subunit beta is thought to participate in the proper folding and movement of the NaK ATPase enzyme and may also aid cation transport. In this study, we analyzed the functions of V-H ATPase subunit a and NaK ATPase subunit beta from the Pacific white shrimp, Litopenaeus vannamei. Full-length cDNAs of the genes corresponding to V-H ATPase subunit a and NaK ATPase subunit beta were obtained, which were 2654 and 2055 bp long, with open reading frames encoding 830 and 313 amino acids, respectively. RT-PCR analysis indicated that mRNA transcripts were strongly (but differentially) expressed in the gills and hepatopancreas, and at lower levels in other shrimp tissues. In this study, for the first time, the gene expression of V-H ATPase subunit a and NaK ATPase beta of white shrimp Litopenaeus vannamei were analysed by quantitative real-time PCR after exposure to five kinds of environmental stresses (bacteria, pH, Cd, salinity and low temperature). The results demonstrate that both of the two genes are sensitive and involved in all different stress responses and are more sensitive to salinity than other stresses. And they may have relationship with the anti-stress mechanism induced by environment stress in shrimp.
