Reactive oxygen species are generated during the processes of photosynthesis and nitrate reduction, which can compromise the integrity of biomolecules and membranes. During the vegetative phase of Fabaceae species, around half of translocated carbohydrate is used for nodule growth, while the other half returns to the aerial part with nitrogen incorporated. These sugars may be yet involved with membrane stabilization, signaling, and activation of important genetic pathways for plant development. Thus, the aim was to study the adjustments of the photosynthetic and antioxidant systems and the accumulation of carbohydrates and biomass in Glycine–Bradyrhizobium cultivated with nitrate (NO3−). Four treatments were evaluated in completely randomized blocks. Glycine–Bradyrhizobium was grown with 1.7 mM of NO3− (GB: 1.7 mM NO3−) and without NO3− (GB: 0 mM NO3−), and Glycine was grown with 1.7 mM of NO3− (G: 1.7 mM NO3−) and without NO3− (G: 0 mM NO3−). Glycine–Bradyrhizobium symbiosis contributes to photosynthetic metabolism and total sugars, reduces the action of antioxidant enzymes, and minimizes the use of nitrate in soybean cultivation.; Glycine–Bradyrhizobium with nitrate provided greater plant dry mass in the vegetative phase, along with increased enzymatic activity and reduced nodule mass.

Aim: to study the process of proteins transamination in syncytiotrophoblast of placenta villi of women who suffered the acute form of cytomegalovirus (CMV) infection during pregnancy.Methods: 30 pregnant women with CMV infection recurrence at the 25–28th week of pregnancy were examined. The activity of γ-glutamyltransferase in the peripheral blood of pregnant women was determined by spectrophotometry at the device «Stat-Fax-2100» (The USA). Hsp-70 and caspase-3 in placenta homogenate were found out with serological methods. The activity of glutamatdehydrogenase and pyridoxal-5-phosphatase was studied with histochemical method of Z. Loyd at the placenta slice of parturient women. The apoptotic changes in syncytiotrophoblast nuclei were defined by ISEL-method.Results. The peripheral blood of CMV-seropositive parturient women showed a reduction of γ-glutamyltransferase in 1.30 times. Histochemically we identified the reduction of reaction products' concentration in response to pyridoxal-5-phosphate by 2.14 times, to glutamatdehydrogenase by 1,57 times. At the same time there was an increase of caspase-3 in 2,8 times and reduction of Hsp70 in 2.6 times in placenta homogenate. The number of apoptotic changes in syncytiotrophoblast nuclei increased by 4 times.Conclusion. Worsening of CMV infection in the period 25–28 weeks of pregnancy leads to disruption of amino acid metabolism in the placenta, causing structural and functional and metabolic adjustment, and is one of the reasons for slow growth and lack of development of the fetus.

Soil salinity is one of the major abiotic stress factors that constrain plant growth and limit crop productivity. About a quarter of the global land area is affected by salinity; therefore, there is increased need to develop salt-tolerant crops. Tall fescue (Festuca arundinacea) is one of the most important cool-season turfgrasses, which has medium tolerance to salinity and has a promising potential to be used as a turfgrass under saline conditions. However, up to now, the maximum use of tall fescue under salinity stress is still limited by inadequate scientific literature. Recent studies have attempted to identify various adaptive responses to salinity stress at molecular, cellular, metabolic, and physiological levels in tall fescue. The successful integration of information concerning signal sensing, molecular tools with recent advances in -omics would certainly provide a clue for creating salt-tolerant tall fescue. Because salinity limits water availability to plants via hindering water absorption, and by inducing physiological drought, here we review and propose a probable mechanism of tall fescue response to salinity stress and to similar effects induced by drought based on published literature.

ABSTRACT Whole-genomic expression patterns were examined in Shewanella oneidensis cells exposed to elevated sodium chloride. Genes involved in Na+ extrusion and glutamate biosynthesis were significantly up-regulated, and the majority of chemotaxis/motility-related genes were significantly down-regulated. The data also suggested an important role for metabolic adjustment in salt stress adaptation in S. oneidensis.
