The effect of a colloidal solution Cu,Zn-nanoparticles on pro-oxidative/antioxidative balance and content photosynthetic pigments leaf area winter wheat plants steppe (Acveduc) forest-steppe (Stolichna) ecotypes was investigated in drought conditions. It has been shown that decreased the negative action upon ecotype Acveduc. In particular, increased activity antioxidative enzymes reduced level accumulation thiobarbituric acid reactive substances (TBARS) stabilized relative water leaves....

The ability of seven species aquatic plants (Elodea canadensis, Najas guadelupensis, Vallisneria spiralis L., Riccia fluitans Limnobium laevigatum, Pistia stratiotes and Salvinia natans L.) to absorb metal nanoparticles from colloidal solutions was studied. It established that investigated have a high capacity for removal aqueous solution (30–100%) which indicates their phytoremediation potential. Analysis the water samples content elements including mixture (Mn, Cu, Zn, Ag + Ag2O) before...

Plants assimilate inorganic nitrogen (N) to glutamine. Glutamine is the most abundant amino acid in plant species, N-supplying precursor of all N-containing compounds cell and first organic molecule formed from taken up by roots. In addition its role nutrition, glutamine likely also has a function as signaling regulation metabolism. We investigated whether influences high-affinity transporter system for nitrate uptake. Therefore, we analyzed expression NRT2.4, which inducible N deficiency,...

Non-mycorrhizal but beneficial fungi often mitigate (a)biotic stress-related traits in host plants. The underlying molecular mechanisms are mostly still unknown, as the interaction between endophytic growth-promoting soil fungus Mortierella hyalina and Arabidopsis thaliana. Here, abiotic stress form of nitrogen (N) deficiency was used to investigate effects on colonized In particular, hypothesis investigated that fungal infection could influence N via an with high-affinity nitrate...

This paper presents research results on the sensitivity of buckwheat (Fagopyrum esculentum Moench.) inoculated with phosphate solubilizing microorganisms (PSM) to phosphorus deficiency using transformation major photosynthetic tissues membrane lipids as indicator. The analysis glyco- and phospholipids performed has revealed plants' ability react a deficit in selective accumulation sulfoquinovosyldiacylglycerol (SQDG) digalactosyldiacylglycerol (DGDG) along decrease phosphatidylglycerol (PG)....

Aim.To investigate structural and functional modifications of major components photosynthetic membranes endemic antarctic species D. antarctica under UV-B radiation.Methods.For quantitative determination membrane we used Arnon's method (for chlorophylls carotenoids); separation carotenoids was carried out by Merzlyak's method; polar lipids were isolated Zill Harmon in modification Yakovenko Mihno; glycolipids identification Yamamoto sulfoquinovosyl diacylglycerol content determined Kean...

The effects of water deficit modelling by polyethylene glycol (PEG), metal nanoparticles (NPs) and their combined action on status, chlorophyll fluorescence pigments composition in the leaves three drought tolerant wheat genotypes – Triticum aestivum L. (Trypilska Favorytka cultivars) dicoccum Schrank. (cv. Holikovska), have been studied. Water deficit, induced PEG, as well treatment with NPs (Cu, Fe, Mn, Zn) action, showed no maximal quantum yield PSII photochemistry (Fv/Fm) dark-adapted...

Field screening and phenotyping with biochemical parameters of winter wheat plants steppe ecotype treated exogenous hydrogen peroxide was carried out. The content TBARS, photosynthetic pigments sulphoquinovosyl diglyceride significantly different in leaves all varieties under normal conditions. increase TBARS hydroperoxides observed after the first foliar treatment by peroxide. After second we significant reduction them Shestopalivka variety. Exogenous iduced positive influence on formation...

Monitoring of A.V. Fomin Botanical Garden was performed by means UAV survey and satellite image data. Output products included a high-resolution visual map, map the normalized difference vegetation index (NDVI), digital elevation model (DEM), height thermal maps. These data were used to assess potential selected trees in mitigating "urban heat island" effect, particular, areas, height, volume photosenthetic potential. In such way we found most promising tree species terms recurring effect...

The possibility of using individual types woody plants in the collection A.V. Fomin Botanical Garden Taras Schevchcnko National University Kiev to overcoming "urban heat island" by content photosynthetic pigments and fluorescence induction parameters chlorophyll was studied. It has been established that leafy species families Sapindaceae (Acer rubrum, Acer velutinum) Magnoliaceae (Magnolia soulangeana. Magnolia kobus) are characterized a high "index viability".

The aim of the investigation was to study effect colloidal solution Cu2+ and Zn2+ nanoparticles on pro/antioxidant balance, content photosynthetic pigments (chlorophylls a, b carotenoids), chlorophyll a/b ratio morphometric parameters (relative leaf water content, area) winter wheat Triticum aestivum L. varieties Acveduc (steppe ecotype, resistant drought) Stolichna (forest-steppe sensitive under conditions simulated drought. drought created by stopping watering 8th day after emergence...

Deschampsia antarctica (endemic of Antarctic region) and caespitosa (inhabitant moderate climate regions) are two plant species Poaceae. The influences UV-B radiation H2O2 on photosynthetic apparatus these plants were studied. induced degradation chlorophyll a β-carotene in leaves both species. content galactolipids under conditions varied significantly, but comparatively stable sulfoquinovosyldiacylglycerol (SQDG) was observed. caused slight decrease QA pool oxidation level D. increase this...

The evaluation of the physiological condition winter wheat plants inoculated with phosphate mobilizing microorganisms under phosphorus deficiency conditions was performed. influence PaenibacilluspolymyxaKB,Rhizobiumradiobacter1333andRhizobium radiobacter 5006 on lipid-pigment complexes observed. accumulation major photosynthetic pigments, increasing chlorophyll (a+b)/carotenoids ratio and maintaining high level phosphatidyl glycerol stable content sulphoquinovosyl diacylglycerol revealed....
