Abstract The ability to maintain the balance between absorbed light energy and used in photosynthesis is a key factor of plant adaptation variable environmental conditions. In this work, diurnal variations photosynthesis, respiration, thermal dissipation, activity antioxidant system were studied hoary plantain ( Plantago media L.) growing on an open slope (sun plants) under natural shading herbage (shade plants). highest leaves net photosynthetic rate (Pn) was observed early morning amounted...
Alternative oxidase (AOX) in the mitochondrial electron transport chain is considered important for sustaining photosynthesis under high light conditions. Here, we examined effects of AOX pathway on state chloroplast photoprotective systems. Arabidopsis thaliana plants (4 weeks old), comprising three genotypes (wild type [WT], overexpressing [XX-2] and antisense [AS-12] lines AOX1a), were exposed to moderately conditions (MHL, 400 μmol m-2 s-1) a short-term experiment (8 h). After 8 h MHL,...
Lichens are a stable, self-regulating association of fungus and algae or cyanobacteria. The composition photobionts is associated with certain taxonomic groups lichens. most common lichen green cyanoprokaryotes. Being well adapted, lichens play prominent role in the Antarctic flora. purpose work to study nitrogen-containing thalli samples were collected by doctor biological sciences M.P.Andreev (Komarov Botanical Institute Russian Academy Sciences) January–April 2015, 2016 2018 different...
Ultraviolet (UV) radiation is the short wavelength region of solar spectrum. The high-energy photons UV-B (280–315 nm) are potentially dangerous for all living organisms. effect on lichens has not been studied sufficiently. We conducted a comparative study effects long-term (10 d) exposure to environmentally realistic dose accumulation lipid peroxidation products (TBARS), H2O2 content, superoxide dismutase (SOD) activity, and respiration rate in Peltigera aphthosa from forest community...
The ascorbate-glutathione cycle (AGC) is a metabolic pathway that detoxifies H2O2, which reactive oxygen species produced as waste product in metabolism. involves the antioxidant metabolites – ascorbate, glutathione, and NADPH, well enzymes linking them. We studied effect of habitat conditions on activity contents Plantago media leaves. experimental plants grew floodplain meadow: sparsely vegetated coastal edge (Site 1) grass stand central part meadow 2). hoary plantain growing Site 1...
The seasonal and daily dynamics of the content nitrogen-containing compounds in leaves Hylotelephium triphyllum plants was studied. maximum total nitrogen, soluble protein free amino acids observed regrowth phase, followed by their reduction towards end growing season. characterized a high low morning hours. In H. , 23 2 amides were found. determined glutamine glutamic acid. 4 non-proteinogenic found: -aminobutyric, -alanine, ornithine, citrulline. proportion non-theeinogenic increased with...
In the field experiment on area of 100 m 2 impact weather conditions green mass formation and chemical composition early ripe three-line maizehybrid DorkaMGT grown in central agroclimatic region Komi Republic was studied. According tothe data three vegetation seasons (2018-2020), maize plants can form up to 56.5 t/ha northern non-black earth withthe sum average daily active temperatures over 10 °C (GDD ) about 1500 a hydrothermal coefficient (HTC) 2. The decrease GDD 30 % moderate...
