Impact of Microorganism Priming on Oxidative Processes and the Antioxidant Defense System of Grapes Infected with Downy Mildew
(Сибирский федеральный университет. Siberian Federal University, 2021-09)Priming plants with natural agents, including microorganisms, is a promising alternative to chemical methods of protection in growing plants and, particularly, in viticulture. However, the molecular mechanisms of the priming ... -
Some Aspects of the Relationship between Redox Metabolism and the Structure of Calciphytes
(Сибирский федеральный университет. Siberian Federal University, 2021-09)Calciphyte species form a systematically and structurally heterogeneous group of plants capable of tolerating highly stressful conditions. Various structural adaptations occur in calciphytes to protect them against excess ... -
High Temperatures Induce ROS Generation and Damage to Respiratory Activity in Saccharum officinarum Suspension Cells
(Сибирский федеральный университет. Siberian Federal University, 2021-09)High temperatures are important abiotic stressors affecting plant growth, development and productivity. One of the consequences of unfavourable temperature effects on plants is an increase in reactive oxygen species (ROS) ... -
Antioxidant Activity and Chemical Composition of Extracts from Fruiting Bodies of Xylotrophic Fungi Growing on Birch
(Сибирский федеральный университет. Siberian Federal University, 2021-09)The search for new natural sources of biologically active substances is a major issue in pharmaceutical industry. Xylotrophic basidiomycetes are common in forests worldwide, but as a prospective raw source of biologically ... -
Activity of Cell Wall-Bound and Cytosolic Peroxidases under the Aftereffect of Copper Ions in Nicotiana tabacum Plants
(Сибирский федеральный университет. Siberian Federal University, 2021-09)The adaptation of plants to an excess of heavy metals in the environment and their recovery after elimination of the stressor is of interest in connection with the large-scale pollution of ecosystems and their remediation. ... -
Redox Reactions in Hydrocharis morsus-ranae L. under Industrial Impacts
(Сибирский федеральный университет. Siberian Federal University, 2021-09)Aquatic ecosystems are very sensitive to industrial impacts, and, therefore, it is increasingly important to study the mechanisms underlying the tolerance of aquatic organisms to water pollution. Heavy metals (HMs) are ... -
Effect of Zinc Deficiency and Excess on the Antioxidant Enzymes Activity in Barley Seedling Leaves
(Сибирский федеральный университет. Siberian Federal University, 2021-09)Zinc (Zn) is an essential microelement in plant nutrition but its high concentrations can be toxic to plants. Either Zn deficiency or its excess negatively affects plant metabolism, in particular due to alterations in ... -
The Effect of Habitat Conditions on the Activity of Enzymes and Content of Metabolites of the Ascorbate-Glutathione Cycle in Plantago media Leaves
(Сибирский федеральный университет. Siberian Federal University, 2021-09)The ascorbate-glutathione cycle (AGC) is a metabolic pathway that detoxifies H2O2, which is a reactive oxygen species produced as a waste product in metabolism. The cycle involves the antioxidant metabolites – ascorbate, ... -
Foliar Content of Phenolic Compounds in Platanthera bifolia from Natural and Transformed Ecosystems at Different Stages of Orchid Development
(Сибирский федеральный университет. Siberian Federal University, 2021-09)The representatives of the family Orchidaceae Juss. are often used as a source of natural antioxidants, including phenolic compounds, which play an important role in plant resistance under stressful conditions. This study ... -
Comparative Evaluation of Prooxidant/Antioxidant Balance in Seed Progeny of Plantago major L. from Radioactively and Chemically Contaminated Areas
(Сибирский федеральный университет. Siberian Federal University, 2021)There are many studies addressing plant responses to radioactive and chemical contamination of soils, but few works have been devoted to comparison of biological effects in the areas affected by these human-induced factors. ... -
The Effect of UV-B Radiation on the Antioxidant System in the Peltigera aphthosa and Peltigera rufescens Lichens
(Сибирский федеральный университет. Siberian Federal University, 2021)Ultraviolet (UV) radiation is the short wavelength region of the solar spectrum. The high-energy photons of UV-B (280–315 nm) are potentially dangerous for all living organisms. The effect of UV-B radiation on lichens has ...
