“…After 2 years of continuous cropping, the genes encoding key enzymes in the flavonoid biosynthetic pathway are upregulated in pea roots [90], increasing the synthesis of the enzymes and promoting the synthesis of flavonoids (Figure 5). Studies confirmed that flavonoids can activate antioxidant enzyme activities, enhance the antioxidant properties of low molecular weight antioxidants and indirectly scavenge ROS under adverse conditions [108,112]. At the same time, flavonoid compounds can provide H + to directly scavenge ROS, thereby reducing the damage of adversity to plants [108].…”

Legumes have important nutritional and economic values, but their production faces continuous cropping obstacles that seriously affect their yield formation. In order to reduce the negative impact of the continuous cropping obstacles of legumes, it is necessary to understand the response mechanisms of legumes to continuous cropping, the causes of continuous cropping obstacles and the measures to alleviate continuous cropping obstacles. This review aimed to identify the current knowledge gap in the field of continuous cropping obstacles of legumes and provide direction and focus for future research. The continuous cropping obstacles of legumes start with soil degradation, leading to oxidative stress in the plants. This triggers the expression of plant-hormone- and signal-molecule-related genes, activating the defense system and causing continuous cropping obstacles. Although there has been progress in researching these challenges in legume crops, many questions remain. We believe that the exploration of molecular mechanisms of legume crops responding to continuous cropping, rhizosphere signal exchange and soil environment repair mechanisms after long-term continuous cropping of soybean, and the excavation of candidate genes and functional loci related to continuous cropping obstacles in legume crops are breakthroughs for proposing effective continuous cropping obstacle management strategies in the future.

“…Тяжелые климатические условия и интенсивность нефтедобычи на территории исследования наложили особый отпечаток на развитие экосистем данного региона. Интенсивная нефтедобыча -в огромных объемах и масштабах, в тяжелых природно-климатических условиях, в течении более полувекового промежутка по времени, -характерная и специфичная особенность Среднеобской низменности в мировом масштабе [6,11,15,20,27,28,29,32].…”

Background. Two thirds of all oil reserves of the Russian Federation are concentrated on the territory of Western Siberia. Field work, production and distribution of petroleum products at the oil and gas field are the main reasons for the negative impact on the ecosystems of the northern territories. Purpose. The purpose of this study is to evaluate the chemical pollution dynamics of the rivers’ bottom sediments in the Middle Ob region, the region of the Samotlor field. Materials and methods. Based on the chemical analysis of the sediment samples, concentrations and total values of the following chemical elements were determined: manganese, copper, nickel, lead, chromium, zinc, iron sulfate ions, chloride ions, petroleum products, mercury. Based on the results of long-term studies of the chemical analysis dynamics of the bottom sediments in the Ob, Agan, and Vakh rivers, a correlation and regression analysis of the studied indicators was carried out. Results. The results of the correlation analysis suggest the existence of negative and positive correlations in the studied indicators. Regression analysis of the migration of chemical elements in sediment samples during the study period shows significant fluctuations in the total concentration of chemical elements in sediments, but there is a general tendency to decrease their concentration in sediments. Conclusion. Analyzing the ecological state of the studied rivers by the quality of bottom sediments, in general, we can conclude that they are in stable condition. During the study period, there has been a positive dynamics in the concentration of chemical elements in bottom sediments.

“…Механическое воздействие ведет к значительному нарушению окружающей среды: деформации поверхности и разрушению микрорельефа, подтоплению территорий и подпруживанию озер, полному или частичному удалению растительного покрова и торфа. Зона влияния данных нарушений достигает значительных расстояний, а в результате подтопления происходит смена существующих природно-территориальных комплексов, например, заболоченный лес сменяется болотом [8,33,[35][36][37][38][39][40][41][43][44][45].…”

Background. The study area is one of the main regions of the Russian Federation, where intensive development and production of hydrocarbons are carried out. They are directly accompanied by a very significant anthropogenic impact on the environment in general, and on water bodies in particular. The article, based on the analysis of chemicals concentration in surface waters, bottom sediments and coastland soil, gives an assessment of water bodies quality on the territory of the oil and gas industry. Purpose. The purpose of the study is to assess the quality of surface waters, benthic ecosystem and coastland soil of water bodies on the territory of oil and gas fields of the Middle Ob region. Materials and methods. On the basis of chemical analysis, concentrations of chemical elements were determined in samples of surface waters, bottom sediments and coastland soil of water bodies. Based on the concentration of chemical elements in a particular environment, the index of surface water pollution was determined by the calculation method, the state of the coastland soil and the benthic ecosystem was assessed. Results. The calculation of the integral assessment of water quality shows that the studied water bodies range from moderately polluted to extremely polluted. Quality deterioration of the benthic ecosystem is observed in most of the studied water bodies. Conclusion. The study of the environmental condition of water bodies by the quality of surface waters, bottom sediments and the coastland soil shows the negative anthropogenic impact of the oil and gas industry on the studied water bodies.
