Urban soil organic carbon and its spatial heterogeneity in comparison with natural and agricultural areas in the Moscow region.

Abstract: Soils hold the largest carbon stock in terrestrial ecosystems. Soil organic carbon (SOC) is formed under a combination of bioclimatic and land-use conditions. Therefore, one would expect changes in SOC stocks with land use changes like urbanization. So far, the majority of regional studies on SOC stocks exclude urban areas. The urban environment has a unique set of specific features and processes (e.g., soil sealing, functional zoning, settlement history) that influence SOC stocks and its spatial variability. This study aims to improve our understanding of urban SOC in comparison with agricultural and natural areas for the Moscow region (Russia). SOC content was studied in different land use types, soils, and urban zones through stratified random sampling. Samples of topsoil (0–10 cm) and subsoil (10–150 cm) were taken at 155 locations. SOC contents were significantly higher in urban areas compared with non-urban areas (3.3 over 2.7%). Further analyses proved that the difference can be explained by the so-called “cultural layer”, which is the result of human residential activity and settlement history. SOC contents in the urban environment presented a very high spatial heterogeneity with standard deviations of urban SOC considerably higher than those for agricultural and natural areas. Soil depth, soil type and land-use factors had a significant influence on SOC variability determining more than 30% of the total variance. SOC contents in urban topsoil were mostly determined by soil type. In natural and agricultural areas soil type and land-use determined SOC contents. The results confirm the unique character of urban SOC and the need to reconsider established scientific and management views on regional SOC assessment, taking into account the role of urban carbon stocks.

The long and winding road leading to the successful introgression of downy mildew resistance into onion

Abstract: Downy mildew resistance originating from Allium roylei Stearn provides a complete resistance to onions and is based on one, dominant gene. Since A. roylei can successfully be hybridized with onion (A. cepa L.), a breeding scheme aimed at the introgression of this gene was initiated ca. 20 years ago. Several setbacks in this programme were encountered, firstly the identified molecular marker linked to the downy mildew resistance locus became increasingly difficult to use and finally lost its discriminating power and secondly the final step, making homozygous introgression lines (ILs), turned out to be more difficult then was hoped. GISH analysis showed that the chromosomal region harbouring the resistance locus was the only remaining piece of A. roylei in the nuclear background of onion and it also confirmed that this region was located on the distal end of chromosome 3. It was hypothesized that some factor present in the remaining A. roylei region was lethal when homozygously present in an onion genetic background. The identification of an individual with a smaller and more distally located introgression fragment and homozygous ILs in its progeny validated this hypothesis. With the help of these nearly isogenic lines four AFLP® markers closely linked to the resistance gene were identified, which can be used for marker-aided selection. The introduction of downy mildew resistance caused by Peronospora destructor into onion is a significant step forward in the development of environmentally-friendly onion cultivars.

Comparative Analysis of Formation of Industry 4.0 in Developed and Developing Countries

Abstract: The purpose of the article is to perform comparative analysis of formation of Industry 4.0 in developed and developing countries. As peculiarities of formation of Industry 4.0 in developed countries have been studied in this book in the process of studying successful experience of formation of Industry 4.0 in the countries of the world, the authors focus on determining the specifics of formation of Industry 4.0 in developing countries. In order to ensure compatibility of data for developed and developing countries, the similar methods are used—which are based on the authors’ methodological recommendations for monitoring the process of formation of Industry 4.0 in developing countries in 2017 and evaluating effectiveness of Industry 4.0 from the point of view of stimulation of development of knowledge economy in developing countries. During comparison of results of research of the essence and peculiarities of formation of Industry 4.0 in developed and developing countries, the method of comparative analysis is used. For determining the barriers on the path of formation of Industry 4.0 in developing countries, the authors use the method of systemic and problem analysis. For complex study of specifics of formation of Industry 4.0 in developing countries, the objects are the countries that are peculiar for various levels of socio-economic development and belonging to various geographical regions of the world: the South African Republic, China, India, and Brazil. As a result of the research, it is substantiated that the process of formation of Industry 4.0 in developing countries has its peculiarities and is different than in developed countries. As compared to developed countries, in which the process of formation of Industry 4.0 was started earlier and aimed at marketing and social results, developing countries face institutional (absence of state policy of formation of Industry 4.0) and financial barriers and seek economic goals. At the same time, the initiative approach to formation of Industry 4.0 in developing countries, within which the initiators of this process are economic subjects (companies), envisages larger flexibility and effectiveness as compared to the directive approach (state initiative), which is applied in developed countries.
