The capsid protein (СР) P41 is required for virion formation and facilitates long distance movement of the virus. Along with RNAi suppression, P19 protein is involved in the development of severe disease symptoms in N. benthamiana and elicitation of Hypersensitive Response (HR) in tobacco. Our results show that wild type TBSV infection of Solanum lycopersicum (cv. Money maker) triggers resistance to the virus. Despite detectable accumulation levels of P19 protein in leaf and root tissues, the infection was not accompanied with obvious disease symptoms. Contrastingly, inoculation with TBSV mutant, lacking capsid protein P41 demonstrated susceptibility to TBSV. Moreover, Chl-FI analysis of plants infected with virus exhibited significant changes in metabolism. Our data suggests that in response to CP expression tomato plants have evolved defense mechanisms to resist viral infection.","PeriodicalId":248021,"journal":{"name":"BULLETIN of the L.N.

Among the chemical factors that inhibit the self-cleaning ability of reservoirs, one can note an increased content of salt sulfates, chlorides, calcium, magnesium, zinc, and copper phenol. ammonium, nitrite nitrogen, total iron, and copper. An assessment of the self-cleaning capacity of water bodies in the Akmola region was given based on oxygen indicators: the amount of dissolved oxygen in the water and the biological oxygen demand (BOD5). Rivers and lakes, based on the results obtained, were divided into six classes of self-cleaning ability, and a graph was also built from which among the studied water bodies, according to general annual indicators, lakes with low self-cleaning ability prevail. It has been established that the self-purification potential of waters can be influenced by both the excess of the content of individual hydrochemical components and the amount of the exceeded components, which can have a synergistic effect. Along with this, we studied which of the accompanying hydrochemical components affect the purification potential of water in lakes and rivers.","PeriodicalId":248021,"journal":{"name":"BULLETIN of the L.N.

The article provides information on the use of lactic acid bacteria in the production of fermented milk products (drinks) for prophylactic purposes. The important antimicrobial and biological properties of lactic acid bacteria are presented, according to which active strains of lactobacilli are selected and identified during screening, which are promising as ferments for obtaining bioproducts (drinks) of probiotic value. From literary sources, the article presents the high efficiency and safety of the use of probiotic lactic acid bacteria in use as ferments to produce fermented milk bioproducts with high antagonistic activity, high bacteriocin-producing activity, high adhesive activity, flavoring properties, and synthesis of vitamins. Thus, studies on the creation of fermented milk products with a specific composition and properties will give the product therapeutic and prophylactic properties due to the inclusion of probiotic strains in their composition. The development and creation of new domestic starter cultures in Kazakhstan is an urgent area based on strains of lactic acid bacteria isolated mainly from natural local national fermented milk products, as well as the development of combined therapeutic and prophylactic products (drinks) with the use of probiotics and vitamin-mineral substances.

The article presents data on the dynamics of the annual precipitation and temperature regime of the Kerbulak district of the Almaty region for 2010-2020. Based on these climatic conditions, there was determined nature of their impact on the vegetation cover of pastures. The article identifies desert and semi-desert plant communities that form a natural food base for farm animals. Based on the data provided by the Committee for National Statistics on the number of livestock, the article describes dynamics of the number of livestock over the past 10 years. The article establishes main directions of the development of animal husbandry in this region. Results of the research made it possible to determine the possible causes leading to the processes of desertification and violations of the ecological state in the pastures of the Kerbulak region.","PeriodicalId":248021,"journal":{"name":"BULLETIN of the L.N.

World agriculture is constantly under an influence of various biotic and abiotic factors that limit productivity of agricultural crops. Pathogens, including fungi, bacteria, viruses, insects and parasitic plants, are severe biotic stresses that can cause severe crop losses. Molecular interactions between a virus and a plant are one of the main models in the understanding of antiviral defense systems and plant interference. The article discusses main classes of resistance genes, RNA interference and RNA-mediated adaptive immune system of bacteria and archaea - CRISPR/Cas. Recent studies indicate that the CRISPR/Cas system may play a significant role in conferring antiviral resistance to plants.

Starch and protein are among the main components of grains. In addition, it contains vitamins, minerals and fats. The criteria for high quality rice vary from country to country. For example, in the Philippines, Bangladesh and India, a preference is given to rice with a high amylose content. In Japan, Egypt and Korea, a preference is given to low-amylose varieties. All varieties are used in China, Myanmar, Nepal and Malaysia. Starch is a major contributor to the culinary and nutritional quality of rice. In cereal grains, starch consists of C6 sugar, which is polymerized into endosperm starch granules. There are two types of polymerization: straight-chain amylose and amylopectin with branched-chain sugar molecules that are linked by glycosidic bonds. The light-optical properties of the caryopsis depend on the type of starch polymerization. In caryopses that contain 20-30% amylose, the endosperm is transparent, and with waxy starches, it is cloudy. According to the composition of starch, grains are divided into glutinous and non-glutinous. However, there are many intermediate forms. One of the important indicators and a good indicator for assessing the quality of grain is the content of amylose. The culinary advantages of rice cereals (coefficient of water absorption and weld, taste and consistency of porridge) depend on the content of amylose. In Kazakhstan, targeted studies have not been carried out to determine the quantitative content of amylose in rice genotypes with a colored pericarp. Therefore, the authors undertook biochemical screening for amylose content in rice genotypes with a stained pericarp and their parental forms. The article presents results of biochemical analysis of generations F6-F7 hybrids with stained pericarp for amylose content. As a result of the study, it was revealed that among the studied rice samples there are no high amylose genotypes, and the amylose content ranges from 0 to 24.5%. In terms of amylose content, the studied rice genotypes were classified into 4 groups.","PeriodicalId":248021,"journal":{"name":"BULLETIN of the L.N. Gumilyov Eurasian National University.
