Title: The Effects of Water Stress on the Growth of Corn and the Activity Dynamics of NADP–Dependent Isocitrate Dehydrogenase Enzyme in the Leaf and Root T issues Authors: Aliyeva, Naila; Mamedov, Ziyeddin Abstract: Developmental dynamics of the NADP-dependent isocitrate dehydrogenase enzyme has been studied (NADP-ICDH, EC 1.1.1.42) as the reducing potential of the cell for the development of corn sprouts through water stress conditions (water shortage and over water stress) which has a great role in forming NADPH pool. It was determined that the activity of NADP-ICDH enzyme increases both in root and leaf tissues significantly for the effects of water stress and over water stress induces the activity of enzyme more sharply than water shortage stress. The activity degree of enzyme in all three variants manifests itself higher in leaf tissues than root tissues. It seems NADP is required for the corn seedlings in order to eliminate stress complications and NADP-ICDH enzyme is directly involved in its synthesis.

Title: Applicatıon of the Hydroponic Green Fodder Technology in Poultry Breedıng and Maintenance of The Broiler in as Provided by Zoogygienic Conditions Authors: Rusramova, Siala; Hasanov, Mirzammad Abstract: The article sets out as a goal the ensuring in a sustainable form of innovative development in the designing of feeding strategies within the framework of the project "Sustainable development of poultry farming and the creation of a value chain for food production" in farms of the republic. Also, for rational and proper feeding of birds, the use of the Hydroponic Green Fodder technology, the presence of high-calorie protein (raw protein) in the feed, as well as amino acids, a small amount of cellulose, carotene, calcium and phosphorus, create favorable conditions for the development of chickens.

Title: Investigation of SARS-Cov-2 Infection in Domestic Animals Authors: Jalladov, Qiyasaddin; Hajiyeva, Aytan; Mammadova, Sabina; Aliyeva, Chichak; Mammadova, Shabnam; Rustamli, Shumshad; Aliyeva, Kamala; Kangarli, Rana; Alizade, Fakhranda; Akhundova, Narmin Abstract: Concerned with the COVID-19 pandemic, the study of this disease in animals has got a great scientific importance in clarifying the information about the source and circulation of the infection. The study aimed to investigate the source of infection of domestic animals (dog, cat, cattle, sheep, goat and poultry) with SARS-CoV-2, as well as to identify susceptible animal species and ways of transmission of the virus. Observations were made on the animals selected for the study, from which nasopharyngeal and oropharyngeal smears were taken for PCR, and blood samples were taken for enzyme-linked immunosorbent assay (ELISA). The experimental part of the study was carried out in veterinary clinics, animal shelters and farms. Dogs and cats are kept in animal shelters and examined in veterinary clinics, as well as cattle, sheep, goats and poultry grown on various farms, were involved in the study. Antibodies to SARS-CoV-2 were detected in 11 of 645 samples taken from animals whose clinical signs of COVID-19 disease were initially observed or whose owners were exposed to the disease. Based on the results of the study, monitoring the dynamics of the spread of SARSCoV- 2 among animals is of great scientific and practical importance in preventing this process.

Title: Quantitative Trait Locus Mapping: Some Biological and Statistical Considerations Authors: Mohammadi, Seyyed Abolghasem; Ojaghi, Javid Abstract: Many important traits in plant and animal populations such as yield, quality, and resistance/tolerance to biotic and abiotic stresses are controlled by many genes with small effects and are known as quantitative traits (also ‘polygenic,’ ‘multifactorial’ or ‘complex’ traits). The regions within genomes that contain genes associated with variation of quantitative traits are known as quantitative trait loci (QTL). A key development in the field of complex trait analysis was the establishment of large collections of molecular/genetic markers, which could be used to construct detailed genetic maps of both experimental and domesticated species. These maps provided the foundation for the modern-day QUANTITATIVE TRAIT LOCUS (QTL) mapping methodologies. The identification of QTLs can help to understand how many genomic regions significantly contribute to the trait variation in a population and how much variation is due to additive, dominant or epistatic effects of QTLs. Although the basic principle of QTL mapping has been established in Sax’s work on beans, the identification of QTLs based only on conventional phenotypic evaluation is possible. A major breakthrough in the characterization of quantitative traits was initiated by the development of RFLP markers which created opportunities to select QTLs. After that generally, biparental populations are used to map QTLs, in which the marker genotype and trait phenotype data are analyzed to detect the association between the two. The advent of molecular marker technology and the development of detailed linkage maps in various organisms made it possible to dissect QTs into discrete genetic factors. This review focuses the discussion on the biological considerations and statistical methods used for mapping QTLs.
