Abstract A comparative study of the allele pool and the genetic structure of two Russian and one Belarusian populations of the wisent Bison bonasus against the representatives of the species of Bison bison and the genus Bos taurus was carried out. Russian populations were represented by samples of the Oka State Natural Biosphere Reserve (n = 42) and the Prioksko-Terrasny Nature Biosphere Reserve (n

Abstract The Mi gene is known to involve in the resistance response to some Root knot nematodes, Meloidogyne spp. in tomato plants Lycopersicon esculentum. Root knot nematodes cause significant damages to almost all crops in the world. Among Meloidogyne species, Meloidogyne incognita is one of the most damages species causing a vast amount of crop loss including tomato plants. The resistance gene may

Abstract The JIN1/MYC2 transcription factor, which is currently considered to be the key in jasmonate signaling, is also involved in the transduction of abscisic acid signals and, probably, in the effects of other intermediaries involved in the formation of plants’ adaptive responses. Arabidopsisjin1 mutants were used to study its possible involvement in protective effects of hydrogen sulfide (H2S)

Abstract The objective of the investigation was to study variation of storage proteins in two Crimean populations of Dasypyrum villosum from Beregove of the Bakhchisarai region and from the Tauric Chersonese National Reserve (Sevastopol). Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis of seed storage proteins was performed to analyze diversity of high-molecular-weight glutenin subunits

Abstract This paper considers current views on the classical determinants of Helicobacter pylori virulence, pathogenetic effects of phosphorylation, and the process of CagA translocation into gastric mucosa (GM) cells and characterizes surface membrane receptors of VacA binding to epithelial cells of the gastric mucosa. The necessity of genetic typing of Helicobacter pylori to determine the potential

Abstract Satellite DNA is the main component of functional centromeres and forms the main structural constituent of heterochromatin. The presence of alkali-labile sites (ALSs) is a feature inherent to chromatin structure. Here we aimed to characterize ALSs in different satellite DNA loci in cervical epithelial cells using DNA breakage detection coupled with fluorescence in situ hybridization (DBD–FISH)

Abstract The review is devoted to the analysis of the current achievements of Corynebacterium glutamicum metabolic engineering for the production of lysine. Key genes of lysine biosynthesis in C. glutamicum and ways of creating new genetically modified strains are considered. The role of different plasmids, vector cassettes, and promoter types for the regulation of gene expression in C. glutamicum

Abstract Using the Comet assay, the peculiarities of the interaction between malignant and normal human peripheral blood lymphocytes under cocultivation and separate cultivation were investigated. A decrease in Tail Moment was observed against an increase in the frequency of cells in the state of apoptosis in the culture of lymphocytes from conditionally healthy volunteers (bystander cells) under the

Abstract Proximal spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disease caused by homozygous deletion in the seventh exon of the SMN1 gene. The aim of this work is to analyze the association of the allelic polymorphism of telomeric genes SMN1 and NAIP and the centromeric gene SMN2 of the 5q13 region with the clinical phenotype of SMA. It was shown that the homozygous genotype

Abstract India currently has the second largest number of individuals suffering from diabetes across the world. Hence, it is pertinent to explore the genetic variations in Indian populations to comprehend the extent of genetic heterogeneity. We studied the association of gene variations of four candidate genes [SLC30A8 (rs11558471), CDKAL1 (rs94655871), TCF7L2 (rs12255372) and HHEX (rs1111875)] with

Abstract Routine, GTG-, and Ag-staining techniques for the metaphase chromosome analysis were used to determine the spontaneous frequency of chromosomal aberrations and the level of chromosomal variability in the blood lymphocytes of Ukrainian buffaloes (Bubalus bubalis L.). It has been established that the diploid complement of chromosomes within the studied population of animals consists of 50 chromosomes

Abstract The formation of bean seeds in plants systemically infected with bean common mosaic virus is accompanied by the intense deposition of callose and lignin in zones of nucellar, integumental, and micropillar tissue barriers, thus preventing the viral spread. At a high concentration of viral particles in plants, the ovule tissue degrades with the development of the typical hypersensitivity response

Abstract An allozyme analysis of five sets of polymorphic loci of the gynogenetic Prussian carp C. gibelio from Northern Ukraine made it possible to identify within this species 29 genetic forms of clonal and recombinant nature, which can be divided into two categories. The first one is represented by the clonal C. gibelio-1 biotype with the modal number of 156 chromosomes and several unique alleles

Abstract The content of indole-3-acetic (IAA), gibberellic (GA3), abscisic acids (ABA), and cytokinins—zeatin (Z), zeatin glucoside (ZG), zeatin riboside (ZP), isopentenyladenin (iР), and isopentenyladenosine (iРА)—was determined using the method of high-performance liquid chromatography in fern Polystichum aculeatum gametophytes at different stages of morphogenesis in vitro culture. It was shown that

Abstract Rye (Secale L.) is a member of family Poaceae (tribe Triticeae) and includes perennial or annual, self-incompatible or self-compatible, and cultivated, weedy or wild species. Classification of the genus Secale is inconsistent, and comprises 3–4 to 8 species from the phylogenetic studies in the last ten years. Progress in rye breeding has been significantly reduced due to involving a small

Abstract MicroRNAs (miRNAs) are highly conserved, non-coding, 20–24 nucleotides long RNA molecules that play important regulatory roles in plants and animals. Due to several limitations involved in the experimental validation of potent miRNAs, in silico prediction of miRNAs and their target(s) from various organisms have been successfully employed. Cranberries are one of the healthiest fruits due to

Abstract The degree of intraspecific genetic polymorphism and heterozygosity, the germinal death, viability of seeds, and the cytogenetic state of vegetative Ulmus pumila and U. suberosa meristems were analyzed for determining the mechanisms of plant population invasiveness in the steppe Dnieper region under climate changes. The studied U. pumila population were different in terms of germinal (embryonic)

Abstract— Hydrogen peroxide, one of the main factors of Mycoplasma pneumoniae pathogenicity, is released in the reaction catalyzed by glycerol-3-phosphate (G3P) oxidase enzyme (EC 1.1.3.21). During the study, nucleotide substitutions in the glycerol-3-phosphate oxidase gene of Mycoplasma pneumoniae clinical isolates, the presence of which was accompanied by different levels of hydrogen peroxide production

Abstract This paper presents results of studying the genetic diversity of 126 sunflower inbred lines from the collection fund of the Experimental Farm of Oilseeds of Kazakhstan for protein and SSR markers. The polymorphism of collections in terms of the composition of helianthinin, seed storage protein, was not high. In the zone of fast-moving proteins, three variants of components were found that

Abstract Gene targeting is extensively used to generate designer mouse mutants and to study gene function in vivo. Knockout mice that harbor a null allele in their germline provide appropriate genetic models of inherited diseases and often exhibit embryonic or early postnatal lethality. To study gene function in adult mice and in selected cell types, a refined strategy for conditional gene inactivation

Availability of an efficient transfection protocol is the first determinant in success of gene transferring studies in mammalian cells which is accomplished experimentally for every single cell type. Herein, we provide data of a comparative study on optimization of transfection condition by electroporation and chemical methods for Huh-7 and Vero cells. Different cell confluencies, DNA/reagent ratios

Phenomenon of RNA-induced gene silencing is a highly conservative mechanism among eukaryotic organisms. Several classes of small RNAs (siRNAs and miRNAs) 21-25 nt in length, which play a significant role in the processes of development of an organism, occurred important components of antiviral defence in animals and plants. This review shortly describes the main stages of gene silencing mechanism,
