Research ArticleOpen accessIn the author namesSSR Analysis of Nuclear DNA of Annual and Perennial Sunflower Species (Helianthus L.)N.V. Markin, A.V. Usatov, A.V. Grinko et al.Genotyping of 29 species of genus Helianthus L., including 5 annual and 24 perennial species from the collection of the N. I. Vavilov All-Russian Institute of Plant Genetic Resources has occurred, for this purpose were selected 52 SSR markers, with localization on all the 17 linkage groups of the sunflower genome. All the studied sunflower samples had unique SSR loci … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 25 Apr 2020 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the author namesSSR Analysis of the Chloroplast and Mitochondrial Genomes of Cultivar Lines and Wild Types of the Sunflower (Helianthus L.)Vladimir Arturovich Khachumov, Alexander Vyacheslavovich Usatov, Kirill Vitalievich Azarin et al.SSR analysis of chloroplast and mitochondrial genomes of cultivar lines and wild species of sunflower (Helianthus L.) were completed. The polymorphism of 18 microsatellite loci of the chloroplast and mitochondrial genomes was investigated. Based on the obtained data was constructed dendrogram showing the genetic diversity of chloroplast and mitochondrial genomes of sunflowers. The studied species were clustered into annual and … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 19 Feb 2020 · 7,675 accessesView PDFCite
Research ArticleOpen accessIn the author namesProducts of Solid-Phase Probiotic Bacilli Fermentation Increase Food Conversion Efficiency and Stimulate Chicken GrowthMazanko Maria S., Aleksandr I. Klimenko, Ivan F. Gorlov et al.Poultry farming is one of the major directions in agriculture. Agricultural poultry has high growth speed, productivity and is resistant to the industrial environment. Our group carried out a study of probiotic preparations of Bacillus subtilis KATMIRA1933 and Bacillus amyloliquefaciens B-1895 strains. These preparations were made by solid-phase fermentation and tested for dynamical germination of rearing flock (Highsex brown). The … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 4 · 4 Dec 2018 · 9,375 accessesView PDFCite
Research ArticleOpen accessIn the author namesDetermination of the Mutagenicity of 2-aminoanthracene Using Chicken Hepatic S-9 FractionVladimir A. Chistyakov, Alexander V. Usatov, Aleksander I. Klimenko et al.The abundance of potential genotoxins makes it necessary to improve microbial test systems that allow to identify these substances quickly. At the same time, the methodology of metabolic activation of promutagens in vitro is very important. Microsomal preparations of rodents, which are generally used for that, have significant disadvantages associated with the potential health risks of the inducers of the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 16 Nov 2018 · 7,192 accessesView PDFCite
Research ArticleOpen accessIn the author namesComparative Analysis of the Complete Chloroplast Genome of the Alloplasmic Sunflower (Helianthus L.) Lines with Various CMS TypesKirill Azarin, Maxim Makarenko, Alexander Usatov et al.The complete chloroplast genomes of sunflower fertile line HA89 and isonuclear CMS lines with four different cytoplasmic backgrounds (PET1, PET2, ANN2 and MAX) were sequenced. A total of 451 polymorphic sites, with including 58 SSRs, 317 SNPs and 76 microindels were revealed between the fertile and CMS cytotypes. Among the alloplasmic male-sterile lines, cpDNA of CMS-MAX had the largest number … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 2 Mar 2018 · 9,415 accessesView PDFCite
Research ArticleOpen accessIn the author namesAge-Dependent Variation of Telomere Length and DNA Damage in ChickenMaxim S. Makarenko, Alexander V. Usatov, Lyubov V. Getmantseva et al.Birds are unique models for molecular studies on aging processes and cellular senescence because of their slow rates of aging and comparatively long life spans among homoeothermic animals. The study aimed to examine the relative telomere length and amount of nuclear, mitochondrial DNA lesions in hens of different ages and to find out the correlation between these biomarkers of aging. … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Dec 2017 · 7,505 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Investigation of Organelle Genomes of Extra Nuclear Sunflower Mutants with Variegated PhenotypeIrina Dremuk, Nikolay Kozel, Mariya Logacheva et al.The comparative analysis of complete chloroplast and mitochondrial DNA sequences of the original inbred line 3629 and three extra nuclear mutant lines variegated-1, variegated-15, variegated-17, obtained by the N-nitroso-N-methylurea induced mutagenesis, was done. The studied mutant lines were presented two different phenotypes with diverse chlorophyll content: Pale/green mutant line variegated-17 with 1.8% relative (to 3629 line) chlorophyll content in mutant … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,633 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Single and Combined Effect of MC4R and GH Genes on Productive Traits of PigsLyubov Getmantseva, Maria Leonova, Aleksander Usatov et al.The aim of our work is to identify the single and combined effect of MC4R and GH polymorphism genes on growth and reproduction traits of pigs. The study was carried out on 204 crossbred F1 females (♀Landrace х ♂Large White) of the Breeding Farm in Russia.
