InvestigationOpen accessIn the author namesA State of PSI and PSII Photochemistry of Sunflower Yellow-Green Plastome MutantMaksim S. Makarenko, Nikolay V. Kozel, Alexander V. Usatov et al.Chlorophyll deficient mutants are appropriate model objects for a large number of investigations in the field of photosynthesis. In this study, we identified a state of Photosystem I (PSI) and Photosystem II (PSII) photochemistry and light responses of the sunflower yellow-green mutant line - en:chlorina-7, wherein mutations in chloroplast genes have been previously localized. The conducted research revealed low content … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 29 Dec 2016 · 7,462 accessesView PDFCite
Research ArticleOpen accessIn the author namesValidation of SSR markers associated with Submergence Tolerance in Rice (Oryza sativa L.)Kirill V. Azarin, Alexander V. Usatov, Andrey V. Alabushev et al.The present work is devoted to the validation of SSR markers associated with submergence tolerance (Sub1A) QTLs in rice. It was shown that only microsatellite markers RM 7481 differentiates donor lines and recipient variety. Based upon the results of DNA analysis with the marker of the RM 7481 of the F2-plants, the 14 homozygotes by the locus Sub1A, 40 samples … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 19 Dec 2016 · 7,640 accessesView PDFCite
Research ArticleOpen accessIn the author namesVariability of Chloroplast DNA of Extranuclear Sunflower MutantsMarkin Nicolay, Aieksandr Usatov, Maria Logacheva et al.A comparative analysis of full-genome sequences of chloroplast DNA (cpDNA) of the original inbred line 3629 and three extranuclear mutants, which were obtained by the method of mutagenesis induced with N-nitroso-N-methylurea (NMU) and characterized by different level of chlorophyll insufficiency (en:chlorina-7-yellow-green leaves; chlorophyll content (a + b)-67.8% with respect to the line 3629, variegated-10-leaves with white zones; chlorophyll content (a … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Mar 2016 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Salt Stress on Ion Balance at Vegetative Stage in Rice (Oryza sativa L.)Kirill V. Azarin, Andrey V. Alabushev, Alexander V. Usatov et al.Rice (Oryza sativa L.) plants were subjected to NaCl stress within 35 days. The shoot dry weight, root dry weight, total survival percentage and contents of inorganic ions in dry samples of stressed plants were measured to identify the physiological adaptive mechanisms by which rice plants at vegetative stage tolerate salt stresses. Laboratory testing of the 10 rice cultivars showed … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 21 Mar 2016 · 7,472 accessesView PDFCite
Research ArticleOpen accessIn the author namesComparative Genomics of Domesticated and Wild Sunflower: Complete Chloroplast and Mitochondrial GenomesM. S. Makarenko, A. V. Usatov, N. V. Markin et al.The entire chloroplast and mitochondrial genomes of domesticated and wild type sunflower were sequenced. The comparative analysis of chloroplast genomes revealed 43 variant sites, including 21 polymorphic SSR loci and 22 SNPs. About 14 variant sites were found by collation of mitochondrial DNA (mtDNA), among them 4 SSRs, 8 SNPs and 2 deletions. About 9 SNPs were located in coding … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 29 Feb 2016 · 7,778 accessesView PDFCite
Research ArticleOpen accessIn the author namesSSR Analysis of Maternal and Paternal Lines Selected in the Don Region (Russia)N. V. Markin, A. V. Usatov, V. N. Vasilenko et al.Evaluation of DNA polymorphisms of breeding material of sunflower from L.A. Zhdanov Don Experimental Station of oil Crops of V.S. Pustovoit All-Russian Research Institute of Oil Crops represented by 17 maternal (CMS) lines and 12 paternal (Rf) lines was conducted. There were identified 35 allelic variants of CMS lines and 42 allelic variants of Rf lines with use of 11 … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 1 · 16 Jan 2016 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntrogression the SalTol QTL into the Elite Rice Variety of Russia by Marker-Assisted SelectionAlexander Vyacheslavovich Usatov, Andrey Vasilevich Alabushev, Pavel Ivanovich Kostylev et al.The present work is devoted to investigation of the possibility to apply methods of Marker-Assisted Selection (MAS) to introgression the SalTol QTL into genotypes of elite Russian varieties of rice. It was shown that microsatellite markers Rm493, may be effectively used to control transfer the SalTol QTL genes into Russian populations of rice. Based on the highly productive variety “Novator”, … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 18 Nov 2015 · 9,261 accessesView PDFCite
Research ArticleOpen accessIn the author namesLeukemia Inhibitory Factor (LIF) Gene Polymorphism and its Impact on Reproductive Traits of PigsM. A. Leonova, L. V. Getmantseva, V. N. Vasilenko et al.The purpose of this study was to determine the frequencies of alleles and genotypes of the Leukemia Inhibitory Factor (LIF) gene (ID: 399503) in Landrace, Large White and Duroc pigs in Russia and to evaluate the impact on productive traits of pigs.
