Description
The main contribution to the soil biological properties change in the combined pollution with lead and an alternating magnetic field makes lead pollution. Contribution of the interaction of factors of 20-30%. The contribution of the alternating field was insignificant or unreliable. Black soil and brown forest soils are similar in degree of resistance to the combined pollution. Grey sands have less stability

Description
During cultivation in the glucose-mineral medium, Escherichia coli M-17, O75, № 14 and VL 613 and Salmonella enteritidis excrete amino acids, their composition and dynamics depend on the species and the strain identity. The total concentration of the ami-no acids for probiotic strains was higher than oppor-tunistic. Comparative analysis of the amino acids to their ability to influence the growth of bacteria, sug-gests that amino acids are carry out certain regulatory functions

STABILIZATION OF MRNA CEREALS IN VITRO UNDER THE SILICON INFLUENCE
DescriptionThe differential stability of mRNA is an important mechanism for posttranscriptional regulation of gene expression in eukaryotes. Messenger RNA stability is controlled by specific genes and growth conditions. The review examines the theoretical possibility of mRNA stabilization in vivo as a consequence of replacing carbon atoms (C) or phosphorus (P), composed of nucleic acid on the silicon (Si) atom. During isolation of poly-(A)+mRNA from plant tissues by the two-cycle affinity chromatography on poly-(U)-Sepharose, regular changes in poly- (A)++mRNA yield were observed. The changes varied both with the plant genotype and growth conditions. Celite treatment of heated and unheated total RNA preparations from developing corn kernels and from green and etiolated wheat seedlings. Messenger RNA that differed in the length of poly- (A)-sequences was used for hybridization. It is evident that a reduction of poly-(A)-length causes alterations in spatial structure of mRNA, and associated proteins and cations Mg++ become accessible to celite absorption. Heating promotes melting of secondary structure, already initiated, and increases the efficiency of mRNA stabilization by celite. Interpreting the facts interact celite with mRNA in vitro and stabilization of mRNA in vivo by cycloheximide with a modern point of view can be considered with the position research of the phenomenon of RNA interference

STRUCTURAL AND PHYLOGENETIC ANALYSIS OF VVMYBA1, VVMYBA2 AND VVMYBA3 GRAPEVINE GENES
DescriptionThe article presents the structural and phylogenetic analysis of VIT_02s0033g00410, VIT_02s0033g00390 and VIT_02s0033g00450 genes of the grapevine genome and the closely related orthologous gene MYB114 of the Arabidopsis genome. These genes are responsible for the biosynthesis of anthocyanin in the organs of model plants and are of interest not only for practical production and breeding, but also for fundamental research. These genes were analyzed for GCcomposition of nucleotides, the presence of cisregulatory elements and promoter regions. DNA and protein sequences were aligned to look for similar elements, which allowed further analysis of the ultraconservative domains of four genes. Based on the results of search and identification of the conservative regions, a cluster tree was constructed, which made it possible to identify the separation of gene sidelines from, presumably, the main one. At the same time, the construction of consensus trees based on DNA and protein sequences revealed their absolute similarity. "The Minimal Evolution Tree" allowed calculating the approximate dates of the appearance of the mutations and the divergence times of the gene branches between each other. At the same time, the appearance of the Vitis genus and its separation from the Rosales was taken as the time first divergence point. In the end, homologous metabolic pathways were searched between grapevine and Arabidopsis, which revealed the presence of homologous proteins in the grape proteome. In this turn, it already confirms the existence of similar biosynthetic pathways and, as a consequence, interactions such as "DNA-protein" and "protein-protein"

Description
On the basis of the analysis of morphological indicators of wood cultures of a linden it was recommended to start caring cuts of cultures (the combined method) with removal from low ranks of trees in diameter at height of a breast to 8 sm and from high ranks of 4 trees (24 sm). Intensity of cuts - 35 % from the general number of trunks and 15 % on weight

Description
The article shows the result of the research of algaflora in reservoirs of the Nakhchivan Autonomous Republic of Azerbaijan; it is characterized by high species diversity of algae, it is represented by 135 species, varieties and forms of the two departments. Algoflora basis were 71 species of blue-green and 64 green algae. Among the blue-green algae most personable family is Oscillatoriaceae Kirchn, Microcystidaceae Elenkin and Merismopediaceae Elenk. We have identified the three highest in this kind of algae flora : Oscillatoria Vaucher Ex Gomont, Microcystis Kütz, Merismopedia Meyen. Also, we have identified the three largest in the flora of the Green Algae: Cosmarium Corda. We have found 35 species of Desmidiales, belonging to 8 genera. Ecological and geographical analysis of the flora of algae ponds in the Nakhchivan AR showed the prevalence of plankton, cosmopolitan, mezogalobnyh indifferentnıx, oligogalobnyh, and alkaliphilic
