USING OF SSR MARKERS IN GENETIC STUDIES OF PRUNUS GENUS
DescriptionThis article discusses the actual problem of using SSR-markers in studies of the genus Prunus. We have examined the works on the most important cultures of genus, collected and analyzed contemporary literature of the subject. Data of the initial stage of Prunus SSR-based genetic diversity study in the North-Caucasian region has been described in the presented publication

ДНК-ПАСПОРТИЗАЦИЯ СОВРЕМЕННЫХ РОССИЙСКИХ СОРТОВ РИСА С ПРИМЕНЕНИЕМ SSR-МАРКЕРОВ
DescriptionIn the presented study, we have performed genotyping of modern Russian rice cultivars using microsatellite DNA-markers. The markers showed different level of allelic polymorphism: from 2 to 8 alleles per locus. For all studied cultivars,unique DNA-fingerprints were obtained

VARIETY OF MICROORGANISMS GROUPS LIVING ON BERRIES OF GRAPES
DescriptionThe wide variety of microorganisms has been identified in many wine-making countries on the berries of grapes. These are yeasts of different families, forms and kinds, bacterium, mold fungi. In the article, we present the results of investigating species composition of microflora of berries of white and red types of grape, which grows in different economies of the Krasnodar region and the republic of Abkhaziya. The sowings onto the elective media were conducted for the development of entire spectrum of yeast. The grown colonies after preliminary microscoping were separated into the cultures and subjected to testing according to the culturalmorphological signs, being guided by determinants and benefits. It was established the specific variety of microflora on the surface of the berries of grapes of all investigated types, without dependence on the place of their growth. Obtained data showed that the group of yeast, which constantly is present in the complex of the epiphytic microorganisms of grapes of Saccharomyces, Pichia, Hansenula, Hanseniaspora was characteristic for all types of grapes in all investigated regions. The heterogeneity of the taxonometric composition of microflora is shown. Prevailed yeasts were of family Saccharomycetaceae, form Saccharomyces vini. A quantity of yeast of Saccharomyces vini decreases in a number of Myskhako-Caucasus-Fanagoriya, that as a whole will be coordinated with the climatic conditions. Only the type of Pinot nuar grapes had yeasts of Brettanomyces Dekkera. On the berries of Cabernets and Karaburnu we have discovered yeasts of Schisosaccharomyces acidodevoratus, causing acid-reduction. On the berries of the grapes, which grew in joint stock company APF “Fanagoriya” we haven’t revealed the presence of lactic acid bacteria Lactobacillus brevis and yeasts of the form of Schisosaccharomyces acidodevoratus. In the same farm the smallest quantity of yeastswreckers is noted, which we the forms of Pichia and Candida. In the microflora of Cabernets, Risling and, especially, Karaburnu grapes, we have found lactic acid bacteria Lactobacillus plantarum and Lactobacillus brevis. Lactobacillus plantarum. Among the bacteria the total quantity of coccic flora composes - 56 %, the rod-shaped - 44 %. Two types of active acetous bacteria are identified – Acetobacter aceti and Acetobacter xelinum. Especially high was their surface concentration on the berries of Kachich type of grapes

APPROBATION OF MULTIPLEX SSRANALYSIS FOR DNA-FINGERPRINTS OF RICE VARIETIES
DescriptionResults of testing of multiplex sets SSR-markers for genotyping of rice varieties are presented in the article. Two sets of SSR-markers were formed: 1: RM1+ RM11+ RM70+RM122; 2: RM164+RM167+RM168. The optimal combination of DNA markers in the multiplex sets and PCR conditions allowed obtaining accurate, easily interpretable results when performing fragment analysis on automated genetic analyzer ABIprism3130. Using multiplex sets, genotyping was performed for several varieties of rice: domestic breeding and one variety – IR36 from the breeding of IRRI (Manila, Philippines). For all the studied varieties specific SSR-fingerprints were obtained. RM 168 marker showed in domestic varieties a low level of polymorphism - one allele of 97 bp. However, at the same time, the variety IR-36, showed a second type of allele 107 bp. In addition, the loci of RM1, RM11, RM167 and RM164 have unique alleles in this variety. It is consistent with significant genetic differences of these varieties and the rest of the varieties in studied sample. The proposed SSR multiplexes are promising for use in DNA certification of rice varieties and assessment of genetic diversity

APPROBATION OF MICROSATELLITE DNA-MARKERS FOR IDENTIFICATION OF APPLE CLONES
DescriptionAs the result of the work, the test of microsatellite DNA markers for the identification of genomic polymorphism between apple cultivars Florina, Golden Delicious and clonal forms has been done. With the high level of intervarietal polymorphism, studied DNA markers showed no allelic differences between varieties and their clonal forms

Description
The study was performed to genotype some commercial wine yeast strains using the assay of Interdelta genomic sequences. Experimental parameters of PCR to identify were optimized and optimal simplified method of DNA extraction from dried preparations of yeast cultures was define. Proven method showed a high level of resolution and can be used for the analysis of genetic diversity wine yeast in combination with SSR-markers

APPROBATION OF SSR-ANALYSIS FOR DNA-IDENTIFICATION OF COMMERCIAL WINE YEAST STRAINS
DescriptionThe study was performed to genotype some commercial wine yeast strains with SSR-markers. Five polymorphic SSR-markers were tested in a selection of 15 yeast strains. Tested SSR-markers showed a high level of informativeness as well as polymorphism and can be used further to analyze the genetic diversity of wine yeast

Description
Microsatellite DNA markers are currently used effectively in the study of the genetic diversity of the gene pool of fruit crops and DNA certification of varieties. For plum now there is rather limited list of works on the development of this type of DNA markers. Most often, the search for new SSR-markers for this species is carried out by checking of crossreproducibility of SSR-markers developed in other species of the genus Prunus. In this study, for the 18 SSR-markers previously developed on a peach, there was performed testing and evaluation of the prospects for the use of the genotyping of plum cultivars. Testing was made on the 4 varieties of genetically distant, belonging to the 4 different subspecies of Prunus domestica L., showed the effectiveness of their use. During the study, all tested DNA-markers were grouped together in multiplex sets comprising 3-4 markers. This allows simultaneous genotyping of 3-4 loci in a single PCR reaction. These multiplex kits are available for use in the study of genetic polymorphism of species Prunus domestica L

The study was aimed on approbation of 11 ISSR DNA-markers for their using in DNA fingerprinting of rare plant species of the Western Caucasus Lilium Caucasicum Miscz. Ex Grossh., Galánthus woronowii Kolak., Pancratium maritimum L. according to results DNA-markers set was selected for further using in the investigation of genetic diversity of the mentioned plant species

Description
In the course of the work, 33 ISSR markers were evaluated for efficacy in the detection of genetic changes in regenerants of Galanthus woronowii Losinsk.. Ten markers were found suitable for genotyping according to the species under study. Five samples from the selected ten were analyzed for a sample of 20 plants of regenerants and a mother plant. The obtained data testify to genetic stability of plant material in the process of microclonal propagation
