PLANTS AS AN ECOLOGICAL NICHE FOR HUMAN PATHOGENIC BACTERIA
DescriptionThe facts related to contamination of plants with pathogenic bacteria being a possible source of human foodborne intestinal diseases are discussed. Data bound up with influence of environment conditions with respect to attachment and penetration of bacteria in plant tissues are described. Exquisite results related to the rate of proliferation and the time of retaining enteropathogens in plant organisms are presented

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

THE RESEARCHES IN THE FLOODPLAIN OF THE STEEPE ZONE OF THE KRASNODAR REGION
DescriptionThe article presents the violation of water protection zones. The change in soil fertility. Transparency is linked to the nature of the coating beaches and surface destruction. Surface runoff depends on the vegetation cover. The destruction of vegetation (deforestation, excessive grazing, fire), incorrect plowing surface (along the slope) and tillage farming without following the rules lead to increased erosion, local soil erosion, gully erosion and the rise to an increase in turbidity of rivers. Environmental effectiveness of forest plantations. Prevention of pollution and siltation of river. Improving the sanitary condition of the territory

DEVELOPING OF THE METHODOLOGY FOR THE IDENTIFICATION OF PICEA ABIES L. CLONES BY USING ISSR MARKERS
DescriptionThe technology for the identification of Picea abies L. clones by using ISSR markers was developed. 9 ISSR primers ((GA)9T; (AC)8C; (CA)6RY; (CA)6RG; (CA)6(GT); (CA)6(AC); (AG)8T; (GA)8С и (AG)8YT) were recommended to use for genotypes detection. The selected primers have shown the high level of polymorphism. A total of 172 amplified fragments were found by the selected primers and 149 (86.6%) of them were polymorphic

Description
Based on the information stored in the system of database management, biodiversity indices with special accent on measures of species richness are comparatively studied for Carabid beetles in various areas of the East Caucasus. Biodiversity indices are shown to be dependent on sampling or collecting techniques, sample size, geographic localization and its area
