Description
The article presents the results of the research carried out in 2007-2014. The aim of the study was the composition of the microflora of the leaf surface of some plants of the family Grossulariaceae. Based on these data, the authors distinguish the typical representatives of the leaf surface microflora. The authors study the features of isolated strains interactions

Description
The article deals with the historical aspect of the formation of microbial-plant relationships. We study the details of the way the separate form components of the system "Microorganisms-plant" in the course of evolution. The research is based on the historical analysis of the interactions between microorganisms and plants. As a result of interactions a microbial-plant complex is formed. The article describes some types of interactions between microorganisms and plants. In general, various forms of symbiosis are components of a single evolutionary continuum

MICROBIAL COMMUNITIES OF KARPOSPHAERA AND PHILLOPLAN OF SOME PLANTS OF GROSSULARIACEAE FAMILY
DescriptionThe article presents the results of the research of microflora composition of the leaf surface, the surface of fruit and flowers of Ribes nigrum, R. niveum, R . rubrum and Grossularia reclinata. The research was carried out in the seasonal dynamics from 2007 to 2014. The authors used the method of print for isolating microorganisms from plants. For convenience of calculations and contamination comparison of different environmental niches of plants the number of selected microorganisms was counted on the surface of 1 cm2. It was found out in the article that microorganisms on the surface of lamina are distributed unequally. The number of microorganisms on the bottom surface of the foliage in all periods turned out to be higher. The greatest number of microorganisms was recorded in autumn and reaches the highest value in October. The number of microorganisms on fruit surface increased with ripening and was the highest in July. The quantity on the flowers varies considerably throughout the flowering and is represented minimally compared to other plants niches. The study revealed species-specificity of microorganisms and the host plants. At the same time, long-term study of the microflora of plants belonging to one family made it possible to reveal species that are typical epiphytes

Description
The article presents the results of studying the growth-stimulating activity of the microorganisms of the genus Bacillus of leaf surface microflora arboreal plants in Stavropol. Isolated and identified strains of epiphytic microorganisms of the genus Bacillus with the leaf surface of plants: Quercus robur L., Carpinus caucasica Grossh., Fraxinus excelsior L., Acer campestre L.. Growth stimulating properties of 43 strains of aerobic spore-forming bacteria (Bacillus subtilis, Bac. megaterium, Bac. pumilis, Bac. cereus, Bac. Licheniformis) are researched. Selected strains are potentially promising in the development of microbial preparations for plants. A regional collection of strains of epiphytic organisms was formed
