Аннотация:An analysis of literature is given on the following problems: a concept of the rhizosphere and its boundaries, a notion of border cells, the composition and the role of root exudates, the role of ectomycorrhyzal fungi and the biological activity of soils in the rhizosphere, and the specificity of some chemical and physical properties of soils in the rhizosphere. The soil of the rhizosphere is shown to differ significantly from the surrounding soil in most characteristics concerning both the composition of the solid phase and soil solution and the function of individual components of the soil system. The rhizosphere soil has a great number of microorganisms and they have high diversity. The most important specific features of soils in the rhizosphere are related to a continuous input of root exudates, metabolic products of microorganisms and border cells.
The presence of these diverse substances leads to significant changes in the cycles of chemical elements,intensification of the carbon cycle, weathering, and decomposition of organic matter. Some compounds composed root exudates, which promote the microbial synthesis of ethylene—a signal controlling the development of plants—and can cause chemotaxis.
