FUNCTIONING OF MICROORGANISMS IN THE RHIZOSPHERE OF PLANTS

Abstract

The functioning of living organisms in nature is possible only due to active interaction with microbiota. It is typical for phytobionts, the microbial cenosis of which is even more diverse. Plants contribute to the spread of microorganisms in the rhizosphere by releasing root exudates. The chemical composition of these exudates varies in different plant species and depends on the significant number of factors that affect their growth and development. The components of the plant root exudates stimulate expansion in the rhizosphere of microorganisms, useful for the plant growth. This microbiota improves the mineral life of plants considerably, stimulating their growth with biologically active compounds, increasing the availability of a number of microelements for them, protecting the growth of plants from phytopathogens and phytophages. It provides significant stimulation for the growth and development of phytobionts. It has been shown that microbial groups in the rhizosphere can induce some changes in the composition of plant root exudates.
