THE RHIZOSPHERE MICROBIOME AND ITS BENEFICIAL EFFECTS ON PLANTS – CURRENT KNOWLEDGE AND PERSPECTIVES
Abstract: The root system of a plant works like a factory that produces a huge amount of chemicals to communicate effectively with the microorganisms around it. At the same time, micro-organisms can use these compounds as an energy source. The variety of microorganisms associated with plant roots is enormous, amounting to tens of thousands of species. This complex microbial community, also called the second plant genome, is essential for plant health and productivity. Over the last few years, there has been significant progress in research into the structure and dynamics of the microbial sphere of the rhizosphere. It has been proven that plants shape the composition of microorganisms by synthesizing root secretions. On the other hand, microorganisms play a key role in the functioning of plants through their positive impact on their growth and development. In general, rhizosphere microorganisms promote plant growth directly by providing plants with minerals such as nitrogen and phosphorus and by synthesizing growth regulators, and indirectly, however, by inhibiting the development of various plant pathogens.
