Microbial-plant interactions in the prevention of environmental risks

摘要

Microbial-plant interactions constitute the basis of life on the Earth. Plants supply oxygen and food for humans, animals, and a considerable part of the microcosm. Microorganisms return nutrients to plants by decomposing and consuming both dead and often living plants as substrates. The latter case may be regarded as parasitism of microorganisms on plants. However, on the whole microorganisms and plants successfully coexist with each other. The importance of the microbial-plant interactions problem can be judged to some extent by the fact that most microorganisms live in the root region of plants. Deforestation considerably reduces the population of microorganisms in soil and changes their qualitative composition.
