And Function

Soil microbial communities play a very vital role in soil ecosystem as they regulate the biogeochemical cycles. They are also responsible for most of the organic matter decomposition. Therefore a certain change in the climate directly or indirectly influences the structure and function of soil microbial communities in soil, which in turn influence the nutrient cycle in ecosystem. However, little is known about how such increase influences soil microbial communities. In the present review we have focused on the role of the microbial communities in soil ecosystem as well as impact of CO , temperature, precipitation, etc. on soil microbial communities.

ABSTRACT Soil pH is a major factor shaping bulk soil microbial communities. However, it is unclear whether the belowground microbial habitats shaped by plants (e.g. rhizosphere and root endosphere) are also affected by soil pH. We investigated this question by comparing the microbial communities associated with plants growing in neutral and strongly alkaline soils in the Sandhills, which is the largest sand dune complex in the northern hemisphere. Bulk soil, rhizosphere and root endosphere DNA were extracted from multiple plant species and analyzed using 16S rRNA amplicon sequencing. Results showed that rhizosphere, root endosphere and bulk soil microbiomes were different in the contrasting soil pH ranges. The strongest impact of plant species on the belowground microbiomes was in alkaline soils, suggesting a greater selective effect under alkali stress. Evaluation of soil chemical components showed that in addition to soil pH, cation exchange capacity also had a strong impact on shaping bulk soil microbial communities. This study extends our knowledge regarding the importance of pH to microbial ecology showing that root endosphere and rhizosphere microbial communities were also influenced by this soil component, and highlights the important role that plants play particularly in shaping the belowground microbiomes in alkaline soils.
