“…The presence of a plant not only promotes the growth of soil microbial communities directly but also influences the abiotic properties that influence their growth indirectly (Singh et al, 2009). Other studies have suggested that soil characteristics (Girvan et al, 2003) and the geographic factors are the most important factors in shaping the structure of the soil microbial communities; however, soil microorganisms can also have a significant effect on the formation of soil aggregates (Tisdall, 1996;Bronick & Lal, 2005).…”

Microbial soil communities are active players in the biogeochemical cycles, impacting soil fertility and interacting with aboveground organisms. Although soil microbial diversity has been studied in good detail, the factors that modulate its structure are still relatively unclear, especially the environmental factors. Several abiotic elements may play a key role in modulating the diversity of soil microbes, including those inhabiting the rhizosphere (known as the rhizosphere microbiome). This review summarizes relevant and recent studies that have investigated the abiotic factors at different scales, such as pH, temperature, soil type, and geographic and climatic conditions, that modulate the bulk soil and rhizosphere microbiome, as well as their indirect effects on plant health and development. The plantmicrobiome interactions and potential benefits of plant growth-promoting rhizobacteria are also discussed. In the last part of this review, we highlight the impact of climate change on soil microorganisms via global temperature changes and increases in ultraviolet radiation and CO 2 production. Finally, we propose the need to understand the function of soil and rhizospheric ecosystems in greater detail, in order to effectively manipulate or engineer the rhizosphere microbiome to improve plant growth in agricultural production.Additional key words: abiotic interactions; plant growth-promoting rhizobacteria; rhizosphere microbiome; soil.Correspondence should be addressed to Gustavo Santoyo: gsantoyo@umich.mx

“…Various studies have shown that soil properties influenced microbial communities (Lauber et al, 2008;Singh et al, 2009;Kuramae et al, 2012). In this study, we found that the relative abundance of bacterial families was strongly affected by the differences between the soil properties of ADE and ADJ.…”

“…In this study, we found that the relative abundance of bacterial families was strongly affected by the differences between the soil properties of ADE and ADJ. One of the main drivers of change in the abundance of the selected bacterial families was soil pH, which is well known to affect soil bacterial communities (Lauber et al, 2009;Singh et al, 2009;Nacke et al, 2011). The strong correlation between Gaiellaceae, Gemmataceae and Syntrophobacteriaceae with soil P also appeared to favor an increase in the abundance of these bacterial groups.…”

Amazonian Dark Earth (ADE) in the BrazilianAmazon is the main evidence left by pre-Columbian indigenous populations indicating that infertile soils can be transformed into highly fertile ground. Changes in vegetation cover and seasonality are likely to influence microbial communities; however, little is known about these effects on ADE. Therefore, this study compared the effects of two land use systems in ADE and adjacent soil (ADJ) during the rainy and dry seasons using biochemical and molecular tools. Bacterial community function was determined by community level physiological profile (CLPP), bacterial community structure by terminal restriction length polymorphism (T-RFLP), and bacterial community composition by pyrosequencing of the V4 16S rRNA gene region. Our results show that the community structure is highly affected by vegetation, in both, ADE and ADJ soils. Regarding community function, Average Well Color Development (from Biolog substrates) were higher in ADE than ADJ during the rainy season and kept the same pattern of substrate utilization during the dry season and finally, community composition showed to be influenced even at the level of family, mostly by soil type rather than vegetation. Collectively, our study provides insights into processes affecting the bacterial community assemblages in both, ADE and adjacent soils.

“…Plant cover affects microbial communities because of the quality and amount of leaf and root litter together with root exudates (Wallenius et al, 2011). In addition to the direct effects of litter on microbial communities, land use change can indirectly affect soil microbial composition through alterations in soil properties like soil density, infiltration and evaporation of water, moisture and bioavailability of nutrients (Young and Crawford, 2004;Singh et al, 2009;Wakelin et al, 2008;Wallenius et al, 2011). However, the way in which these factors would influence the structure of a given community remains unclear.…”

Land use change is one of the the major factors related to soil degradation and alterations in soil microbial diversity and structure. In this study, we aimed to evaluate the microbial shifts caused by deforestation of a small area of a natural forest for the introduction of a pasture in the Brazilian Pampa. The microbial abundance and structure were evaluated by molecular approaches based on quantitative Polymerase Chain Reaction (qPCR) and Ribosomal Intergenic Spacer Analysis (RISA). The microbial communities did not present significant quantitative differences, but the environmental impact caused by deforestation changed the structure of the bacterial and archaeal communities. Taking into account the percentage of shared OTUs (operational taxonomic units) of each domain evaluated, we concluded that the domain Bacteria were more influenced by the deforestation than the Archaea. A total of 22 % of bacterial OTUs and 50 % of the archaeal OTUs were shared between forest and grassland leading us to conclude that the environment evaluated presented a core microbial community that did not suffer modification caused by land use change.
