ABSTRACT Soil microbes play pivotal roles in the multifunctioning of terrestrial ecosystems. In context global changes, there is an urgent need to protect soil microbial diversity, which relies on determining abiotic and biotic factors that influence composition, assemblage microbiota. A large number informative studies have reported edaphic properties climate as key drivers bacteria However, these were mainly conducted at phylum level based a restricted non-microbial variables. this study, we aimed estimate relative effects shaping bacterial communities diverse taxonomic levels by focusing 160 natural sites located southwest France for unique set variables available. After characterizing with highly taxonomically resolving gyrB gene, identified addition pH, temperature, precipitations, lowest appear strongly structured micronutrients, notably manganese. On other hand, highest interplay between descriptors plant properties. Similar previous observations pathogens, strong positive associations species presence particular suggest host specificity commensal bacteria. Altogether, deeper characterization both could help fuel programs designed protecting restoring ecosystem functions.

In the last decade, generation of host-associated microbial culture collections has allowed fine disentangling complex relationships between commensal microbes and their hosts, within-microbiota interactions. Specifically, these have been used to construct synthetic communities (SynComs), which allow reconstruction host microbiota in laboratory conditions. three recent perspective publications, importance this tool highlighted, ground rules utilization designing such SynComs laid out. It is important note that although are understand intricate ecological interactions occurring natural conditions, intraspecific genetic diversity present seldom considered design interspecific so far. Viewpoint, we therefore argue could benefit from developments plant communities, or SynComs. For instance, considering its effects on intra- plant-plant appears essential better predict highly productive stable communities. Therefore, within species undoubtedly represents an exciting opportunity innovative
