SSU rRNA amplicon analysis of the whole fungal microbiota colonizing B. pinnatum roots. Micro-landscape impacts the fungal microbiota assembly

The study brings new views and ideas on the assembly rules of the plant microbiota (i.e. the fungal microbiota herein).The work originally argues for the consideration of a plant community as a landscape for fungi that may disperse and colonize the different host plants constituting the landscape elements. Based on a large scale mescosm study, it proposes an original combination of landscape ecology methods, analyzing heterogeneity through the composition and configuration of the host plants patchesSSU rRNA amplicon analyses from roots sampled in a mesocosm plant experiment and transposition of landscape ecology analyses to centimetric scale
