Fig. 3. Taxonomical composition of microbial communities associated with the S. ciliata rhizosheath–root system and non-vegetated soil.
Relative abundance of (a) bacterial and (b) microeukaryotic phyla/classes associated with rhizosheath–root system compartments (root tissue (RT), rhizosheath (RS) and rhizosphere (RH)) and non-vegetated (NV) soil. Relative abundances are expressed as percentages; star (*) indicates classes belonging to the Proteobacteria phylum; stars (**) indicate classes belonging to the Ascomycota phylum. Gradients of relative humidity and temperature are also schematically reported on the top.
