Summary of the represented taxa and their diversity in loosely attached and rhizosphere soil of cultivated and wild Oryza species. a — Bar graph showing the representation of the most highly represented phyla in the soils. Proteobacteria, as the most abundant phylum, are subdivided into classes. b — Boxplots representing the range of alpha diversity (Faith’s phylogenetic diversity) in loosely attached soil or rhizosphere of cultivated and wild Oryza species. Species diversity is reduced in the rhizosphere compared to the loose soil. Wild Oryza rhizosphere appears less diverse than the other sample types
