DESCRIPTION:The microbial communities inhabiting the interior of roots of 
 healthy plants\, as well as the rhizosphere\, i.e.\, particles of soil fir
 mly attached to roots\, engage in symbiotic associations with their host. 
 We employed a combination of 16S rRNA gene profiling and shotgun metagenom
 e analysis to investigate the structural and functional diversification of
  the microbiota associated with wild and domesticated accessions of barley
  (Hordeum vulgare). Analyses of beta-diversity based on the 16S data revea
 led a small but significant genotype effect on the root-associated communi
 ties. In addition\, functional characterization of metagenome samples allo
 wed us to identify functional categories enriched in the rhizosphere of ba
 rley as well as protein families with evidence of being under positive sel
 ection. Our results indicate that the combined action of microbe-microbe a
 nd host-microbe interactions drives microbiota differentiation at the root
 -soil interface.\n
