Structure, Functions and Host Control of the Rhizosphere Microbiota - Webex Meeting

Relator: Davide Bulgarelli (Plant Sciences, University of Dundee, James Hutton Institute, United Kingdom)

The rhizosphere, the thin layer of soil tightly adhering to roots, defines a hot spot for microbial colonisation. The microbial community thriving in this environment, collectively referred to  as the rhizosphere microbiota, engages in associations with plant roots involving parasitism, commensalism and mutualism.

Manipulating these interactions is gaining centre-stage in agricultural science as one of the keys to sustainably enhance crop production in the years to come. We previously demonstrated that modern Elite varieties and wild barley ancestors host distinct microbiota, possibly representing a footprint of plant domestication on the microbial communities inhabiting the rhizosphere. We recently extended this line of investigation by characterising the microbiota of a bi-parental population between an elite variety and a wild barley ancestor. By combining microbial sequencing profiles, as ‘quantitative traits’, with barley genomic information we compiled map of the plant loci shaping the rhizosphere microbiota.
