Abstract Designing effective synthetic microbial communities (SynComs) allows for reconstitution of specific microbiome-associated plant phenotypes, including enhanced growth and tolerance to (a)biotic stresses. In particular, understanding the interplay mechanisms dynamically structuring microbiota assembly functioning wild crop ancestors has been proposed as a novel strategy ‘rewild’ microbiomes health. Here, we profiled phyllosphere green foxtail millet plants collected from seven geographically diverse natural ecosystems showed that variations in soil parameters climatic conditions well genetic distance significantly correlated with bacterial fungal community compositions. Environmental selection was found strongly govern narrow habitat niche breadth, while dispersal limitation predominant displaying broader substrate utilization. Specific yeast genera were identified core taxa based on their abundance prevalence across sampling sites. Moreover, several (Bacillus, Pantoea, Methylobacterium) (Vishniacozyma, Filobasidium, Sporobolomyces) displayed significant correlations abundances one or more foliar pathogenic fungi, particular Alternaria. Subsequent isolation identification these allowed design SynComs protected domesticated leaf infections by Alternaria alternata. These results show fundamental knowledge ancestor large geographic scales can be leveraged cross-kingdom beneficial traits health counterparts.

Abstract The rhizosphere influence on the soil microbiome and function of crop wild progenitors (CWPs) remains virtually unknown, despite its relevance to develop microbiome‐oriented tools in sustainable agriculture. Here, we quantified influence—a comparison between bulk samples—on bacterial, fungal, protists invertebrate communities multifunctionality across nine CWPs at their sites origin. Overall, was higher for abundant taxa four microbial groups had a positive organic C nutrient contents compared soils. microbiomes more important than rare environmental conditions. Our results are starting point towards use engineering modern crops.
