Plant growth-promoting rhizobacteria (PGPR) represent a green solution to emerging food production challenges but the knowledge of their role in shaping phylogenetic and social relationships of bacterial rhizosphere community is lacking. We here address this gap in knowledge by following effects of Bacillus velezensis SQR9, the commercially important PGP rhizobacterium, on rhizosphere community focusing on Bacillus species. Results show that SQR9 dramatically shifts phylogenetic and social relationships in the rhizosphere enriching moderately related and swarming compatible Bacillus species with decreased carbon resource niche overlap. By combining Bacillus isolates from the SQR9 treated rhizosphere with SQR9 into multispecies consortia we confirm in hydroponic systems and soil experiments that relatedness-based sociality and competition for carbon resources represent fundamental knowledge for the intelligent design of efficient PGP consortia. The work contributes toward sustainable agriculture by providing the first insight in PGPR’s sociality effects in the rhizosphere and their importance for PGP consortia design. |
