  abstract = {{F}abeae legumes such as pea and faba bean form symbiotic nodules with a large diversity of soil {R}hizobium leguminosarum symbiovar viciae ({R}lv) bacteria. {H}owever, bacteria competitive to form root nodules ({CFN}) are generally not the most efficient to fix dinitrogen, resulting in a decrease in legume crop yields. {H}ere, we investigate differential selection by host plants on the diversity of {R}lv. {A} large collection of {R}lv was collected by nodule trapping with pea and faba bean from soils at five {E}uropean sites. {R}epresentative genomes were sequenced. {I}n parallel, diversity and abundance of {R}lv were estimated directly in these soils using metabarcoding. {T}he {CFN} of isolates was measured with both legume hosts. {P}ea/faba bean {CFN} were associated to {R}lv genomic regions. {V}ariations of bacterial pea and/or faba bean {CFN} explained the differential abundance of {R}lv genotypes in pea and faba bean nodules. {N}o evidence was found for genetic association between {CFN} and variations in the core genome, but variations in specific regions of the nod locus, as well as in other plasmid loci, were associated with differences in {CFN}. {T}hese findings shed light on the genetic control of {CFN} in {R}lv and emphasise the importance of host plants in controlling {R}hizobium diversity.},
