  abstract = {{A} total of 212 symbiotic bacteria were isolated from nodules of {V}icia ervilia, a traditional crop cultivated in {N}orthern {M}orocco. {T}he isolates were recovered from 10 different sites, trapped each time with the local cultivar grown in the same field. {F}our loci were sequenced in order to characterize the isolates, including two housekeeping genes (rec{A} and gln{II}), one plasmidic symbiotic gene (nod{C}) and one locus from another plasmid (pr{L}11). {I}n several isolates, two different copies of gln{II} were detected and sequenced, suggesting a unique duplication event, which has never been reported previously. {T}here was no correlation between the genetic differentiation among cultivars and among bacteria, showing that the evolution of the bacterial population was independent, at least partially, from the host plant. {B}y placing the haplo-types-in a wide-ranging phylogenetic reconstruction, it was shown that the diversity detected in {M}orocco was spread throughout the different clades detected worldwide. {T}he differentiation between areas relied on frequency variations of haplotypes rather than a presence/absence pattern. {T}his finding raises new questions concerning bacterial genetic resource preservation, and confirms the old tenet "everything is everywhere but the environment selects"},
