  abstract = {{J}atropha curcas, a {E}uphorbiaceae species that produces many toxicants, is increasingly planted as an agro-fuel plant in {S}enegal. {T}he purpose of this study was to determine whether soil priming induced by {J}. curcas monoculture could alter the rhizobial populations that nodulate cowpea and acacia, two locally widespread legumes. {S}oil samples were transferred into a greenhouse from three fields previously cultivated with {J}atropha for 1, 2, and 15 years, and the two trap legumes were grown in them. {C}ontrol soil samples were also taken from adjacent {J}atropha-fallow plots. {B}oth legumes tended to develop fewer but larger nodules when grown in {J}atropha soils. {N}early all the nif{H} sequences amplified from nodule {DNA} were affiliated to the {B}radyrhizobium genus. {O}nly sequences from {A}cacia seyai nodules grown in the most recent {J}atropha plantation were related to the {M}esorhizobium genus, which was much a more conventional finding on {A}. seyal than the unexpected {B}radyrhizobium genus. {A}part from this particular case, only minor differences were found in the respective compositions of {J}atropha soil versus control soil rhizobial populations. {L}astly, the structure of these rhizobial populations was systematically imbalanced owing to the overwhelming dominance of a very small number of nif{H} genotypes, some of which were identical across soil types or even sites. {D}espite these weak and sparse effects on rhizobial diversity, future investigations should focus on the characterization of the nitrogen-fixing abilities of the predominant rhizobial strains.},
