  abstract = {{A}cacia senegal and {A}cacia seyal are small, deciduous legume trees, most highly valued for nitrogen fixation and for the production of gum arabic, a commodity of international trade since ancient times. {S}ymbiotic nitrogen fixation by legumes represents the main natural input of atmospheric {N}-2 into ecosystems which may ultimately benefit all organisms. {W}e analyzed the nod and nif symbiotic genes and symbiotic properties of root-nodulating bacteria isolated from {A}. senegal and {A}. seyal in {S}enegal. {T}he symbiotic genes of rhizobial strains from the two {A}cacia species were closed to those of {M}esorhizobium plurifarium and grouped separately in the phylogenetic trees. {P}hylogeny of rhizobial nitrogen fixation gene nif{H} was similar to those of nodulation genes (nod{A} and nod{C}). {A}ll {A}. senegal rhizobial strains showed identical nod{A}, nod{C}, and nif{H} gene sequences. {B}y contrast, {A}. seyal rhizobial strains exhibited different symbiotic gene sequences. {E}fficiency tests demonstrated that inoculation of both {A}cacia species significantly affected nodulation, total dry weight, acetylene reduction activity ({ARA}), and specific acetylene reduction activity ({SARA}) of plants. {H}owever, these cross-inoculation tests did not show any specificity of {M}esorhizobium strains toward a given {A}cacia host species in terms of infectivity and efficiency as stated by principal component analysis ({PCA}). {T}his study demonstrates that large-scale inoculation of {A}. senegal and {A}. seyal in the framework of reafforestation programs requires a preliminary step of rhizobial strain selection for both {A}cacia species.},
