  abstract = {{A}cacia senegal ({L}.) {W}illd. is the main species producing the internationally traded gum arabic. {G}enetic studies of this species are rare and until now the chromosome number was thought to be diploid (2n = 2x = 26). {H}ere, using chromosome number counting, we demonstrate for the first time that tetraploids (2n = 4x = 52) also occur in {A}. senegal. {N}uclear and chloroplast microsatellite markers were used to estimate and compare genetic variation within this newly described polyploidy complex in the {S}udano-{S}ahelian region in {A}frica. {G}enetic diversity was higher in diploids, suggesting that the formation of tetraploids is recent and that mutation-drift equilibrium has not yet been reached. {T}he two cytotypes do not have the same genetic structure and are genetically differentiated. {A}mong tetraploids, populations are greatly differentiated and do not share the same chlorotypes. {B}ased on these results, we discuss recurrent formation of tetraploids from different diploid progenitors across the distribution range of {A}. senegal in the {S}udano-{S}ahelian zone.},
