  abstract = {{T}he {L}aperrine's olive is an iconic subspecies of {O}lea europaea ({O}leaceae) with a narrow distribution in the {S}aharan {M}ountains, from south {A}lgeria to northeast {S}udan. {R}ecently, population genetic and phylogeographic studies gave insights on its reproductive strategies, its history since the {P}leistocene, and its putative utility as a genetic resource of the cultivated olive. {I}n natural habitats, multi-centennial individuals occur in very harsh environmental conditions and mainly reproduce vegetatively, but it appears that sexuality may be easily restored under favourable conditions. {C}rosses between the {L}aperrine's olive and other olive diploid subspecies (subspp. cuspidata and europaea) have been recently reported. {P}lastid {DNA} analyses also indicate that the {L}aperrine's olive has already been used during the secondary diversification of the cultivated {M}editerranean olive in the {M}aghreb. {T}his taxon could therefore be used as source of genes for the breeding of new olive cultivars, particularly to improve drought tolerance. {I}n this review, we also address the potential utility of this taxon for studying the self-incompatibility genetic determinism and the polyploidy origin in {O}. europaea. {P}hylogeographic studies attested that {L}aperrine's olive populations show affinities with both the {M}editerranean and sub-{S}aharan olive taxa, but the high genetic differentiation between populations indicates that gene exchanges between massifs were limited or inexistent for a long time. {D}ating these events remains a challenge for determining in which environmental conditions these populations have been separated. {F}urther comparisons of phylogeographic patterns and reproductive strategies between various plant groups are required to improve knowledge on the biogeography of {S}aharan mountains and may help to define appropriate conservation strategies of their threatened ecosystems.},
