  abstract = {{C}rop-to-wild gene flow is a mechanism process widely documented, both in plants and animals. {T}his can have positive or negative impacts on the evolution of admixed populations in natural environments, yet the phenomenon is still misunderstood in long-lived woody species, contrary to short-lived crops. {W}ild olive {O}lea europaea {L}. occurs in the same eco-geographical range as domesticated olive, i.e. the {M}editerranean {B}asin ({MB}). {M}oreover, it is an allogamous and anemophilous species whose seeds are disseminated by birds, i.e. factors that drive gene flow between crops and their wild relatives. {H}ere we investigated the genetic structure of western {MB} wild olive populations in natural environments assuming a homogenous gene pool with limited impact of cultivated alleles, as previously suggested. {W}e used a target sequencing method based on annotated genes from the {F}arga reference genome to analyze 27 western {MB} olive tree populations sampled in natural environments in {F}rance, {S}pain and {M}orocco. {W}e also target sequenced cultivated olive tree accessions from the {W}orldwide {O}live {G}ermplasm {B}ank of {M}arrakech and {P}orquerolles and from an eastern {MB} wild olive tree population. {W}e combined {PCA}, s{NMF}, pairwise {FST} and {T}ree{M}ix and clearly identified genuine wild olive trees throughout their natural distribution range along a north-south gradient including, for the first time, in southern {F}rance. {H}owever, contrary to our assumption, we highlighted more admixed than genuine wild olive trees. {O}ur results raise questions regarding the admixed population evolution pattern in this environment, which might be facilitated by crop-to-wild gene flow.},
