  abstract = {{C}ultivated diversity is considered an insurance against major climatic variability. {H}owever, since the 1980s, several studies have shown that climate variability and agricultural changes may already have locally eroded crop genetic diversity. {W}e studied pearl millet diversity in {S}enegal through a comparison of pearl millet landraces collected 40 years apart. {W}e found that more than 20% of villages visited in 1976 had stopped growing pearl millet. {D}espite this, its overall genetic diversity has been maintained but differentiation between early- and late-flowering accessions has been reduced. {W}e also found stronger crop-to-wild gene flow than wild-to-crop gene flow and that wild-to-crop gene flow was weaker in 2016 than in 1976. {I}n conclusion, our results highlight genetic homogenization in {S}enegal. {T}his homogenization within cultivated pearl millet and between wild and cultivated forms is a key factor in genetic erosion and it is often overlooked. {I}mproved assessment and conservation strategies are needed to promote and conserve both wild and cultivated pearl millet diversity.},
