  abstract = {{E}xtension of land use has been the main way to increase agricultural production to date. {N}atural habitats have consequently decreased and became increasingly fragmented, putting high pressure on the wild relatives of main crops. {I}n this study, we assessed the diversity of wild relatives and cultivated varieties of yam, {D}ioscorea rotundata, a tuber crop grown in {W}est {A}frica. {U}sing nuclear markers, we showed that 19% of the wild plants were in fact hybrids between wild and cultivated varieties. {U}sing whole chloroplast sequences, our results suggest that hybridization may be even stronger, with 43% of the wild individuals presenting either chloroplast or nuclear introgression with the cultivated yams. {A}daptation of agriculture to current new pathogen outbreaks and ongoing climatic changes will require mining the vast diversity found in crops wild relatives. {H}owever, our study suggests that wild yam diversity is already largely tainted by crop-to-wild gene flow. {T}he need to focus on in-situ wild yam conservation is even more crucial, since today, ex-situ genebanks contain nearly no wild yam accessions. {D}ata profile: {M}icrosatellite allele scoring is available as an online appendix; {NGS} data (.bam file) are available as {SRA} bioproject {PRJNA}383673.},
