  abstract = {{G}eneration of a complete catalog of transposable elements in the lima bean genome provides insight into the two independent domestication events that occurred in the {M}esoamerican and {A}ndean gene pools of this species. {T}he domestication process in lima bean ({P}haseolus lunatus {L}.) involves two independent events, within the {M}esoamerican and {A}ndean gene pools. {T}his makes lima bean an excellent model to understand convergent evolution. {T}he mechanisms of adaptation followed by {M}esoamerican and {A}ndean landraces are largely unknown. {G}enes related to these adaptations can be selected by identification of selective sweeps within gene pools. {P}revious genetic analyses in lima bean have relied on {S}ingle {N}ucleotide {P}olymorphism ({SNP}) loci, and have ignored transposable elements ({TE}s). {H}ere we show the analysis of whole-genome sequencing data from 61 lima bean accessions to characterize a genomic variation database including {TE}s and {SNP}s, to associate selective sweeps with variable {TE}s and to predict candidate domestication genes. {A} small percentage of genes under selection are shared among gene pools, suggesting that domestication followed different genetic avenues in both gene pools. {A}bout 75% of {TE}s are located close to genes, which shows their potential to affect gene functions. {T}he genetic structure inferred from variable {TE}s is consistent with that obtained from {SNP} markers, suggesting that {TE} dynamics can be related to the demographic history of wild and domesticated lima bean and its adaptive processes, in particular selection processes during domestication.},
