The origin of common bean was investigated throughout chloroplast and nuclear WGS data considering recombination events. Our results support the Mesoamerican bean. remarkable evolutionary history (Phaseolus vulgaris L.) has led to emergence three wild main gene pools corresponding different eco-geographical areas: Mesoamerica, Andes northern Peru/Ecuador. Recent works proposed novel scenarios, Peru/Ecuador population been described as a new species called P. debouckii, rekindling debate about vulgaris. Here we shed light on by analyzing genomes large varietal collection representing entire geographical distribution forms including Andean individuals. We assembled 37 de novo used them construct time frame for divergence genotypes under investigation, revealing that separation occurred ~ 0.15 Mya. clearly reject recent deboukii hypothesis. These also imply two independent migratory events from Mesoamerica North South Andes, probably facilitated birds. work represents paradigmatic example importance taking into account genetic rearrangements produced when investigating phylogeny analysis studying crop species.
