TL;DR: The data clearly indicate a Mesoamerican origin of the common bean and strongly support the occurrence of a bottleneck during the formation of the Andean gene pool that predates the domestication.

TL;DR: The results indicate the occurrence of a strong bottleneck in the Andean wild population before domestication, suggesting a Mesoamerican origin of P. vulgaris and suggest that whole‐genome‐scan approaches are feasible in the common bean.

TL;DR: Gene-based markers were developed that corresponded to genes controlling mutant phenotypes in Arabidopsis thaliana, genes undergoing selection during domestication in maize, and genes that function in a biochemical pathway in A.Thaliana that were determined to be useful for other common Mesoamerican × Andean mapping populations.

TL;DR: The results suggest that because of the complex population structure associated with the ancestral divergence, subsequent bottlenecks in each gene pool, gene pool-specific domestication and intense selection within each gene Pool by breeders; association mapping would best be practised within each common bean gene pool.

TL;DR: It is concluded that population genomics approaches are very efficient in detecting QTLs as most of the markers that are under the effects of selection are linked to known loci related to the domestication syndrome.
