“…This observation is consistent with earlier research (Becerra Velasquez and Gepts 1994;Singh et al 1991b;Freyre et al 1996;McClean et al 2004;McClean and Lee 2007;). For the landraces we analysed, the nucleotide diversity of MA was higher than that the Andean gene pool, similar to earlier studies (Cattan-Toupance et al 1998;Beebe et al 2001;McClean et al 2004;McClean and Lee 2007;Rossi et al 2009).…”

“…Two large gene pools of wild types were identified based on phaseolin seed protein variation Gepts 1990), DNA marker diversity (Becerra Velasquez and Gepts 1994;Sonnante et al 1994;Freyre et al 1996;Tohme et al 1996), morphology (Evans 1976;Gepts and Debouck 1991), isozymes (Koenig and Gepts 1989), mitochondrial DNA variation (Khairallah et al 1992) and amplified fragment length polymorphism (AFLP) (Rossi et al 2009) and short sequence repeats (SSR) ) marker data.…”

“…The presence of distinct groups of landraces has been described at both the morphological (Singh et al 1991a) and molecular level Singh et al 1991b;Becerra Velasquez and Gepts 1994;Freyre et al 1996). Singh et al (1991a) classified the MA cultivars into three races -lowland race Mesoamerican (M) and highland races Durango and Jalisco.…”

Abstract. Multilocus sequence data collected from domesticated and related wild relatives provides a rich source of information on the effect of human selection on the diversity and adaptability of a species to complex environments. To evaluate the domestication history of common bean (Phaseolus vulgaris L.), multilocus sequence data from landraces representing the various races within the Middle American (MA) and Andean gene pools was evaluated. Across 13 loci, nucleotide diversity was similar between landraces and wild germplasm in both gene pools. The diversity data were evaluated using the approximate Bayesian computation approach to test multiple domestication models and estimate population demographic parameters. A model with a single domestication event coupled with bidirectional migration between wild and domesticated genotypes fitted the data better than models consisting of two or three domestication events in each genepool. The effective bottleneck population size was~50% of the base population in each genepool. The bottleneck began~8200 and 8500 years before present and ended at~6300 and~7000 years before present in MA and Andean gene pools respectively. Linkage disequilibrium decayed to a greater extent in the MA genepool. Given the (1) geographical adaptation bottleneck in each wild gene pool, (2) a subsequent domestication bottleneck within each gene pool, (3) differentiation into gene-pool specific races and (4) variable extents of linkage disequilibrium, association mapping experiments for common bean would more appropriately be performed within each genepool.

“…These two gene pools are characterized by partial reproductive isolation (3,4), and they are seen in both wild and domesticated materials. They have been recognized in several studies based on morphology (5-7), agronomic traits (7), seed proteins (8), allozymes (9), and different types of molecular markers (10)(11)(12)(13)(14)(15), which have given the overall indication of the occurrence of at least two independent domestication events in the two different hemispheres. The existence of these two geographically distinct and isolated evolutionary lineages that predate the domestication of the common bean represents a unique scenario among crops.…”

“…Moreover, wild populations from Colombia are often seen as intermediates, and a marked geographical structure is observed in wild beans from Mesoamerica (12). The population from northern Peru and Ecuador is usually considered the ancestral population from which P. vulgaris originated (the northern Peru-Ecuador hypothesis) (11,24,25). Indeed, the work by Kami et al (24) analyzed a portion of the gene that codes for the storage seed protein phaseolin, including phaseolin type (type I) from northern Peru-Ecuador accessions that was not present in the other gene pools, which indicates that type I phaseolin is ancestral to the other phaseolin sequences of P. vulgaris (24).…”

Knowledge about the origins and evolution of crop species represents an important prerequisite for efficient conservation and use of existing plant materials. This study was designed to solve the ongoing debate on the origins of the common bean by investigating the nucleotide diversity at five gene loci of a large sample that represents the entire geographical distribution of the wild forms of this species. Our data clearly indicate a Mesoamerican origin of the common bean. They also strongly support the occurrence of a bottleneck during the formation of the Andean gene pool that predates the domestication, which was suggested by recent studies based on multilocus molecular markers. Furthermore, a remarkable result was the genetic structure that was seen for the Mesoamerican accessions, with the identification of four different genetic groups that have different relationships with the sets of wild accessions from the Andes and northern Peru–Ecuador. This finding implies that both of the gene pools from South America originated through different migration events from the Mesoamerican populations that were characteristic of central Mexico
