Background: Understanding the genetic structure of wild relatives of domesticated species is crucial for its conservation and to elucidate the sites of crop domestication. Lima bean is one of the five domesticated Phaseolus species and Mexico is one of its centers of domestication. Recent studies showed the existence of two wild gene pools (MI and MII) of this species in Mexico and suggested that their genetic divergence occurred in southeast Mexico. Question: Did MI and MII groups diverged around the Isthmus of Tehuantepec, Mexico? Studied species: Lima bean: Neotropical plant species, herbaceous, with an annual/short life cycle and with autogamous tendency. Study site and years of study: Seven wild populations were collected in 2012 in the State of Chiapas, México, area underrepresented in previous studies. Methods: Genetic diversity and grouping patterns of collected populations and their relationship to MI and MII groups were analyzed at eight microsatellite loci. Results: High genetic structure (F ST : 0.42 to 0.96) and a high level of genetic diversity (H E = 0.48) were found. The analyses, and presence of admixed populations in MI and MII, suggested that the genetic divergence of these groups is an ongoing process centered around the Isthmus of Tehuantepec. Conclusions: Our results support the hypothesis that MI and MII groups diverged around the Isthmus of Tehuantepec; however, sampling should be increased both at population and genomic levels, to determine the precise organization of the genetic diversity of wild P. lunatus from Mexico.

“…For the Andean models, domestication began at 10 000 years BP and ended at 4000 years BP. The ending dates were based on the results by Kaplan and Lynch (1999). A variable mutation rate (m, based on a uniform distribution of 1 Â 10 -10 to 1 Â 10 -6 substitutions per synonymous site per year) and a symmetric migration rate (m, between 1 Â 10 -2 to 10 individuals per generation) were included in the simulations.…”

“…Based on the discovery of wild common bean in Argentina (Burkart and Brücher 1953) and Guatemala (McBryde 1947) and archaeological remains found in the Americas (Kaplan and Kaplan 1988;Kaplan and Lynch 1999), common bean is commonly thought to have originated in the Americas. 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.…”

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.

Reanalysis and direct accelerator mass spectrometry radiocarbon dating of the cucurbit assemblage from Coxcatlan Cave provide information on the timing and sequence of the initial appearance of three domesticated plants in the Tehuacá n Valley (Puebla, Mexico) and allow reassessment of the overall temporal context of plant domestication in Mexico. Cucurbita pepo is the earliest documented domesticate in the cave, dating to 7,920 calibrated calendrical (cal) years B.P. The bottle gourd (Lagenaria siceraria) is dated at 7,200 cal years B.P. Cucurbita argyrosperma does not appear until 2,065 cal years B.P. The earlier identification of Cucurbita moschata specimens is not confirmed. Seventy-one radiocarbon dates, including 23 accelerator mass spectrometry dates on cucurbits, provide ample evidence of postdepositional vertical displacement of organic materials in the western half of Coxcatlan Cave, but they also indicate that the eastern half of the cave was largely undisturbed.archaeology ͉ Mexico ͉ cucurbits ͉ agriculture T he shift from a hunting and gathering lifestyle to economies based on domesticated species of plants and animals marks a major transition in human history. This emergence of food production economies occurred independently in Ͼ6 different regions of the world between Ϸ11,000 and 5,000 years ago, as human societies domesticated a wide range of plant and animal species (1, 2). Research on plant and animal domestication and the associated transition to food production has rapidly expanded in recent years because new perspectives, approaches, and technologies are being used in the analysis of plant and animal remains recovered from archaeological contexts (3).Rather than focusing on newly excavated sites, recent research has often involved the reexamination of key museum collections of plant and animal remains that were excavated and initially analyzed decades ago. In Mexico, for example, the most significant advances in understanding the transition to food production in this major center of agricultural origin have resulted from the reanalysis of early domesticated plant assemblages that were recovered in the 1950s and 1960s from cave sites in Tamaulipas (Romero's and Valenzuela's Caves) (4), Puebla (Coxcatlan and San Marcos Caves) (5), and Oaxaca (Guilá Naquitz Cave) (6). These five caves have shaped our understanding of the early history of plant domestication and food production economies in Mesoamerica. Reanalyses of maize (Zea mays) (4, 7-13), bean (Phaseolus sp.) (14), and cucurbit (Lagenaria siceraria and Cucurbita sp.) (4, 15, 16) assemblages from these caves have focused on confirming both their domesticated status (on the basis of clearly defined morphological criteria) and their true age [through accelerator mass spectrometry (AMS) radiocarbon dating], in addition to tracing morphological change and crop selection through time.Direct AMS dating and clear confirmation of domesticated status and taxonomic assignment are also the primary focus for this reanalysis of the cucurbit assemblage ...
