“…In the last five years our group has collected more than 100 wild populations of Phaseolus lunatus in several regions of regions of Mexico. This new material was integrated in recent molecular studies (Serrano-Serrano et al 2012, Andueza-Noh et al 2013, 2015, Martínez-Castillo et al 2014, which demonstrated the existence of two sub-groups, MI and MII, within the Mesoamerican group, and that their divergence could have occurred in the region around the Isthmus of Tehuantepec, Mexico. However, the state of Chiapas, which is located in this region, was subrepresented in the aforementioned studies.…”

“…lunatus, which includes only cultivated populations (Baudet 1977). Recent molecular evidence indicates that the primary gene pool of Lima bean is composed of three main genetic groups: the Andean group (AI); the Mesoamerican MI group and the Mesoamerican MII group (Serrano-Serrano et al 2010, Andueza-Noh et al 2013, 2015. Within each of these groups there are both wild and cultivated populations, and there is evidence of independent domestication events in each of these groups (Debouck et al 1987, Gutiérrez-Salgado et al 1995, Fofana et al 1997, Maquet et al 1997, Caicedo et al 1999, Andueza-Noh et al 2013.…”

Though the west central Mexico and the region between Guatemala and Costa Rica are potential areas of domestication for MI and MII, respectively, the exact areas of domestication are still unknown for both groups (Serrano-Serrano et al 2012, Andueza-Noh et al 2013.…”

“…Knowing the genetic diversity of wild populations of P. lunatus in Mexico is relevant because this country has been identified as an important center of genetic diversity for this species (Martínez-Castillo et al 2004, as well as one of its centers of domestication (Serrano-Serrano et al 2012, Andueza-Noh et al 2013, 2015. The main goal of this work is to contribute to the knowledge of the genetic organization of wild populations of P. lunatus in Mexico, using a molecular study of newly collected populations in the state of Chiapas.…”

Differentiation and genetic diversity of Phaseolus lunatus wild populations from Chiapas, Mexico, and their genetic relationships with MI and MII groups

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. Keywords: Genetic diversity, Genetic resources, Lima bean, Microsatelites, SSR markers, Wild relatives. Diversidad y diferenciación genética de las poblaciones silvestres de Phaseolus lunatus de Chiapas, México, y sus relaciones genéticas con los grupos MI y MII ResumenAntecedentes: Entender la estructura genética de los parientes silvestres de las especies domesticadas es crucial para su conservación y para elucidar los sitios de domesticación de los cultivos. El frijol Lima es una de las cinco especies domesticadas del género Phaseolus y México es uno de sus centros de domesticación. Estudios recientes señalaron dos acervos genéticos silvestres (MI y MII) en México y sugirieron que su divergencia ocurrió en el sureste de México. Pregunta: ¿Los grupos silvestres MI y MII divergieron alrededor del Istmo de Tehuantepec, México? Especie en estudio: El frijol Lima es una especie Neotropical, herbácea, con ciclo de vida anual/corto y tendencia autógama. Sitio y años de estudio: Siete poblaciones silvestres fueron colectadas en 2012 en el Estado de Chiapas, México, área que fue subrepresentada en estudios previos.

Several Mesoamerican crops constitute wild-to-domesticated complexes generated by multiple initial domestication events, and continuous gene flow among crop populations and between these populations and their wild relatives. It has been suggested that the domestication of cotton (Gossypium hirsutum) started in the northwest of the Yucatán Peninsula, from where it spread to other regions inside and outside of Mexico. We tested this hypothesis by assembling chloroplast genomes of 23 wild, landraces, and breeding lines (transgene-introgressed and conventional). The phylogenetic analysis showed that the evolutionary history of cotton in Mexico involves multiple events of introgression and genetic divergence. From this, we conclude that Mexican landraces arose from multiple wild populations. Our results also revealed that their structural and functional chloroplast organizations had been preserved. However, genetic diversity decreases as a consequence of domestication, mainly in transgene-introgressed (TI) individuals (π = 0.00020, 0.00001, 0.00016, 0, and 0, of wild, TI-wild, landraces, TI-landraces, and breeding lines, respectively). We identified homologous regions that differentiate wild from domesticated plants and indicate a relationship among the samples. A decrease in genetic diversity associated with transgene introgression in cotton was identified for the first time, and our outcomes are therefore relevant to both biosecurity and agrobiodiversity conservation.

This review considers which species of beans were domesticated out of a total of 80 or so species in tropical America, and the morpho-and ecological reasons and other nutritional aspects behind the choices of Amerindians who knew and experimented a lot with the fl ora. It explains why places of domestication refer to the locations where seeds of wild forms were picked for the last time. It further shows the current discrepancies between the archaeological records and the genetic data. The seven domestication events affecting the genus Phaseolus, fi ve in Mesoamerica and two in the Andes, seem to have happened originally outside the presence of maize and before the wide use of ceramics, with food uses possibly different from the ones known nowadays (like toasting). The bright idea by Amerindians was to combine maize and beans into a performant agronomic and nutritional association that diffused so widely in pre-Columbian America and set the basis for the many brilliant civilizations they left us.
