“…It has been noted that the founder effect associated with recolonization increases the differentiation between subpopulations (Wright 1977). Although all these factors can lead to isolation by distance, our Mantel analysis was not significant and thus did not indicated the existence of such geographical isolation, which has previously been reported for the species (Martínez-Castillo et al 2006, Serrano-Serrano et al 2010. One possible explanation for this result is the existence of admixed accessions, namely accessions possessing ancestry derived from more than one accession as a result of recent gene flow.…”

“…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.…”

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.

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.

“…One of the most important cultural areas of Mesoamerica is the Mayan region which has been divided into two subareas: (1) The Mayan lowlands, which includes the Yucatan Peninsula (Yucatan, Campeche and Quintana Roo) and the state of Tabasco in Mexico, the region of Peten in Guatemala and Belize; and (2) the Mayan highlands, which includes the state of Chiapas in Mexico, Guatemala (except Peten) and the western part of Honduras and El Salvador (Ruz 1981;Garza et al 1996;Sharer 1999). Within the Mayan area, evidence has been found about domestication of regionally important species such as jocote (Spondias purpurea L; Miller and Schaal 2005), scarlet runner bean (P. coccineus L.; Spataro et al 2011) and Lima beans (P. lunatus L.; Andueza-Noh et al 2013).…”

“…lunatus (Baudet 1977). Recent studies indicate the existence of three major gene pools within the species: the Andean (A), Mesoamerican I (MI) and Mesoamerican II (MII), all of which contain wild and domesticated forms (Serrano-Serrano et al 2010Martínez-Castillo et al 2014). Lima beans cultivated in the Yucatán Peninsula are part of the MII gene pool, which constitutes the domesticated forms of Lima beans with the highest richness in the whole Mexico (Ballesteros 1999).…”

Lima bean (Phaseolus lunatus L.) is an important crop in the Mayan culture. The Mayan area, considered as a main center of Mesoamerican diversity, has been divided into two subareas: the Mayan lowlands and the Mayan highlands. The Yucatan Peninsula is part of the Mayan lowlands and holds the highest number of Lima bean landraces of Mexico, but Lima beans are in high risk of genetic erosion due to intensification of the traditional Mayan agriculture. However, information on genetic diversity of Lima beans of the Mayan highlands is lacking. By using 46 landraces collected in the Mayan area (23 from each subarea) and 73 ISSR loci (intersimple sequence repeats), we analyzed the structure, diversity and genetic relationships of Lima beans of this part of Mesoamerica. High levels of diversity (H BAY = 0.45) and genetic structure (F ST = 0.66) were found for the whole Mayan area. Genetic diversity in the Mayan lowlands was apparently higher than the Mayan highlands (H BAY = 0.44 and 0.36, respectively); but differences were not statistically significant. Genetic structure between the subareas was high (AMOVA = 30% of total variation), most landraces grouping according to their geographic origin. This study shows the importance of the Mayan culture in the diversification and conservation of Lima beans. The results provide important information that should be considered when implementing strategies to collect Lima bean landraces and planning in situ and ex situ programs to conserve these landraces in the Mayan region.

“…Phaseolus lunatus L. has been domesticated in the Americas and presents two major gene pools: the Mesoamerican one, with small seeds and wild types distributed in Mexico, Central America and eastern part of the Andes, and the Andean pool, with large seeds and wild types distributed predominantly in the Western part of the Andes, in Ecuador and Northern Peru (GUTIÉRREZ SALGADO et al, 1995;SERRANO-SERRANO et al, 2010). In Brazil, the lima bean is considered I Empresa Brasileira de Pesquisa Agropecuária (Embrapa), Embrapa Recursos Genéticos e Biotecnologia, Brasília, DF, Brasil.…”
