Abstract Lima bean ( Phaseolus lunatus L .), one of the five domesticated crops, shows a wide range ecological adaptations along its distribution from Mexico to Argentina. These make it promising crop for improving food security under predicted scenarios climate change in Latin America and elsewhere. In this work, we combine long short read sequencing technologies with dense genetic map biparental population obtain chromosome-level genome assembly bean. Annotation 28,326 gene models show...
Traditional farming communities frequently maintain high levels of agrobiodiversity, so understanding their agricultural practices is a priority for biodiversity conservation. The cultural origin agave spirits (mezcals) from west-central Mexico in the southern part state Jalisco where traditional farmers cultivate more than 20 landraces Agave angustifolia Haw. agroecosystems that include situ management wild populations. These systems, rooted 9000-year-old tradition using agaves as food...
ABSTRACT Phaseolus lunatus L., Lima bean, has been domesticated at least twice in the Americas, once Andean region and another time Mesoamerica; however, domestication history of this crop latter remains unclear. In study, a phylogeographic analysis DNA polymorphisms internal transcribed spacer (ITS) ribosomal from collection wild accessions was applied to establish where how many times Mesoamerica bean domesticated. The results showed evidence for two Mesoamerican gene pools with...
Plant domestication can be seen as a long-term process that involves complex interplay among demographic processes and evolutionary forces. Previous studies have suggested two scenarios for Lima bean in Mesoamerica: separate events, one from gene pool MI central-western Mexico another MII the area Guatemala-Costa Rica, or single followed by post-domestication flow with wild populations. In this study we evaluated genetic structure of tested these competing Mesoamerica applying an ABC...
•Understanding genetic structure in wild relatives of a crop is important for improvement and conservation. Recently, two gene pools (MI MII) were reported Lima bean (Phaseolus lunatus) from Mexico, domestication center Mesoamerican landraces. However, the evidence was based on limited genomic sampling. Here we sought to confirm existence these by increased genome population sampling.•We characterized 67 populations P. lunatus Mexico with 10 microsatellite loci studied means AMOVA, cluster...
The genus Phaseolus , native to the Americas, is composed of more than eighty wild species, five which were domesticated in pre-Columbian times. Since beginning domestication events this genus, ample opportunities for gene flow with relatives have existed. present work reviews extent primary and secondary areas aim illustrating how evolutionary force may conditioned ecological fitness widespread adoption cultigens. We focus on biological bases from a spatial time perspective, dynamics...
ABSTRACT The role of gene flow in autogamous domesticated species diversity and their wild relatives is an issue that requires more field data. Using nine microsatellite loci, analysis was done the magnitude direction wild–weedy–domesticated complex Phaseolus lunatus L. under traditional agricultural conditions four regions on Yucatan Peninsula, Mexico, its center domestication Mesoamerica. Two complementary methods were used. Bayesian genotype assignment approach showed recent low at both...
Lima bean (Phaseolus lunatus L.) is an important source of protein for people as it contributes all the essential amino acids necessary humans. In Brazil, lima has a great relevance, mainly in Northeast, where alternative income addition to food source. It high degree phenotypic variation seed traits, which are understanding genetic diversity and origin this crop. We aimed characterize 166 accessions cultivated from Brazil using qualitative quantitative descriptors through Ward-MLM (Modified...
ABSTRACT This study was conducted to determine the genetic diversity, structure and gene flow of 11 wild populations Phaseolus lunatus L. in four regions traditional agriculture Yucatan Peninsula, Mexico, part putative domestication area its Mesoamerican pool.

Molecular variability of vanilla ( Vanilla planifolia ) and three wild species was assessed to explore the possible sources variation that can be used for crop improvement. A total 154 ISSR loci were analysed by UPGMA, assignment tests individuals (STRUCTURE) indices genetic diversity. The done at two levels: first considering four then only accessions V. . molecular analysis indicated 99.3% polymorphism among all 70.45% within UPGMA showed separation these into groups grouped subgroups....
We evaluated the role of gene flow and wild-crop introgression on structure genetic diversity Lima bean ( Phaseolus lunatus ) in Yucatan Peninsula, an important Mesoamerican area for this crop, using a genotyping-by-sequencing approach (15,168 SNP markers) two scales. At local scale, STRUCTURE NGSEP analyses showed predominantly crop-to-wild introgression, but also evidence bidirectional wild-weedy-crop complexes studied (Itzinté Dzitnup). The ABBA-BABA tests higher Itzinté (the older...
The environmental variability at local scale results in different physiognomic types of mangrove forest. However, this has never been considered studies genetic variability. This study analyzed the and morphological structure Rhizophora mangle regional scales Yucatan Peninsula. Thirteen populations (eight scrub five tall), located seven sites, were sampled, their relationship with availability phosphorus salinity analyzed. diversity estimated hierarchical levels nine microsatellites, also...
Pouteria sapota is known for its edible fruits that contain unique carotenoids, as well fungitoxic, anti-inflammatory and anti-oxidant activity. However, genetics mostly unknown, including aspects about genetic diversity domestication process. We did high-throughput sequencing of microsatellite-enriched libraries P. sapota, generated 5223 contig DNA sequences, 1.8 Mbp, developed 368 microsatellites markers tested them on 29 individuals from 10 populations (seven wild, three cultivated)...
