Crop wild relatives that have experienced multiple and independent domestication events provide an excellent model for understanding adaptation processes in crop populations and a first and relevant aspect to investigate is the geographic origin of landraces. The aim of this research was to estab...

Multiple origins of Lima Bean landraces in the Americas: evidence from chloroplast and nuclear DNA polymorphisms
Common bean (Phaseolus vulgaris) consists of two major geographic gene pools, one distributed in Mexico, Central America, and Colombia and the other in the southern Andes (southern Peru, Bolivia, and Argentina). Amplification and sequencing of members of the multigene family coding for phaseolin,...

Estimation of gene flow on Phaseolus vulgaris L. using molecular markers : Microsatellites and polymorphisms at chloroplast DNA
Chloroplast DNA polymorphisms were studied by PCR sequencing and PCR-restriction fragment length polymorphism in 165 accessions of domesticated landraces of common bean from Latin America and the USA, 23 accessions of weedy beans, and 134 accessions of wild beans covering the entire geographic ra...

The common bean has been part of the Great American Biotic Interchange : Evidence from the study of cpDNA and implications for conservation and breeding
The wild common bean (Phaseolus vulgaris) is widely but discontinuously distributed from northern Mexico to northern Argentina on both sides of the Isthmus of Panama. Little is known on how the species has reached its current disjunct distribution. In this research, chloroplast DNA polymorphisms ...

Origin of year-long bean (Phaseolus dumosus Macfady, Fabaceae) from reticulated hybridization events between multiple Phaseolus species
The genetic variable of seven Phaseolus taxa has been evaluated on the basis of molecular data and the results have used to clarify the phyletic relationships between several taxa of the P. coccineus L. complex. Chloroplast DNA (cpDNA) from 33 populations was digested with six restriction endonuc...

Use of chloroplast DNA polymorphisms for the phylogenetic study of seven Phaseolus taxa including P. vulgaris and P. coccineus
The wild, red-flowered Phaseolus glabellus is generally considered either as a species of the P. coccineus complex or as a subspecies of P. coccineus. Biogeographic considerations as well as experimental hybridization, seed storage protein electrophoresis and cpDNA polymorphism point at its isola...
