Chloroplast Microsatellite Diversity in Phaseolus vulgaris
Evolutionary studies that are aimed at defining the processes behind the present level and organization of crop genetic diversity represent the fundamental bases for biodiversity conservation and use. A Mesoamerican origin of the common bean Phaseolus vulgaris was recently suggested through analysis of nucleotide polymorphism at the nuclear level. Here, we have used chloroplast microsatellites ...
متن کاملGenetic diversity in local and commercial dry bean (Phaseolus vulgaris) accessions based on microsatellite markers.
Dry beans are considered to be a crop of great socio-economic importance, because they are an inexpensive source of nutrients and because their cultivation requires considerable manual labor. Studies of genetic diversity have been very important for genetic improvement programs, because they give parameters for the identification of genitors that can provide large heterosis effects and improved...
متن کاملChloroplast DNA as an evolutionary marker in the Phaseolus vulgaris
We have analyzed the changes occurring in the chloroplast DNA (cpDNA) of taxa belonging to the Phaseolus vulgaris complex to help clarify relationships among species of this complex. Two restriction maps for 11 restriction enzymes comprising the whole chloroplast genome from a wild P. vulgaris and a wild P. coccineus accession were constructed. These maps allowed us to compare a total of 330 re...
متن کاملPhaseolin nucleotide sequence diversity in Phaseolus. I. Intraspecific diversity in Phaseolus vulgaris.
Most information about the molecular biology of phaseolin, the major seed storage protein in Phaseolus vulgaris, has been obtained from the T-type phaseolin, which is characteristic of the Andean gene pool of the species. In the work reported here, two cDNA clones for the S-type phaseolin representing the other major, Middle American gene pool were isolated and sequenced. Analysis of the DNA se...
متن کاملLandscape genetics, adaptive diversity and population structure in Phaseolus vulgaris.
Here we studied the organization of genetic variation of the common bean (Phaseolus vulgaris) in its centres of domestication. We used 131 single nucleotide polymorphisms to investigate 417 wild common bean accessions and a representative sample of 160 domesticated genotypes, including Mesoamerican and Andean genotypes, for a total of 577 accessions. By analysing the genetic spatial patterns of...
