The extent of 5S and 45S ribosomal DNA (rDNA) variation was investigated in wild and domesticated common beans (Phaseolus vulgaris) chosen to represent the known genetic diversity of the species. 5S and 45S rDNA probes were localized on mitotic chromosomes of 37 accessions by fluorescent in situ ...

Four multiplex panels of fluorescent-labeled rice microsatellite markers were designed to survey allelic diversity at a total of 27 simple sequence repeat loci. Automated fragment detection, size calling and binning were used to identify the microsatellite alleles. The panels were tested on 72 ac...

Background: Gene-based (genic) microsatellites are a useful tool for plant genetics and simple
sequence repeat loci can often be found in coding regions of the genome. While EST sequencing
can be used to discover genic microsatellites, direct screening of cDNA libraries for repeat motifs
can save...

Common bean (Phaseolus vulgaris) is the major food legume worldwide, making it an important target for novel approaches of genetic analysis. This study evaluated the use of ethyl methane sulfonate (EMS) for the generation of a mutant population for targeted induced local lesions in genomes (TILLI...

Common bean can be grown as a grain crop (dry beans) or as a fresh vegetable (snap beans/green beans), both items being important in nutritional terms for providing essential minerals and vitamins to the diet. Snap beans are thought to be derived predominantly from dry beans of the Andean genepoo...

Extensive diversity and inter-genepool introgression in a world-wide collection of indeterminate snap bean accessions
Cultivated common bean germplasm is especially diverse due to the parallel domestication of two genepools in the Mesoamerican and Andean centers of diversity and introgression between these gene pools. Classification into morphological races has helped to provide a framework for utilization of th...

The present study describes a new set of 61 polymorphic microsatellite markers for beans and the construction of a genetic map using the BAT93 x Jalo EEP558 (BJ) population for the purpose of developing a reference linkage map for common bean (Phaseolus vulgaris). The main objectives were to inte...

Phytate is an important antinutritional component of legume seeds, which chelates minerals that are essential to the human diet such as iron and zinc. Phytate levels are often correlated with total seed phosphorus (P). The objective of this research was to evaluate quantitative trait loci (QTL) f...
