Background: An interesting seed protein family with a role in preventing insect herbivory is the multi-gene, APA family encoding the ?-amylase inhibitor, phytohemagglutinin and arcelin proteins of common bean (Phaseolus vulgaris). Variability for this gene family exists and has been exploited to ...

Micronutrients are essential elements needed in small amounts for adequate human nutrition and include the elements iron and zinc. Both of these minerals are essential to human well-being and an adequate supply of iron and zinc help to prevent iron deficiency anemia and zinc deficiency, two preva...

Climbing common bean (Phaseolus vulgaris L.) genotypes have among the highest yield potential of all accessions found in the species. Genetic improvement of climbing beans would benefit from an understanding of the inheritance of climbing capacity (made up of plant height [PH] and internode lengt...

Tolerance to low P soils is a desirable trait in common bean (Phaseolus vulgaris L.) cultivars grown in acid-weathered soils. Genetic variability in response to P-deficient soils exists in the Andean gene pool. G19833, a low P–tolerant indeterminate Andean landrace, has been evaluated for quantit...

In many low input agricultural systems, phosphorus (P) is one of the most limiting mineral nutrients for plant production. Although applying P fertilizer, if available, is the most performing practice, this should be accompanied by other measures. The use of genetically enhanced plants with impro...

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...
