Seed compositional and disease resistance differences among gene pools in cultivated common bean
TLDR
The North Andean gene pool is more like the AndeanGene pool for phaseolin, resistance toangular leaf spot and anthracnose from Andean pathogen isolates, but more likethe Middle American gene pool for lectin, zinc, sulfur and resistance toanthracnosed from Middle American pathogen isolate.
Identifying resistance gene analogs associated with resistances to different pathogens in common bean.
TLDR
The usefulness of RGAs as candidate genes to detect and eventually isolate numerous R genes in common bean is shown, with genetic linkage shown for eight RGAs with partial resistance to anthracnose, angular leaf spot and Bean golden yellow mosaic virus.
Pathogenic variation in, sources of, and breeding for resistance to Phaeoisariopsis griseola causing angular leaf spot in common bean
TLDR
It is suggested that, to breed for durable resistance to ALS, common bean populations should be developed from crosses between Andean and Middle American gene pools, and selected against the broadest range of the most virulent PG isolates of diverse evolutionary origins.
Genetics of angular leaf spot resistance in the Andean common bean accession G5686 and identification of markers linked to the resistance genes
TLDR
This study was conducted to elucidate the genetics of ALS resistance in the Andean accession G5686 using an F2 population derived from a G5698 × Sprite cross, and revealed that three dominant and complementary genes conditioned resistance of G 5686 to P. griseola.
Inheritance and Characterization of Angular Leaf Spot Resistance Gene Present in Common Bean Accession G 10474 and Identification of an AFLP Marker Linked to the Resistance Gene
TLDR
The SCAR marker can only be used to introgress the ALS resistance of G 10474 into Andean backgrounds, and the utility of this marker for marker-assisted selection (MAS) was limited to the Andean gene pool of P. vulgaris.
Genetic variability within Phaeoisariopsis griseola from Central America and its implications for resistance breeding of common bean
TLDR
The genetic and virulence variability of 112 isolates of Phaeoisariopsis griseola, collected from various locations in Central America, were studied using seven random amplified polymorphic DNA (RAPD) primers and 12 common-bean differential genotypes and showed that all isolates belonged to the Mesoamerican group.
Sources of Resistance to Colletotrichum lindemuthianum in the Secondary Gene Pool of Phaseolus vulgaris and in Crosses of Primary and Secondary Gene Pools.
TLDR
High levels of resistance were found in lines that had P. polyanthus as one of the parents in the crosses than in the lines derived from P. coccineus, and these lines constitute a valuable source of resistance and may aid in the development of stable resistance to anthracnose.
Fine-mapping of a major QTL controlling angular leaf spot resistance in common bean (Phaseolus vulgaris L.)
TLDR
A fine-mapping approach of a major quantitative trait locus (QTL) ALS4.1GS, UC for ALS resistance in a mapping population derived from the resistant genotype G5686 and the susceptible cultivar Sprite was reported on.
Inheritance and development of molecular markers linked to angular leaf spot resistance genes in the common bean accession G10909
TLDR
Three sequence-characterized amplified region (SCAR) markers, PF13310, PF9260 and OPE04709, and a microsatellite, Pv-gaat001, segregated in coupling with the resistance genes in G10909, revealed that two dominant and complementary genes conditioned ALS resistance.
Genotypic Characterization of the Common Bean Bacterial Blight Pathogens, Xanthomonas axonopodis pv. phaseoli and Xanthomonas axonopodis pv. phaseoli var. fuscans by rep-PCR and PCR–RFLP of the
TLDR
Cluster analysis of rep-PCR profiles revealed a high level of genetic differentiation between the two CBB pathogens, showing that they are genetically distinct, and significant levels of genetic diversity were observed within each strain, indicating that the two bacteria are not clonal.
