Uromyces appendiculatus in Honduras: Pathogen Diversity and Host Resistance Screening
Acevedo, M., Steadman, J. R., and Rosas, J. C. 2013. Uromyces appendiculatus in Honduras: Pathogen diversity and host resistance screening. Plant Dis. 97:652-661. Bean rust, caused by the fungus Uromyces appendiculatus, is a major constraint for common bean production worldwide. Virulence of U. appendiculatus collected from wild and cultivated Phaseolus spp. was examined in 28 locations across ...
متن کاملFine Mapping of Ur-3, a Historically Important Rust Resistance Locus in Common Bean
Bean rust, caused by Uromyces appendiculatus, is a devastating disease of common bean (Phaseolus vulgaris) in the Americas and Africa. The historically important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen that overcome other rust resistance genes. Existing molecular markers tagging Ur-3 for use in marker-assisted selection produce false results. Here, w...
متن کاملMarker-Assisted Molecular Profiling, Deletion Mutant Analysis, and RNA-Seq Reveal a Disease Resistance Cluster Associated with Uromyces appendiculatus Infection in Common Bean Phaseolus vulgaris L.
Common bean (Phaseolus vulgaris L.) is an important legume, useful for its high protein and dietary fiber. The fungal pathogen Uromyces appendiculatus (Pers.) Unger can cause major loss in susceptible varieties of the common bean. The Ur-3 locus provides race specific resistance to virulent strains or races of the bean rust pathogen along with Crg, (Complements resistance gene), which is requir...
متن کاملDisease-resistance related sequences in common bean.
Primers based on a conserved nucleotide binding site (NBS) found in several cloned plant disease resistance genes were used to amplify DNA fragments from the genome of common bean (Phaseolus vulgaris). Cloning and sequence analysis of these fragments uncovered eight unique classes of disease-resistance related sequences. All eight classes contained the conserved kinase 2 motif, and five classes...
متن کاملMapeamento de Genes de Resistência do Feijoeiro à Ferrugem, Antracnose e Mancha-Angular Usando Marcadores RAPD*
Mapping rust, anthracnose and angular leaf spot resistance genes in common bean using RAPD markers Molecular markers were used to study the organization of rust, anthracnose and angular leaf spot resistance genes in common bean (Phaseolus vulgaris) Ouro Negro cultivar. A segregant population of 154 recombinant inbred lines (RIL ́s) from the crossing between Ouro Negro and Rudá cultivars was inoc...
