2. Reaction of common bean lines to Xanthomonas axonopodis pv. phaseoli and Curtobacterium flaccumfaciens pv. Flaccumfaciens
Abstract The aim of this study was to evaluate the resistance of 58 common bean lines against common bacterial blight (Xanthomonas axonopodis pv. phaseoli) and bacterial wilt (Curtobacterium flaccumfaciens pv. flaccumfaciens). The experimental design consisted of completely randomized blocks, with four replications per pathogen. The results were subjected to

3. Virulence and molecular characterization of Costa Rican isolates of Rhizoctonia solani from common bean
Web blight is one of the main diseases that affects bean (Phaseolus vulgaris) cultivation. It infects diverse organs at any growth stage of the plant and can be present at different altitudes in a humid tropical climate. The causal agent of this disease is Thanatephorus cucumeris in its sexual stage and Rhizoctonia solani in the anamorph. The objective of th

4. BRS Notável: a medium-early-maturing, disease-resistant Carioca common bean cultivar with high yield potential
BRS Notável is a common bean cultivar with carioca grain, suitable for cultivation in 20 Brazilian states. It is a medium-early-maturing cultivar, with an average yield of 2,261 kg ha-1, 8.5% higher than the controls, a high yield potential (4,472 kg ha-1), lodging tolerance and resistance to anthracnose, fusarium wilt, common bacterial blight, and curtobac

5. Application of semi-selective mediums in routine diagnostic testing of Pseudomonas savastanoi pv. phaseolicola on common bean seeds
Halo blight, caused by Pseudomonas savastanoi pv. phaseolicola (Psp), is considered to be an important bacterial disease on common bean (Phaseolus vulgaris L.) in Serbia. Use of pathogen-free seeds is one of the most effective control measures against this disease. The aim of this study was to evaluate a detection method for Psp on untreated common bean seed

6. Productivity losses among different common bean genotypes caused by common bacterial blight.
Productivity loses caused by plant diseases may reach 100% of the production, depending on the pathogen aggressiveness. Common bacterial blight (CBB), incited by Xanthomonas axonopodis pv. phaseoli (Xap), is among the diseases that may lead to significant losses of productivity to common bean (Phaseolus vulgaris), depending on the prevailing environmental co

7. Virulencia de isolados de Xanthomonas campestris pv. phaseoli (Smith) dye em feijoeiro.
O presente trabalho teve por objetivo avaliar a reacao das folhas e vagens de cinco cultivares de feijoeiro (Phaseolus vulgaris L.) a vinte isolados de Xanthomonas campestris pv. phaseoli. Os experimentos foram conduzidos em condicoes de casa-de-vegetacao (inoculacao foliar) e de estufa (inoculacao em vagem). Pela analise dos resultados, os isolados puderam

8. Indução de resistência em feijoeiro (Phaseolus vulgaris) por acibenzolar-S-metil contra Xanthomonas axonopodis pv. phaseoli: parâmetros bioquímicos e da produção / Induced resistance in bean plants (Phaseolus vulgaris) by acibenzolar-S-methyl against Xanthomonas axonopodis pv. phaseoli: biochemical and production parameters
The common bacterial blight disease of bean caused by the bacterium Xanthomonnas axonopodis pv. phaseoli, occurs mainly in hot and humid regions of the globe. The induced resistance consists in the increase of the plant resistance by the use of external agents, without any change in its genome. The objectives of this study were: (i) to verify the induction o

9. Toward an Integrated Linkage Map of Common Bean. III. Mapping Genetic Factors Controlling Host-Bacteria Interactions
Restriction fragment length polymorphism (RFLP)-based genetic linkage maps allow us to dissect the genetic control of quantitative traits (QT) by locating individual quantitative trait loci (QTLs) on the linkage map and determining their type of gene action and the magnitude of their contribution to the phenotype of the QT. We have performed such an analysis

10. Generalized Induction of Defense Responses in Bean Is Not Correlated with the Induction of the Hypersensitive Reaction.
Transcripts for phenylalanine ammonia-lyase, chalcone synthase, chalcone isomerase, and chitinase accumulated in common bean after infiltration with the Pseudomonas syringae pv tabaci Hrp- mutant Pt11528::Hrp1, even though a hypersensitive reaction did not occur. The temporal pattern of this transcript accumulation was similar to that seen after infiltration

11. Pseudomonas syringae pv. phaseolicola genomic clones harboring heterologous DNA sequences suppress the same phaseolotoxin-deficient mutants.
Cosmid cloning and mutagenesis were used to identify genes involved in the production of phaseolotoxin, the chlorosis-inducing phytotoxin of Pseudomonas syringae pv. phaseolicola, the causal agent of halo blight of bean (Phaseolus vulgaris L.). Eight stable clones were isolated from a genomic cosmid library by en masse mating to 10 ethyl methanesulfonate (EM
