If we are to breed common bean (Phaseolus vulgaris L.) for durable resistance to diseases, we must understand pathogenic variation and find sources of resistance. Our first objective was to determine the patterns of pathogenic variation found among isolates of Phaeoisariopsis griseola (PG), the fungus that causes angular leaf spot (ALS) in common bean. We characterized 433 PG isolates from 11 Latin American and 10 African countries, using differential cultivars, isozymes, and/or random…

Sources of resistance to angular leaf spot (Phaeoisariopsis griseola) in common bean core collection, wild Phaseolus vulgaris and secondary gene pool
TLDR
These genotypes from the primary and secondary common bean gene pools resistant to Andean and Mesoamerican races of P. griseola offer a potential for developing broad and durable ALS resistance.
Reaction of selected common bean genotypes to physiological races of phaeoisariopsis griseola occuring in Kenya
TLDR
The results of this study indicate that different bean genotypes have varying levels of resistance to angular leaf spot that can be pyramided into appropriate background to provide durable resistance.
Pathogenic variability in Phaeoisariopsis griseola and response of bean germplasm to different races of the pathogen
TLDR
It is indicated that a number of bean varieties have varying levels of resistance that could be pyramided to provide durable resistance to angular leaf spot and all the resistant or intermediate resistant varieties were of the smallor medium-seeded bean types, whereas the commonly-grown large seeded varieties were generally susceptible.
Characterization of the common bean host and Pseudocercospora griseola, the causative agent of angular leaf spot disease in Tanzania
TLDR
This work aimed at characterizing P. griseola in relation to its host in Tanzania and found that Andean strains of the pathogen and Andean bean genotypes outnumbered Mesoamerican strains.
Virulence, variability and physiological races of the angular leaf spot pathogen Phaeoisariopsis griseola in Kenya
TLDR
The high level of virulence variability in Phaeoisariopsis griseola, the causal agent of angular leaf spot of common bean, implies that multiple sources of resistance are required for effective management of the disease.
Genetic diversity of Pseudocercospora griseola resistance loci in common beans
Common bean ( Phaseolus vulgaris L.) is one of the most widely grown legumes in the world. Although the crop has high yield potential, average yields in Brazil are low due to several diseases.
Response of French bean genotypes to Colletotrichum lindemuthianum and evaluation of their resistance using SCAR markers
TLDR
French bean genotypes were screened in relation to their response to common bean anthracnose in order to identify potential sources of germplasm for breeding and to identify locally improved breeding lines as potential donors for resistance breeding to C. lindemuthianum in Kenya.
Identification of resistance sources of common bean (Phaseolus vulgaris L.) to angular leaf spot (Pseudocercospora griseola)
TLDR
The response of 181 bean genotypes to two angular spot isolates was evaluated to help common bean breeding programs to pyramid genes from the Andean and Mesoamerican gene pools to generate varieties with long-lasting resistance to this disease.
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.

Characterization of variability in the fungus Phaeoisariopsis griseola suggests coevolution with the common bean (Phaseolus vulgaris).
TLDR
RAPD and pathogenicity data suggest that groups 1 and 2 may have originated in the Andes and Mesoamerica, respectively, and that coevolution of the P griseola fungus and its common bean host has resulted in increased levels of disease in this host-pathogen interaction.
New sources of resistance to anthracnose and angular leaf spot of beans (Phaseolus vulgaris L.)
TLDR
Over 13000 CIAT bean accessions were evaluated for their reactions to the anthracnose (Colletotrichum lindemuthianum) and angular leaf spot (Isariopsis griseola) pathogens over a 3 yr period, finding many of these new resistant sources originated in Mexico and Central America.
Angular leaf spot.
TLDR
A great variability of reactions to Mesoamerican races of P. griseola was found between accessions of the core collection, ranging from complete resistance to full susceptibility.
Inheritance of resistance to angular leaf spot (Isariopsis griseola Sacc.) in french bean (Phaseolus vulgaris L.)
TLDR
Study of the F1, F2, and F3 progenies indicated that PLB 257, carries a recessive gene imparting resistance to angular leaf spot, which is a serious disease of French bean in the hills of India.
F1 hybrid weakness in the common bean
TLDR
F, hybrid weakness reflects the geographical isolation of common bean cultivars of the two regions and points to the existence of two separate gene pools in cultivated common bean germplasm.
Mitochondrial DNA polymorphisms of Malawian bean lines: further evidence for two major gene pools
TLDR
These results provide the first evidence that the cytoplasms of the two major germ plasm pools of beans are distinct, and compared to previously observed variability of morphoagronomic characters and isozyme loci.
Identification of presumed ancestral DNA sequences of phaseolin in Phaseolus vulgaris.
TLDR
Amplification and sequencing of members of the multigene family coding for phaseolin provide evidence for accumulation of tandem direct repeats in both introns and exons during evolution of the multi-gene family in this species.
Linkage relationships between genes controlling seed proteins in French bean
TLDR
The inheritance of phaseolin and globulin-2 (G2)/albumin polypeptides was investigated in crosses involving varieties which exhibited the three electrophoretic banding patterns ofphaseolin found in French bean suggesting that the genes controlling each of these groups of polypePTides are closely linked and segregate like single Mendelian genes.
Genetic variation in the subunits of globulin-1 storage protein of French bean
TLDR
Charge and molecular weight heterogeneity of globulin-1 (G1) polypeptides of the bean, Phaseolus vulgaris L., were revealed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) suggesting a genetic and evolutionary relationship.

TLDR
A faster and less prone to contamination procedure by culturing the fungus directly in an Eppendorf tube, and suppressing the phenolization step, as suggested in other recent protocol for plant DNA extraction.
