Variabilidade entre isolados de Phaeoisariopsis griseola
TLDR
Investigation of the pathogenic variability among P. griseola isolates collected in Minas Gerais state, Brazil finds high variability for anastomosis occurrence among hyphae and ausent clustering among isolates for formation of anASTomosis among Hyphae demonstrating the existence of genetic variability for loci envolved with control this trait.
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.
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.
A Review of Angular Leaf Spot Resistance in Common Bean
TLDR
A comprehensive review of ALS resistance in common bean is provided to provide a reference for future resistance mapping studies and as a guide for the selection of resistance loci in breeding programs aiming to develop common bean cultivars with durable ALS resistance.
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.
Genome-Wide Association Studies of Anthracnose and Angular Leaf Spot Resistance in Common Bean (Phaseolus vulgaris L.)
TLDR
The results indicate a quantitative and complex inheritance pattern for both anthracnose and ALS diseases in common bean, which will contribute to more effective screening of elite germplasm to find resistance alleles for marker-assisted selection in breeding programs.
Distribution and Variability of Pseudocercospora griseola in Uganda
TLDR
The findings indicated the presence of ALS in Uganda with high incidence, severity and variability across districts and altitudes, and strategic interventions involving integrated disease management and breeding for durable resistance are required to manage the disease.
New Andean source of resistance to anthracnose and angular leaf spot: Fine-mapping of disease-resistance genes in California Dark Red Kidney common bean cultivar
TLDR
Genetic analysis of response to ANT and ALS in recombinant inbred lines (RILs) from a CDRK × Yolano cross (CY) showed that the resistance ofCDRK cultivar is conferred by a single dominant loci, which is named CoPv01CDRK/PhgPv 01CDRk, conferring resistance to all races.
Status of Common Bean (Phaseolus vulgaris L.) Diseases in Metekel Zone, North West Ethiopia
TLDR
The common bean production and disease management practices and variety development efforts for the Zone, onwards, should focus on those major disease (such as Angular Leaf Spot, Anthracnose, Floury leaf spot, and Frog Eye leaf spot) in order to sustain production and productivity of common bean cultivars.
Common bean reaction to angular leaf spot comprises transcriptional modulation of genes in the ALS10.1 QTL
TLDR
Findings suggest that common bean reaction to P. griseola involves transcriptional modulation of defense genes in the ALS10.1 locus, contributing to resistance or susceptibility depending on the plant-pathogen interaction.

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.
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.
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.
Identification of a novel source of resistance to angular leaf spot disease of common bean within the secondary gene pool
Phaeoisariopsis griseola (Sacc.) Ferr., the agent of angular leaf spot disease of common bean, is a highly variable pathogen for which resistance gene diversification is required. This study analysed
Angular leaf spot of phaseolus beans: relationships between disease, healthy leaf area, and yield.
TLDR
Yield was not related to disease severity or AUDPC, and HRI is proposed as a key explanatory variable for a transportable system of disease management; it may be useful in producing precise recommendations at the farm level.
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.
Studies on inoculum sources of angular leaf spot of beans caused by Phaeoisariopsis griseola in Uganda
TLDR
It is concluded that the seed, crop debris, off‐season crops and volunteer plants are all possible sources of P. griseola infection under the local conditions.
Effects of Angular Leaf Spot and Rust on Yield Loss of Phaseolus vulgaris.
TLDR
In the 1997 and 1999 experiments, angular leaf spot reached higher disease levels than rust, whereas in 1998, rust was more severe thanangular leaf spot.
Identification of Phaeoisariopsis griseola pathotypes from five States in Brazil
TLDR
Monitoring the pathogenic variability of common bean (Phaseolus vulgaris) in Brazil is the best strategy for a breeding program aimed at developing resistant genotypes, and searching for new resistance genes to angular leaf spot must be pursued.
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.
