Are duplicated genes responsible for anthracnose resistance in common bean?
The race 65 of Colletotrichum lindemuthianum, etiologic agent of anthracnose in common bean, is distributed worldwide, having great importance in breeding programs for anthracnose resistance. Several resistance alleles have been identified promoting resistance to this race. However, the variability that has been detected within race has made it difficult to obtain cultivars with durable resista...
متن کاملNew Insights into the Anthracnose Resistance of Common Bean Landrace
The common bean landrace G 2333 carries a three gene pyramid for anthracnose resistance: Co-4 2 , Co-5 and Co-7. The Co-4 2 gene is well characterized but less information is available on Co-5 and Co-7. The objectives of this study were to determine if a new allele of Co-5 is present in G 2333; to characterize the spectrum of resistance conditioned by the Co-7 gene by deriving lines which only ...
متن کاملGenome-Wide Association Study Identifies NBS-LRR-Encoding Genes Related with Anthracnose and Common Bacterial Blight in the Common Bean
Nucleotide-binding site and leucine-rich repeat (NBS-LRR) genes represent the largest and most important disease resistance genes in plants. The genome sequence of the common bean (Phaseolus vulgaris L.) provides valuable data for determining the genomic organization of NBS-LRR genes. However, data on the NBS-LRR genes in the common bean are limited. In total, 178 NBS-LRR-type genes and 145 par...
متن کاملTwo independent quantitative trait loci are responsible for novel resistance to beet curly top virus in common bean landrace G122.
Beet curly top virus, often referred to as Curly top virus (CTV), is an important virus disease of common bean in the semiarid regions of the United States, Canada, and Mexico and the only effective control is genetic resistance. Our objective was to determine if dry bean landrace G122, which lacks the Bct gene for resistance to CTV, contains novel resistance to the virus. Two populations, GT-A...
متن کاملLinkage mapping of the Phg-1 and Co-1 genes for resistance to angular leaf spot and anthracnose in the common bean cultivar AND 277
The Andean common bean AND 277 has the Co-1 and the Phg-1 alleles that confer resistance to 21 and eight races, respectively, of the anthracnose (ANT) and angular leaf spot (ALS) pathogens. Because of its broad resistance spectrum, Co-1 is one of the main genes used in ANT resistance breeding. Additionally, Phg-1 is used for resistance to ALS. In this study, we elucidate the inheritance of the ...
