I Gene

Two 24-mer SCAR primers (SW13) were developed from a previously identified 10-mer RAPD primer (OW13690) linked to the I gene, which conditions resistance to bean common mosaic virus (BCMV) in common bean. Linkage between SW13 and the I gene was tested in three F2 populations segregating for both SW13 and the I gene: N84004/Michelite (1.0 ± 0.7 cM), Seafarer/UI-114 (1.3 ± 0.8 cM), and G91201/Alpine (5.0 ± 2.2 cM). SW13 proved to be more specific and reproducible than the OW13690 RAPD marker. Using different heat-stable DNA polymerases, SW13 amplified a single 690-bp fragment linked to the I gene that more consistently permitted the identification of resistant plants. In addition, the presence of the I gene was detected using SW13 in genotypes originating from different gene pools of Phaseolus vulgaris L., indicating a broad utility of this marker for bean breeding programs.

Bioclimatic Variables

Abiotic stress is a limiting factor for common bean (Phaseolus vulgaris L.) production globally. The study of the genotypic, phenotypic, and bio-climatic variables in a broad set of accessions may assist the identification of genomic regions involved in the climatic adaptation of the common bean. We conducted a genotyping-by-sequencing analysis using 28,823 SNPs on 110 georeferenced common bean accessions from Brazil to discover associations between SNPs and bio-climatic indexes. The population structure analysis clustered the accessions into two groups corresponding to the Andean and Mesoamerican gene pools. Of the 19 bioclimatic variables, 17 exhibited a significant association with SNPs on chromosomes Pv01, Pv02, Pv03, Pv04, Pv06, Pv09, Pv10, and Pv11 of common bean. Ten candidate genes were associated with specific bio-climatic variables related to temperature and precipitation. The candidate genes associated with this significant Pv09 region encode a Platz transcription factor family protein previously reported to be an essential regulator of drought stress. The SNP markers and candidate genes associated with the bio-climatic variables should be validated in segregating populations for water stress, which could further be used for marker-assisted selection. As a result, bean breeding programs may be able to provide advances in obtaining drought-tolerant cultivars.

Pseudocercospora Griseola

Common bean (Phaseolus vulgaris L.) is the most important edible legume in the world and is an important source of income for farmers and food for millions of families. Angular Leaf Spot (ALS), caused by the fungus Pseudocercospora griseola (Sacc.) Ferraris, is one of the most important diseases in the production of common bean with the potential to cause significant seed yield losses. An effective and environmentally friendly alternative to control this disease is the use of improved varieties that combine resistance genes of Andean and Mesoamerican origin. In this study, the response of 181 bean genotypes (coming from different breeding programs of several countries including the USA, Puerto Rico, Honduras, Ecuador, Colombia, Tanzania, Malawi, and Angola) to two angular spot isolates (races 61:11 and 63:51, prevalent in Isabela and Juana Díaz, Puerto Rico) were evaluated. Many of these genotypes contained resistant genes to different biotic and to abiotic stress. A total of 16 lines were identified to have resistance to both races. The resistant lines include the Andean breeding lines CAL 143, 277 and the Mesoamerican cultivar ‘Ouro Negro’ that possess the resistance genes Phg-5, Phg-1, Phg-3, respectively. This information can 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.
