Whole-genome resequencing of common bean elite breeding lines.

The expansion of bean genome technologies has prompted new perspectives on generating resources and knowledge essential to research and implementing biotechnological tools for the practical operations of plant breeding programs. This study aimed to resequence the entire genome (whole genome sequencing-WGS) of 40 bean genotypes selected based on their significance in breeding programs worldwide, with the objective of generating an extensive database for the identification of single nucleotide polymorphisms (SNPs). Over 6 million SNPs were identified, distributed across the 11 bean chromosomes.

Genetic mapping of the Andean anthracnose resistance gene present in the common bean cultivar BRSMG Realce.

The rajado seeded Andean bean ( L.) cultivar BRSMG Realce (striped seed coat) developed by Embrapa expressed a high level of anthracnose resistance, caused by , in field and greenhouse screenings. The main goal of this study was to evaluate the inheritance of anthracnose resistance in BRSMG Realce, map the resistance locus or major gene cluster previously named as , identify resistance-related positional genes, and analyze potential markers linked to the resistance allele.

Whitefly-tolerant transgenic common bean () line.

Common bean ( L.) is a staple food in Brazil with both nutritional and socioeconomic importance. As an orphan crop, it has not received as much research attention as the commodity crops.

Genetic diversity and structure of landrace accessions, elite lineages and cultivars of common bean estimated with SSR and SNP markers.

Common bean (Phaseolus vulgaris L.) is an important source of proteins, fibers and minerals for humans, being grown mainly in developing countries and representing a source of income for small farmers. In this work, a set of 206 Brazilian landraces and 59 elite lineages and cultivars were genotyped with 23 SSR (Simple Sequence Repeats) and 251 SNPs (Single-Nucleotide Polymorphism) markers.

A Review of Angular Leaf Spot Resistance in Common Bean.

Angular leaf spot (ALS), caused by , is one of the most devastating diseases of common bean ( L.) in tropical and subtropical production areas. Breeding for ALS resistance is difficult due to the extensive virulence diversity of and the recurrent appearance of new virulent races.

Genome-Wide Association and Regional Heritability Mapping of Plant Architecture, Lodging and Productivity in .

The availability of high-density molecular markers in common bean has allowed to explore the genetic basis of important complex agronomic traits with increased resolution. Genome-Wide Association Studies (GWAS) and Regional Heritability Mapping (RHM) are two analytical approaches for the detection of genetic variants. We carried out GWAS and RHM for plant architecture, lodging and productivity across two important growing environments in Brazil in a germplasm of 188 common bean varieties using DArTseq genotyping strategies.

SNP discovery in common bean by restriction-associated DNA (RAD) sequencing for genetic diversity and population structure analysis.

Researchers have made great advances into the development and application of genomic approaches for common beans, creating opportunities to driving more real and applicable strategies for sustainable management of the genetic resource towards plant breeding. This work provides useful polymorphic single-nucleotide polymorphisms (SNPs) for high-throughput common bean genotyping developed by RAD (restriction site-associated DNA) sequencing. The RAD tags were generated from DNA pooled from 12 common bean genotypes, including breeding lines of different gene pools and market classes.

Emerging Agricultural Biotechnologies for Sustainable Agriculture and Food Security.

As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security.

Comparative analysis of nutritional compositions of transgenic RNAi-mediated virus-resistant bean (event EMB-PV051-1) with its non-transgenic counterpart.

Golden mosaic is among the most economically important diseases that severely reduce bean production in Latin America. In 2011, a transgenic bean event named Embrapa 5.1 (EMB-PV051-1), resistant to bean golden mosaic virus, was approved for commercial release in Brazil.
