High Level of Nonsynonymous Changes in Common Bean Suggests That Selection under Domestication Increased Functional Diversity at Target Traits
Crop species have been deeply affected by the domestication process, and there have been many efforts to identify selection signatures at the genome level. This knowledge will help geneticists to better understand the evolution of organisms, and at the same time, help breeders to implement successful breeding strategies. Here, we focused on domestication in the Mesoamerican gene pool of Phaseol...
متن کاملDirect and Marker-Assisted Selection for Resistance to Common Bacterial Blight in Common Bean
Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans is a seed-borne disease that can signifi cantly reduce yield and seed quality of common bean (Phaseolus vulgaris L.). Disease resistance is the most effective management strategy, but most common bean cultivars have no CBB resistance. Marker-assisted selection (MAS) shows prom...
متن کاملGenome-wide Association Analysis for Drought Tolerance and Associated Traits in Common Bean.
A genome-wide association study explored the genetic basis of variation for drought tolerance and related traits in a Middle American diversity panel comprising 96 common bean ( L.) genotypes. The panel was grown under irrigated and rainfed conditions and single nucleotide polymorphism (SNP) data were used to explore the genetic diversity and ancestry of the panel. Varying levels of admixtures ...
متن کاملQuantile regression for genome-wide association study of flowering time-related traits in common bean
Flowering is an important agronomic trait. Quantile regression (QR) can be used to fit models for all portions of a probability distribution. In Genome-wide association studies (GWAS), QR can estimate SNP (Single Nucleotide Polymorphism) effects on each quantile of interest. The objectives of this study were to estimate genetic parameters and to use QR to identify genomic regions for phenologic...
متن کاملMapping of QTL for Seed Size and Sliape Traits in Common Bean
Bean seed weight and shape are important traits of different market bean classes. One of the first associations found between a genetic marker and a quantitative trait was reported by Sax ( 1923) for the relationship between seed pigmentation {P gene) and seed weight in common bean. More recently three types of molecular markers have been used to study the genetics of seed weight in common bean...
