Genetic variation in a tepary bean (Phaseolus acutifolius A. Gray) diversity panel reveals loci associated with biotic stress resistance.

Tepary bean (Phaseolus acutifolius A. Gray), indigenous to the arid climates of northern Mexico and the Southwest United States, diverged from common bean (Phaseolus vulgaris L.), approximately 2 million years ago and exhibits a wide range of resistance to biotic stressors.

NAC Candidate Gene Marker for and Interaction With QTL for Resistance to in Common Bean.

Genetic resistance is the primary means for control of (BGYMV) in common bean (). Breeding for resistance is difficult because of sporadic and uneven infection across field nurseries. We sought to facilitate breeding for BGYMV resistance by improving marker-assisted selection (MAS) for the recessive gene and identifying and developing MAS for quantitative trait loci (QTL) conditioning resistance.

Genetic Factors Associated With Nodulation and Nitrogen Derived From Atmosphere in a Middle American Common Bean Panel.

Among grain legume crops, common beans ( L.) are considered to have poor biological nitrogen (N) fixation (BNF) capabilities although variation in N fixing capabilities exists within the species. The availability of genetic panel varying in BNF capacity and a large-scale single nucleotide polymorphism (SNP) data set for common bean provided an opportunity to discover genetic factors associated with N fixation among genotypes in the Middle American gene pool.

Single and Multi-trait GWAS Identify Genetic Factors Associated with Production Traits in Common Bean Under Abiotic Stress Environments.

The genetic improvement of economically important production traits of dry bean ( L.), for geographic regions where production is threatened by drought and high temperature stress, is challenging because of the complex genetic nature of these traits. Large scale SNP data sets for the two major gene pools of bean, Andean and Middle American, were developed by mapping multiple pools of genotype-by-sequencing reads and identifying over 200k SNPs for each gene pool against the most recent assembly of the genome sequence.

A Predictive Model for Time-to-Flowering in the Common Bean Based on QTL and Environmental Variables.

The common bean is a tropical facultative short-day legume that is now grown in tropical and temperate zones. This observation underscores how domestication and modern breeding can change the adaptive phenology of a species. A key adaptive trait is the optimal timing of the transition from the vegetative to the reproductive stage.

Development of a QTL-environment-based predictive model for node addition rate in common bean.

This work reports the effects of the genetic makeup, the environment and the genotype by environment interactions for node addition rate in an RIL population of common bean. This information was used to build a predictive model for node addition rate. To select a plant genotype that will thrive in targeted environments it is critical to understand the genotype by environment interaction (GEI).

Isolates of Rhizoctonia solani Can Produce both Web Blight and Root Rot Symptoms in Common Bean (Phaseolus vulgaris L.).

In common bean (Phaseolus vulgaris L.), Rhizoctonia solani Kühn is an important pathogen causing web blight (WB) in the tropics, and it is also a soilborne pathogen causing root rot (RR) worldwide. This pathogen is a species complex classified into 14 anastomosis groups (AG).

What Latino Puerto Ricans and non-Latinos say when they talk about Alzheimer's disease.

Background: To discover whether Latino Puerto Rican and non-Latino communities differ in the words they use to talk about Alzheimer's disease (AD).

Methods: Four groups of 30 persons per group defined by self-identified ethnicity and caregiver status: Latino Puerto Ricans and non-Latino Whites, who were either caregivers or non-caregivers completed free-listing exercises to identify the words they use when they describe AD causes, symptoms, caregiving, and research risks and benefits.

Results: Both Latino Puerto Ricans and non-Latino Whites recognize AD as a disease of memory loss and other cognitive problems.
