Genotypic and environmental effects on seed coat patterning and nutritional composition in common bean (Phaseolus vulgaris L.)

This study examines how genotype and environment affect seed coat patterns and nutritional content in common bean, finding significant environmental impacts on macronutrients and associations between seed coat pigmentation and mineral concentrations.

Novel quantitative trait loci conferring broad-based resistance to root-knot nematodes in lima bean (Phaseolus lunatus)

This study identifies three QTLs conferring resistance to root-knot nematodes in lima beans, with two affecting both nematode species and one specific to M. incognita.

Genotypic and multi-environment phenotypic evaluation of the lima bean USDA National Plant Germplasm System collection

The paper evaluates genotypic and phenotypic traits of lima bean accessions across environments to support breeding, identifying genomic associations and establishing a core collection.

Drone methods and educational resources for plant science and agriculture

The paper describes drone-based phenotyping methods and educational resources for high-throughput plant trait analysis using drone imagery.

A domestication change at PvMYB26 in common bean sheds light on the origins of Middle American agriculture

This study identifies a domestication-related mutation in PvMYB26 in common bean, linking it to reduced pod shattering and suggesting West-Central Mexico as the domestication origin.

QTL Mapping for Pod Quality and Yield Traits in Snap Bean (Phaseolus vulgaris L.)

This study identifies QTL for pod quality and yield traits in snap bean using a RIL population, finding 44 QTL across chromosomes with some novel and overlapping with previous studies.

An empirical evaluation of simulated gastrointestinal digestion platforms for use in plant breeding, using common bean (Phaseolus vulgaris L.) as a model

This study evaluates simulated digestion models to assess bioaccessible nutrient levels in common bean, finding dynamic models outperform static ones in predicting nutrient release.

Selection and adaptive introgression guided the complex evolutionary history of the European common bean

The paper traces the evolutionary history of European common beans, showing Andean origins and adaptive introgression shaping their genomic diversity.
