The taxonomic classification of the wild Lima bean complex needs to be assessed to select species for use in breeding programs and to identify genetic resources for conservation. The objectives of this study were to determine the genetic relationships among, and the phylogeny of, wild Lima bean (...

AFLP fingerprinting of Phaseolus lunatus L. and related wild species from South America
Cultivars of common bean (Phaseolus vulgaris L.) capable of yielding well at low levels of native or added phosphorus (P) are highly desirable in many tropical production systems. The objective of the present study was to identify geographical regions which might be sources of such genotypes. A t...

A geographical approach to identify phosphorus-efficient genotypes among landraces and wild ancestors of common bean
Crop wild relatives that have experienced multiple and independent domestication events provide an excellent model for understanding adaptation processes in crop populations and a first and relevant aspect to investigate is the geographic origin of landraces. The aim of this research was to estab...

Multiple origins of Lima Bean landraces in the Americas: evidence from chloroplast and nuclear DNA polymorphisms
Chloroplast DNA (cpDNA) diversity has been examined using PCR-RFLP and RFLP strategies for phylogenetic studies in the genus Phaseolus. Twenty-two species, including 4 of the 5 cultivated species (P. lunatus L., the Lima bean; P. vulgaris L., the common bean; P. coccineus L., the runner bean and ...

Molecular evidence for an Andean origin and a secondary gene pool for the lima bean (Phaseolus lunatus L.) using chloroplast DNA
Agricultural biodiversity is a strategic asset, particularly for rural people. Agricultural biodiversity has a role in increasing agricultural sustainability, maintaining resilience at the landscape level, facilitating the ability of communities to adapt to a changing climate, improving their die...

Popular press reveals controversy and misconceptions regarding quinoa and food security
Since the domestication of wild plants, farmers have more or less consciously manipulated natural diversity under their specific conditions by selecting new combinations of genes and giving rise to uncounted forms and varieties of crops. Plant breeding is the scientific process that makes use of ...
Background
Humans threat the populations of tree species by overexploitation, deforestation, land use change, and climate change. We present a novel threat assessment at intraspecific level to support the conservation of genetic resources of 80 socioeconomically viable tree species in South Ameri...
