More than two billion people are micronutrient deficient. Polished grains of popular rice varieties have concentration of approximately 2 μg g−1 iron (Fe) and 16 μg g−1 zinc (Zn). The HarvestPlus breeding programs for biofortified rice target 13 μg g−1 Fe and 28 μg g−1 Zn to reach approximately 3...

Arroz más nutritivo contra la desnutrición en América Latina
Background:
Developing new population types based on interspecific introgressions has been suggested by several authors to facilitate the discovery of novel allelic sources for traits of agronomic importance. Chromosome segment substitution lines from interspecific crosses represent a powerful an...

Para marcar los loci que determinan la resistencia al ataque de la bacteriosis común en frijol, se emplearon los polimorfismos en el ADN aleatoriamente amplificado (RAPD), junto con tres diferente metodológicas de análisis génico: análisis de los segregantes diferencialmente agrupados (BSA), sele...

Utilization of new alleles from wild rice species to improve cultivated rice in Latin America
Low soil P availability is a primary constraint to common bean (Phaseolus vulgaris L.) production in Latin America and Africa. Substantial genotypic variation in bean adaptation to low phosphorus (LP) availability has been linked with root traits that enhance the efficiency of soil foraging. The ...

Know your enemy : a novel strategy to develop durable resistance to rice blast fungus through understanding the genetic structure of the pathogen population
Assembled germplasm has provided breeders with valuable traits for the improvement of common beans. Molecular markers such as phaseolin and isozymes have facilitated understanding of the genus Phaseolus thus enabling breeders to develop more effective strategies. However, there are still gaps in ...
