Abstract Lima bean ( Phaseolus lunatus L .), one of the five domesticated crops, shows a wide range ecological adaptations along its distribution from Mexico to Argentina. These make it promising crop for improving food security under predicted scenarios climate change in Latin America and elsewhere. In this work, we combine long short read sequencing technologies with dense genetic map biparental population obtain chromosome-level genome assembly bean. Annotation 28,326 gene models show...
Common bean ( L.) is the most important grain legume for human consumption and a major nutrition source in tropics. Because production reduced by both abiotic biotic constraints, current breeding efforts are focused on development of improved varieties with tolerance to these stresses. We characterized materials from different programs spanning three continents understand their sequence diversity advance molecular tools. For this, 37 belonging , (A. Gray), L. were sequenced whole-genome...
Accurate detection, genotyping and downstream analysis of genomic variants from high-throughput sequencing data are fundamental features in modern production pipelines for genetic-based diagnosis medicine or selection plant animal breeding. Our research group maintains the Next-Generation Sequencing Experience Platform (NGSEP) as a precise, efficient easy-to-use software solution these features.Understanding that incorrect alignments around short tandem repeats an important source errors, we...
The establishment of Leishmania infection in mammalian hosts and the subsequent manifestation clinical symptoms require internalization into macrophages, immune evasion parasite survival replication. Although many genes involved these processes have been described, genetic genomic variability associated to differences virulence is largely unknown. Here we present variation four (Viannia) panamensis strains exhibiting different levels BALB/c mice its application predict novel related...
Brachiaria grasses are sown in tropical regions around the world, especially Neotropics, to improve livestock production. Waterlogging is a major constraint productivity and persistence of during rainy season. While some cultivars moderately tolerant seasonal waterlogging, none commercial combines superior yield potential nutritional quality with high level waterlogging tolerance. The breeding program at International Center for Tropical Agriculture (CIAT), has been using recurrent selection...
The Common Bean Angular Leaf Spot Resistance Gene Phg-2 was fine-mapped to a 409-Kbp region, and molecular markers for breeders were developed validated in field experiments. bean (Phaseolus vulgaris L.) is an important food legume Latin America, Asia Africa. It source of protein, carbohydrates micro-minerals, particularly smallholder farmers. productivity affected by angular leaf spot (ALS) disease caused the pathogenic fungus Pseudocercospora griseola, resulting significant yield losses,...
Palm oil is the most consumed vegetable globally, and Colombia largest palm producer in South America fourth worldwide. However, plantations are affected by bud rot disease caused oomycete Phytophthora palmivora, leading to significant economic losses. Infection processes plant pathogens involve secretion of effector molecules, which alter functioning or structure host cells. Current long-read sequencing technologies provide information needed produce high-quality genome assemblies, enabling...
Building de novo genome assemblies for complex genomes is possible thanks to long-read DNA sequencing technologies. However, maximizing the quality of based on long reads a challenging task that requires development specialized data analysis techniques. We present new algorithms assembling from haploid and diploid organisms. The assembly algorithm builds an undirected graph with two vertices each read minimizers selected by hash function derived k-mer distribution. Statistics collected...
TILLING (Targeting Induced Local Lesions IN Genomes) is a powerful reverse genetics method in plant functional genomics and breeding to identify mutagenized individuals with improved behavior for trait of interest. Pooled high throughput sequencing (HTS) the targeted genes allows efficient identification sample assignment variants within interest hundreds individuals. Although has been used successfully different crops even applied natural populations, one main issues successful experiment...
Abstract Lima bean ( Phaseolus lunatus L. ) is one of the five domesticated crops, which are essential sources dietary proteins for human consumption. Compared to common P. vulgaris ), it shows a wider range ecological adaptations along its distribution from Mexico Argentina. These and phenotypic plasticity make promising crop improving food security under predicted scenarios climate change in Latin America elsewhere. also an excellent model study convergent evolution adaptive domestication...
