Introduction
Currently, I'm studying molecular evolution in viruses using single cell sequencing technologies and machine learning approaches.

Article
Glyphosate is the most used herbicide worldwide, with no historical comparison. It is used for genetically modified crops, and particularly in Florida, it is used as a sugar cane ripener. An aquatic formulation (Rodeo®) is used to treat aquatic weeds in waterbodies and drainage canals. Because of its extended use, glyphosate can run off or be spray...

Toxic concentrations of aluminium cations and low phosphorus availability are the main yield-limiting factors in acidic soils, which represent half of the potentially available arable land. Brachiaria grasses, which are commonly sown as forage in the tropics because of their resilience and low demand for nutrients, show greater tolerance to high co...

Background The apomictic reproductive mode of Brachiaria (syn. Urochloa) forage species allows breeders to faithfully propagate heterozygous genotypes through seed over multiple generations. In Brachiaria, reproductive mode segregates as single dominant locus, the apospory-specific genomic region (ASGR). The AGSR has been mapped to an area of reduc...
Article
Full-text available
Several apomictic Brachiaria (Trin.) Griseb. (syn. Urochloa P. Beauv.) species are commercially important tropical forage grasses, but little is known about the interspecific diversity and population structure within this genus. Previously published genus-level Brachiaria phylogenies were conducted with few genotypes and contradicted well-establish...

Adapting to climate risks is central to the goal of increasing food security and enhancing resilience of farming systems in East Africa. We examined farmers’ attitudes and assessed determinants of adaptation using data from a random sample of 500 households in Borana, Ethiopia, Nyando, Kenya, Hoima Uganda, and Lushoto, Tanzania. Adaptation was meas...

Apomixis, asexual reproduction through seed, enables breeders to identify and faithfully propagate superior heterozygous genotypes by seed without the disadvantages of vegetative propagation or the expense and complexity of hybrid seed production. The availability of new tools such as genotyping-by-sequencing and bioinformatics pipelines for specie...

Cultivation of Coffea arabica is highly sensitive to and has been shown to be negatively impacted by progressive climatic changes. Previous research contributed little to support forward-looking adaptation. Agro-ecological zoning is a common tool to identify homolo-gous environments and prioritize research. We demonstrate here a pragmatic approach...
Conference Paper

Se realizó la extracción de ADN de 693 accesiones de Manihot (Qiagen® DNeasy® Plant Mini Kit), entre los que se incluyen muestras de yuca tipo silvestres, criollas y plantas voluntarias, colectadas en diferentes regiones de Colombia; así como muestras control de especies silvestres y clones cultivados de Colombia y otros países, depositados en la U...
Thesis
Full-text available
La yuca (ManihotesculentaCrantz) está distribuida en América, Asia y África; es un producto para el consumo humano utilizado a nivel industrial, donde la producción y calidad nutricional es incrementada mediante mejoramiento convencional y transformación genética. El objetivo de este estudio fue establecer una metodología para la detección del fluj...
