The potential of genome-wide RAD sequences for resolving rapid radiations: a case study in Cactaceae
(2020-10-01)
The reconstruction of relationships within recently radiated groups is challenging even when massive amounts of sequencing data are available. The use of restriction site-associated DNA sequencing (RAD-Seq) to this end is ...
Adaptive genetic variation distinguishes Chilean blue mussels (Mytilus chilensis) from different marine environments
(Wiley-Blackwell, 2016)
Chilean mussel populations have been thought to be panmictic with limited genetic structure. Genotyping-by-sequencing approaches have enabled investigation of genomewide variation that may better distinguish populations ...
Tracing the origin of the rocoto chile (Capsicum pubescens):insights through RAD-seq data
(New Phytologist Trust, 2019)
The hot chile Capsicum pubescens is cultivated mainly in the highlands of Central-South America. Unlike other cultivated chiles, C. pubescens is known only as a cultigen and not in the wild. The affinities and origin of ...
RADSex: A computational workflow to study sex determination using restriction site-associated DNA sequencing data
(Wiley-Blackwell, 2021-03-09)
The study of sex determination and sex chromosome organization in nonmodel species has long been technically challenging, but new sequencing methodologies now enable precise and high-throughput identification of sex-specific ...
Genome-wide analysis reveals striking lack of genetic differentiation over long distances for the Antarctic toothfish Dissostichus mawsoni: High genetic connectivity or shared spawning grounds?
(Elsevier Science, 2021-11)
The giant Antarctic toothfish Dissostichus mawsoni is one of the most economically valued fishery resources from the Southern Ocean. However, the distinctive biological characteristics and life history of this species, ...
Investigating the origins and evolution of a glyphosate-resistant weed invasion in South America
(Wiley Blackwell Publishing, Inc, 2021-10)
The global invasion, and subsequent spread and evolution of weeds provides unique opportunities to address fundamental questions in evolutionary and invasion ecology. Amaranthus palmeri is a widespread glyphosate-resistant ...
Early patterns of Andean diversification, genomic and color patterns variation across the Metallura tyrianthina complex of the Northern Andes
The highly variable topography, the climatic history and the great variety of niches of the Andes mountain range have had major contributions to the formation and maintenance of the genetic and morphological diversity of ...
In silico RAD-Seq as a possible tool for ancestry determination : an application in helicobacter pylori
(UniandesMaestría en Biología ComputacionalFacultad de CienciasDepartamento de Biología, 2018)
Helicobacter pylori is a bacterium that has been associated to a diverse range of pathologies that varies from gastritis to gastric cancer. Due to its clinical an evolutionary importance, there has been extensive research ...
Maintaining genetic integrity with high promiscuity: Frequent hybridization with low introgression in multiple hybrid zones of Melocactus (Cactaceae)
(2020-01-01)
Hybridization and introgression between species in contact/hybrid zones provide important insight into the genetic and ecological mechanisms of speciation. Cactaceae represents the most important radiation of true succulent ...
