Data from: How to escape from crop-to-weed gene flow: phenological variation and isolation-by-time within weedy sunflower populationsMarie Roumet, Camille Noilhan, Muriel Latreille, Jacques David, Marie-Hélène Muller & M.-H. Muller
The evolution of crop-related weeds may be constrained by recurrent gene flow from the crop. However, flowering time variation within weedy populations may open the way for weed adaptation by allowing some weeds to escape from this constraint. We investigated this link between phenology, gene flow and adaptation in weedy sunflower populations recently emerged in Europe from crop-wild hybridization. We studied jointly flowering phenology and genetic diversity for 15 microsatellite loci in six cultivated sunflower...
Nucleotide landscapes, which is the way base composition is distributed along a genome, strongly vary among species. The underlying causes of these variations have been much debated. Though mutational bias and selection were initially invoked, GC-biased gene conversion (gBGC), a recombination-associated process favoring the G and C over A and T bases, is increasingly recognized as a major factor. As opposed to vertebrates, evolution of GC content is less well known in plants. Most studies...
Data from: Genome scans reveal candidate regions involved in the adaptation to host plant in the pea aphid complexJulie Jaquiéry, Solenn Stoeckel, Pierre Nouhaud, Lucie Mieuzet, Frédérique Mahéo, Fabrice Legeai, Nina Bernard, Antoine Bonvoisin, Renaud Vitalis & Jean-Christophe Simon
A major goal in evolutionary biology is to uncover the genetic basis of adaptation. Divergent selection exerted on ecological traits may result in adaptive population differentiation and reproductive isolation and affect differentially the level of genetic divergence along the genome. Genome-wide scan of large sets of individuals from multiple populations is a powerful approach to identify loci or genomic regions under ecologically divergent selection. Here, we focused on the pea aphid, a species complex of...
Data from: Inferences on population history of a seed chalcid wasp: invasion success despite a severe founder effect from an unexpected source populationMarie-Anne Auger-Rozenberg, Thomas Boivin, Emmanuelle Magnoux, Claudine Courtin, Alain Roques & Carole Kerdelhué
Most invasive species established in Europe originate from either Asia or North America, but little is currently known about the potential of the Anatolian Peninsula (Asia Minor) and/or the Near East to constitute invasion sources. Mediterranean forests are generally fragile ecosystems that can be threatened by invasive organisms coming from different regions of the Mediterranean Basin, but for which historical data are difficult to gather and the phylogeographic patterns are still poorly understood for most...
Data from: Next-generation sequencing for rodent barcoding: species identification from fresh, degraded and environmental samplesMaxime Galan, Marie Pagès & Jean-François Cosson
Rodentia is the most diverse order among mammals, with more than 2,000 species currently described. Most of the time, species assignation is so difficult based on morphological data solely that identifying rodents at the specific level corresponds to a real challenge. In this study, we compared the applicability of 100 bp mini-barcodes from cytochrome b and cytochrome c oxidase 1 genes to enable rodent species identification. Based on GenBank sequence datasets of 115 rodent species,...
