The genus Phytophthora comprises many economically and ecologically important plant pathogens. Hybrid species have previously been identified in at least six of the 12 phylogenetic clades. These hybrids can potentially infect a wider host range and display enhanced vigour compared to their progenitors. Phytophthora hybrids therefore pose a serious threat to agriculture as well as to natural ecosystems. Early and correct identification of hybrids is therefore essential for adequate plant protection but this is hampered...

Data from: Postglacial recolonization history of the European crabapple (Malus sylvestris Mill.), a wild contributor to the domesticated apple

Amandine Cornille, Tatiana Giraud, Céline Bellard, Aurélien Tellier, Bruno Le Cam, Marinus J. Smulders, Jörg Kleinschmit, Isabel Roldán-Ruiz & Pierre Gladieux
Understanding the way in which the climatic oscillations of the Quaternary Period have shaped the distribution and genetic structure of extant tree species provides insight into the processes driving species diversification, distribution and survival. Deciphering the genetic consequences of past climatic change is also critical for the conservation and sustainable management of forest and tree genetic resources, a timely endeavour as the Earth heads into a period of fast climate change. We used a combination...

Data from: Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid

Katrien Vandepitte, Alessandro S. Gristina, Koen De Hert, Tine Meekers, Isabel Roldán-Ruiz & Olivier Honnay
Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related AFLP genetic variation and fitness of all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex to colonization history. Around 1970, D. incarnata suffered a severe bottleneck...

Data from: Detection of airborne genetically modified maize pollen by real-time PCR

Silvia Folloni, Dafni-Maria Kagkli, Bojan Rajcevic, Nilson Guimarães, Fernando H. Valicente, Bart Van Droogenbroeck, Guy Van Den Eede & Marc Van Den Bulcke
The cultivation of genetically modified (GM) crops has raised in the European Union and other parts of the world numerous concerns about their environmental and economic impact. Especially outcrossing of genetically modified organisms (GMO) was from the beginning a critical issue as airborne pollen has been considered an important way of GMO dispersal. Here, we investigate the use of airborne pollen sampling combined with microscopic analysis and molecular PCR analysis as an approach to monitor...

Data from: Canonical correlations reveal adaptive loci and phenotypic responses to climate in perennial ryegrass

José L. Blanco-Pastor, Philippe Barre, Thomas Keep, Thomas Ledauphin, Abraham Escobar-Gutiérrez, Anna Maria Roschanski, Evelyn Willner, Klaus Dehmer, Matthew Hegarty, Hilde Muylle, Elisabeth Veeckman, Klaas Vandepoele, Tom Ruttink, Isabel Roldán-Ruiz, Stéphanie Manel & Jean-Paul Sampoux
Germplasm from perennial ryegrass (Lolium perenne L.) natural populations is useful for breeding because of its adaptation to a wide range of climates. Climate-adaptive genes can be detected from associations between genotype, phenotype and climate but an integrated framework for the analysis of these three sources of information is lacking. We used two approaches to identify adaptive loci in perennial ryegrass and their effect on phenotypic traits. First, we combined Genome-Environment Association (GEA) and GWAS...

Semi-artificial datasets as a resource for validation of bioinformatics pipelines for plant virus detection

Lucie Tamisier, Annelies Haegeman, Yoika Foucart, Nicolas Fouillien, Maher Al Rwahnih, Nihal Buzkan, Thierry Candresse, Michela Chiumenti, Kris De Jonghe, Marie Lefebvre, Paolo Margaria, Jean Sébastien Reynard, Kristian Stevens, Denis Kutnjak & Sébastien Massart
In the last decade, High-Throughput Sequencing (HTS) has revolutionized biology and medicine. This technology allows the sequencing of huge amount of DNA and RNA fragments at a very low price. In medicine, HTS tests for disease diagnostics are already brought into routine practice. However, the adoption in plant health diagnostics is still limited. One of the main bottlenecks is the lack of expertise and consensus on the standardization of the data analysis. The Plant Health...
