Data from: Assessing early fitness consequences of exotic gene flow in the wild: a field study with Iberian pine relictsGregor M. Unger, Myriam Heuertz, Giuseppe G. Vendramin & Juan J. Robledo-Arnuncio
Gene flow from plantations of nonlocal (genetically exotic) tree provenances into natural stands of the same species is probably a widespread phenomenon, but its effects remain largely unexamined. We investigated early fitness consequences of intraspecific exotic gene flow in the wild by assessing differences in survival among native, nonlocal, and F1 intraspecific hybrid seedlings naturally established within two native pine relicts (one of Pinus pinaster and the other of P. sylvestris) surrounded by nonlocal plantations....
Data from: Halfway encounters: meeting points of colonization routes among the southern beeches Nothofagus pumilio and N. antarcticaCarolina Soliani, Yoshiaki Tsuda, Francesca Bagnoli, Leonardo A. Gallo, Giovanni G. Vendramin & Paula Marchelli
The Patagonian region is characterized by a complex biogeographic history, with evidence of deep phylogeographic breaks shared among species. Of particular interest to conservation is the nature of colonization and settlement patterns after the last glacial period, including the detection of secondary contact between different lineages and/or hybridization among related species around phylogeographic breaks. Here we studied population demography and past hybridization of two widespread tree species endemic to South America, Nothofagus pumilio and N....
In this study, new chloroplast (cp) resources were developed for the genus Cynara, using whole cp genomes from 20 genotypes, by means of high-throughput sequencing technologies. Our target species included seven globe artichokes, two cultivated cardoons, eight wild artichokes, and three other wild Cynara species (C. baetica, C. cornigera, and C. syriaca). One complete cp genome was isolated using short reads from a whole genome sequencing project, while the others were obtained by means of...
Data from: \"Diagnostic SNPs for inferring population structure in American mink (Neovison vison) identified through RAD sequencing\" in Genomic Resources Notes accepted 1 October 2014 to 30 November 2014Janne Pia Thirstrup, Aritz Ruiz-Gonzalez, Jose Martin Pujolar, Peter Foged Larsen, Rasmus O. Nielsen, Ettore Randi, Andrzej Zalewski, Cino Pertoldi, Mariella Baratti, Tiziana Di Lorenzo, Alessio Iannucci, Diana Maria Paola Galassi, Valentina Iannilli, Just Jensen, Dragos Postolache & Giovanni Giuseppe Vendramin
The article documents the public availability of RAD sequencing data and generated SNPs for the American mink (Neovison vison). 224,095 polymorphic loci were identified from 14 mink from which primers were designed for a subset of 380 SNPs. The panel was tested on 211 mink. Fisher’s F-statistics (Fis, FIT and FST) as well as observed (HO), expected (HE) and unbiased expected (uHE) heterozygosity was calculated for the SNPs and 194 SNPs was validated as being...
Sex chromosomes have evolved independently in phylogenetically diverse flowering plant lineages. The genes governing sex determination in dioecious species remain unknown, but theory predicts that the linkage of genes influencing male and female function will spur the origin and early evolution of sex chromosomes. For example, in an XY system, the origin of an active Y may be spurred by the linkage of female suppressing and male promoting genes. Garden asparagus (Asparagus officinalis) serves as...
Data from: Evidence of divergent selection for drought and cold tolerance at landscape and local scales in Abies alba Mill. in the French Mediterranean AlpsAnna M. Roschanski, Katalin Csilléry, Sascha Liepelt, Sylvie Oddou-Muratorio, Birgit Ziegenhagen, Frédéric Huard, Kristian K. Ullrich, Dragos Postolache, Giovanni G. Vendramin & Bruno Fady
Understanding local adaptation in forest trees is currently a key research and societal priority. Geographically and ecologically marginal populations provide ideal case studies, because environmental stress along with reduced gene flow can facilitate the establishment of locally adapted populations. We sampled European silver fir (Abies alba Mill.) trees in the French Mediterranean Alps, along the margin of its distribution range, from pairs of high and low elevation plots on four different mountains situated along a...
Data from: Local effects drive heterozygosity-fitness correlations in an outcrossing long-lived treeIsabel Rodriguez-Quilon, Luis Santos-Del-Blanco, Delphine Grivet, Juan Pablo Jaramillo-Correa, Juan Majada, Giovanni Vendramin, Ricardo Alía & Santiago Gonzalez-Martinez
Heterozygosity-fitness correlations (HFCs) have been used to understand the complex interactions between inbreeding, genetic diversity and evolution. Although frequently reported for decades, evidence for HFCs was often based on underpowered studies or inappropriate methods, and hence their underlying mechanisms are still under debate. Here, we used 6,100 genome-wide Single Nucleotide Polymorphisms (SNPs) to test for general and local effect HFCs in maritime pine (Pinus pinaster Ait.), an iconic Mediterranean forest tree. Survival was used as...
