Wood is the most important natural and endlessly renewable source of energy therefore has a major future role as an environmentally cost-effective alternative to burning fossils fuels.The wood not only provision but also energy-sufficient material for our buildings many other products.In addition, developing cells represent one sinks excess atmospheric CO 2 , thereby reducing contributors global warming. WOOD IS ALSO A RAW MATERIAL FOR MAJOR GLOBAL INDUSTRY, AND ITS DEMAND INCREASINGWood...
Abstract The dataset presented here was collected by the GenTree project (EU-Horizon 2020), which aims to improve use of forest genetic resources across Europe better understanding how trees adapt their local environment. This individual tree-core characteristics including ring-width series and whole-core wood density for seven ecologically economically important European tree species: silver birch ( Betula pendula ), beech Fagus sylvatica Norway spruce Picea abies black poplar Populus nigra...
Oaks are an important part of our natural and cultural heritage. Not only they ubiquitous in most common landscapes1 but have also supplied human societies with invaluable services, including food shelter, since prehistoric times2. With 450 species spread throughout Asia, Europe America3, oaks constitute a critical global renewable resource. The longevity (several hundred years) probably underlies their emblematic historical importance. Such long-lived sessile organisms must persist the face...
Summary The tree of life is highly reticulate, with the history population divergence emerging from populations gene phylogenies that reflect histories introgression, lineage sorting and divergence. In this study, we investigate global patterns oak diversity test hypothesis there are regions genome broadly informative about phylogeny. We utilize fossil data restriction‐site associated DNA sequencing ( RAD ‐seq) for 632 individuals representing nearly 250 Quercus species to infer a...
Latitudinal and elevational gradients provide valuable experimental settings for studies of the potential impact global warming on forest tree species. The availability long-term phenological surveys in common garden experiments traits associated with climate, such as bud flushing sessile oaks (Quercus petraea), an ideal opportunity to investigate this impact. We sequenced 18 oak populations used available sequencing data three other closely related European white species pyrenaica, Quercus...
The importance of natural selection for shaping adaptive trait differentiation among populations allogamous tree species has long been recognized. Determining the molecular basis local adaptation remains largely unresolved, and respective roles demography in population structure are actively debated. Using a multilocus scan that aims to detect outliers from simulated neutral expectations, we analyzed patterns nucleotide diversity genetic at 11 polymorphic candidate genes drought stress...
Abstract Background Expressed Sequence Tags (ESTs) are a source of simple sequence repeats (SSRs) that can be used to develop molecular markers for genetic studies. The availability ESTs Quercus robur and petraea provided unique opportunity microsatellite accelerate research aimed at studying adaptation these long-lived species their environment. As first step toward the construction SSR-based linkage map oak quantitative trait locus (QTL) mapping, we describe mining survey EST-SSRs as well...
Summary Resistance to cavitation is a major determinant of plant survival under severe drought and can be used quantify species adaptive potential. Interspecific variation in this key trait well defined woody species, but intraspecific (level structure) resulting from standing genetic phenotypic plasticity has never been determined. Combining for the first time situ characterization natural populations two reciprocal common gardens dry wet sites, we estimated variance components (phenotypic,...
Poplar is the first forest tree genome to be decoded. As an initial step comprehensive analysis of poplar proteome, we described reference 2-D-maps for eight tissues/organs plant, and functional characterization some proteins. A total 398 proteins were excised from gels. About 91.2% identified by nanospray LC-MS/MS, based on comparison with 260 000 Populus sp. ESTs. In comparison, reliable PMFs obtained only 51% spots MALDI-TOF-MS, which 43% (83 spots) positively matched gene models...
Abstract Summary: Consensus genetic maps constructed from multiple populations are an important resource for both basic and applied research, including genome-wide association analysis, genome sequence assembly studies of evolution. The LPmerge software uses linear programming to efficiently minimize the mean absolute error between consensus map linkage each population. This minimization is performed subject inequality constraints that ensure ordering markers in preserved. When marker order...
Background Cavitation resistance to water stress-induced embolism determines plant survival during drought. This adaptive trait has been described as highly variable in a wide range of tree species, but little is known about the extent genetic and phenotypic variability within species. information essential our understanding evolutionary forces that have shaped this trait, for evaluation its inclusion breeding programs. Methodology We assessed cavitation (P50), growth carbon isotope...
Abstract Some 1339 trees from 48 Pinus pinaster stands were characterized by five chloroplast microsatellites, detecting a total of 103 distinct haplotypes. Frequencies for the 16 most abundant haplotypes ( p k > 0.01) spatially interpolated over lattice made 430 grid points. Fitting values on raw haplotype frequencies at same geographical location was tested regression analysis. A range‐wide ‘diversity map’ based allowed identification one ‘hotspot’ diversity in central and southeastern...
Abstract The 1.5 Gbp/2C genome of pedunculate oak ( Quercus robur ) has been sequenced. A strategy was established for dealing with the challenges imposed by sequencing such a large, complex and highly heterozygous whole‐genome shotgun WGS approach, without use costly time‐consuming methods, as fosmid or BAC clone‐based hierarchical methods. combined short long reads. Over 49 million reads provided Roche 454 GS ‐ FLX technology were assembled into contigs shorter Illumina sequence from...

The a large plant family comprising more than 900 species belonging to 8–10 genera. Using wide range molecular markers, population genetics gene diversity surveys were focus many studies during past 20 years. This work set stage for investigations genomics beginning early 1990s facilitated application genetic quantitative trait loci mapping...
Forest trees are an unparalleled group of organisms in their combined ecological, economic and societal importance. With widespread distributions, predominantly random mating systems large population sizes, most tree species harbour extensive genetic variation both within among populations. At the same time, demographic processes associated with Pleistocene climate oscillations land‐use change have affected contemporary range‐wide diversity may impinge on potential for future adaptation....

Genomic selection (GS) is a promising approach for decreasing breeding cycle length in forest trees. Assessment of progeny performance and the prediction accuracy GS models over generations therefore key issue. A reference population maritime pine (Pinus pinaster) with an estimated effective inbreeding size (status number) 25 was first selected simulated data. This (n = 818) covered three (G0, G1 G2) genotyped 4436 single-nucleotide polymorphism (SNP) markers. We evaluated effects on both...
