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...

Abstract To improve our understanding of the organization and evolution wheat (Triticum aestivum) genome, we sequenced annotated 13-Mb contigs (18.2 Mb) originating from different regions its largest chromosome, 3B (1 Gb), produced a 2x chromosome survey by shotgun Illumina/Solexa sequencing. All carried genes irrespective their chromosomal location. However, gene distribution was not random, with 75% them clustered into small islands containing three on average. A twofold increase density...
Grapevine is one of the most economically important crops worldwide. However, previous versions grapevine reference genome tipically consist thousands fragments with missing centromeres and telomeres, limiting accessibility repetitive sequences, centromeric telomeric regions, study inheritance agronomic traits in these regions. Here, we assembled a telomere-to-telomere (T2T) gap-free for cultivar PN40024 using PacBio HiFi long reads. The T2T (PN_T2T) 69 Mb longer 9018 more genes identified...
The genome sequence of the diploid and highly homozygous Vitis vinifera genotype PN40024 serves as reference for many grapevine studies. Despite several improvements to assembly, its current version PN12X.v2 is quite fragmented only represents haploid state with mixed haplotypes. In fact, being nearly homozygous, this contains heterozygous regions that are yet be resolved. Taking opportunity long-read sequencing technologies offer fully discriminate haplotype sequences, an improved...
Abstract Studies were carried out on the grafting of acrylonitrile (AN) and acrylamide (AA) to starch by ceric ion. The variables affecting AN AA investigated with granular wheat dispersed in aqueous N , ‐dimethylformamide ammonium nitrate as catalyst. Results showed that concentrations monomer catalyst are major factors influencing AN; thus content grafts can be regulated these variables. is also influenced variables, but a much less degree. Increasing promote homopolymerization increasing...
A key step in domestication of the grapevine was transition from separate sexes (dioecy) wild Vitis vinifera ssp. sylvestris (V. sylvestris) to hermaphroditism cultivated sativa vinifera). It is known that V. has an XY system and a modified Y haplotype (Yh) sex locus small, but it not previously been precisely characterized.We generate high-quality de novo reference genome for sylvestris, onto which we map whole-genome re-sequencing data cross locate locus. Assembly full X, Y, Yh haplotypes...
Effective crop improvement, whether through selective breeding or biotech strategies, is largely dependent on the cumulative knowledge of a species' pangenome and its containing genes. Acquiring this specially challenging in grapevine, one oldest fruit crops grown worldwide, which known to have more than 30,000 Well-established research communities studying model organisms created maintained, public private funds, diverse range online tools databases serving as repositories genomes gene...
This study reports the first incursion into European poultry of H5N1 highly pathogenic notifiable avian influenza A (HPNAI) viruses from clade 2.3.2 that affected domestic and wild birds in Romania Bulgaria, respectively. Previous occurrences Europe HPNAI these populations have involved exclusively 2.2. represents most westerly spread viruses, which shown an apparently expanding range geographical dispersal since mid-2009 following confirmation infections waterfowl species Mongolia Eastern...
Abstract In an extensive screening program, 14 plant species have been identified which good potential as hydrocarbon‐ and rubber‐producing crops. These plants contain from 5 to 10% oil plus polymeric hydrocarbon on a dry weight basis. Since their matter yield should be 11,200 22,400 kg/ha/year, they would produce several times much conventional oilseed these plants, the is not concentrated in storage organs, i.e., seed or fruit tissue, but distributed throughout whole plant. Several are...
Abstract To improve our understanding of the organization and regulation wheat (Triticum aestivum) gene space, we established a transcription map chromosome (3B) by hybridizing newly developed expression microarray with bacterial artificial pools from new version 3B physical as well cDNA probes derived 15 RNA samples. Mapping data for almost 3,000 genes showed that space spans whole 2-fold increase density toward telomeres due to an in number islands. Comparative analyses rice (Oryza sativa)...
Although there are a number of bioinformatic tools to identify plant nucleotide-binding leucine-rich repeat (NLR) disease resistance genes based on conserved protein sequences, only few these have attempted that not been annotated in the genome. The overall goal NLGenomeSweeper pipeline is annotate NLR genes, including RPW8, genome assembly with high specificity and focus complete functional genes. This identification NB-ARC domain, most domain using BLAST suite. In this way, tool has for...
Abstract The grafting of acrylic acid (AAc) to starch was investigated with gamma‐pre‐irradiated and aqueous solutions AAc. rate increased initially time, then decreased, approached zero when the percentage reached a maximum value. At given radiation dose proportional first power concentration irradiated 1.5 initial Solvent effects on degree grafting, molecular weight, number grafted branches were evaluated. Higher degrees achieved electron‐irradiated at doses lower than those used gamma rays.
Summary Inducible plant defences against pathogens are stimulated by infections and comprise several classes of pathogenesis‐related (PR) proteins. Endo‐β‐1,3‐glucanases (EGases) belong to the PR‐2 class their expression is induced many pathogenic fungi oomycetes, suggesting that EGases play a role in hydrolysis pathogen cell walls. However, reports direct effect on walls scarce. Here, we characterized three from Vitis vinifera whose during infection Plasmopara viticola , causal agent downy...
Abstract Carotenoid levels in plant tissues depend on the relative rates of synthesis and degradation molecules pathway. While carotenoid biosynthesis has been extensively characterized, research catabolism into apocarotenoids is a relatively novel field. To identify apocarotenoid metabolic processes, we characterized transcriptome transgenic Arabidopsis (Arabidopsis thaliana) roots accumulating high β-carotene and, consequently, β-apocarotenoids. Transcriptome analysis revealed feedback...
A major aim in modern grapevine (Vitis vinifera L.) breeding programs is the introgression of disease resistance genes along with desired cultural and oenological traits. Understanding genetic links between agro-oenological traits a crucial issue for breeders. We studied determinism wide range complex interspecific hybrid population identified two cases colocalizations quantitative trait loci (QTL). The species origin chromosomal regions off-springs were determined thanks to silico...
The Oomycete Plasmopara viticola is responsible for downy mildew, which one of the most damaging grapevine diseases. Due to strictly biotrophic way life P. viticola, its metabolome relatively poorly characterized. In this work, we have used a mass spectrometry-based non-targeted metabolomic approach identify potential Plasmopara-specific metabolites. This has led characterization and structural elucidation compounds belonging three families atypical lipids, are not detected in healthy...
Downy mildew caused by the oomycete Plasmopara viticola is one of most important diseases affecting grapevine. Resistant varieties are an environmentally-friendly tool to control grapevine downy mildew. Efficient breeding for durable resistance requires knowledge underlying mechanisms. Here we aimed at identifying molecular basis Rpv2 , a gene extreme derived from Vitis rotundifolia and characterizing its effect on pathogen development. Individuals two populations segregating were evaluated...
