We report the draft genome of black cottonwood tree, Populus trichocarpa . Integration shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction genome. More than 45,000 putative protein-coding genes were identified. Analysis assembled revealed a whole-genome duplication event; about 8000 pairs duplicated from that event survived in A second, older is indistinguishably coincident divergence and Arabidopsis lineages. Nucleotide substitution, tandem gene...

Flax (Linum usitatissimum) is an ancient crop that widely cultivated as a source of fiber, oil and medicinally relevant compounds. To accelerate improvement, we performed whole-genome shotgun sequencing the nuclear genome flax. Seven paired-end libraries ranging in size from 300 bp to 10 kb were sequenced using Illumina analyzer. A de novo assembly, comprised exclusively deep-coverage (approximately 94× raw, approximately 69× filtered) short-sequence reads (44-100 bp), produced set scaffolds...
Plann automates the process of annotating a plastome sequence in GenBank format for either downstream processing or submission by new based on similar, well-annotated plastome.Plann is Perl script to be executed command line. compares features annotated reference and then shifts intervals any matching locations plastome. Plann's output can used National Center Biotechnology Information's tbl2asn create Sequin file submission.Unlike Web-based annotation packages, locally executable that will...
Minimizing the impact of invasive alien species (IAS) on islands and elsewhere requires researchers to provide cogent information environmental socioeconomic consequences IAS public policy makers. Unfortunately, this has not been readily available owing a paucity scientific research failure community make their findings decision This review explores vulnerability biological invasion, reports impacts provides guidance technical resources that can help minimize effects in island ecosystems....
• Premise of study: To reliably identify lineages below the species level such as subspecies or varieties, we propose an extension to DNA‐barcoding using next‐generation sequencing produce whole organellar genomes and substantial nuclear ribosomal sequence. Because this method uses much longer versions traditional loci in plastid DNA, call our approach ultra‐barcoding (UBC). Methods: We used high‐throughput scan genome generate reliable sequence high copy number regions. Using method,...
Summary P opulus trichocarpa is widespread across western North America spanning extensive variation in photoperiod, growing season and climate. We investigated trait . using over 2000 trees from a common garden at V ancouver, C anada, representing replicate plantings of 461 genotypes originating 136 provenance localities. measured 40 traits encompassing phenological events, biomass accumulation, growth rates, leaf, isotope gas exchange‐based ecophysiology traits. With replicated 29 354...
Previous tribal classifications of Rhamnaceae have been based on fruit characters, resulting in the delimitation large and otherwise heterogeneous groups. We evaluated most recent classification with DNA sequences two regions plastid genome, rbcL trnL-F, from 42 genera representatives related families Elaeagnaceae, Barbeyaceae, Dirachmaceae, Urticaceae, Ulmaceae, Moraceae, Rosaceae. The trnL-F trees higher consistency retention indices than trees, patterns change are compared. closest...
Summary In order to uncover the genetic basis of phenotypic trait variation, we used 448 unrelated wild accessions black cottonwood ( Populus trichocarpa ) from much its range in western North America. Extensive data large‐scale phenotyping (with spatial and temporal replications within a common garden) genotyping 34 K single nucleotide polymorphism SNP array) all were for gene discovery genome‐wide association study GWAS ). We performed with 40 biomass, ecophysiology phenology traits 29 355...
An increasing number of plant-insect studies using phylogenetic analysis suggest that cospeciation events are rare in plant–insect systems. Instead, nonrandom patterns congruence produced by phylogenetically conserved host switching (to related plants) or tracking particular resources traits (e.g., chemical). The dominance many phytophagous insect groups may make the detection genuine difficult. One important test putative is to verify whether reciprocal speciation temporally plausible. We...

Abstract Ecotilling was used as a simple nucleotide polymorphism (SNP) discovery tool to examine DNA variation in natural populations of the western black cottonwood, Populus trichocarpa , and found be more efficient than sequencing for large‐scale studies genetic this tree. A publicly available, live reference collection P. from University British Columbia Botanical Garden study survey nine different genes among individuals 41 populations. large amount detected, but level appears less...
Inkjet micropatterning is a versatile deposition technique with broad applications in numerous fields. However, its application plant science largely unexplored. Leaf expansion one of the most important parameters field and many methods have been developed to examine differential rates different parts leaf lamina. Among them, based on tracking natural landmarks through digital imaging require complicated setup which must remain fixed under tension. Furthermore, resolution limited that...
Within papilionoid legumes, characterized by flowers with strong bilateral symmetry, a derived condition within angiosperms, Cadia ( purpurea ) has reverted to radially symmetrical flowers. Here, we investigate the genetic basis of this morphological reversal. Two orthologues floral symmetry gene CYCLOIDEA CYC demarcate adaxial (dorsal) region flower in typical legumes. In model legume Lotus japonicus , one these LegCYC genes been shown, like be required for establishment symmetry. This...
Abstract All species of the genus Populus (poplar, aspen) are dioecious, suggesting an ancient origin this trait. Despite some empirical counter examples, theory suggests that nonrecombining sex‐linked regions should quickly spread, eventually becoming heteromorphic chromosomes. In contrast, we show using whole‐genome scans sex‐associated region in trichocarpa is small and much younger than age genus. This indicates sex determination highly labile poplar, consistent with recent evidence...
Summary Establishing links between phenotypes and molecular variants is of central importance to accelerate genetic improvement economically important plant species. Our work represents the first genome‐wide association study inherently complex currently poorly understood architecture industrially relevant wood traits. Here, we employed an Illumina Infinium 34 K single nucleotide polymorphism ( SNP ) genotyping array that generated 29 233 high‐quality s in c . 3500 broad‐based candidate...
Willows (Salix: Salicaceae) form a major ecological component of Holarctic floras and consequently are an obvious target for DNA-based identification system. We surveyed two to seven plastid genome regions (~3.8 kb; ~3% the genome) from 71 Salix species across all five subgenera, assess their performance as DNA barcode markers. Although has relatively high level interspecific hybridization, this may not sufficiently explain near complete failure barcoding that we observed: only one had...
Populus trichocarpa is an ecologically important tree across western North America. We used a large population sample of 498 accessions over wide geographical area genotyped with 34K SNP array to quantify patterns genetic variation in this species (landscape genomics). present evidence that three processes contribute the observed patterns: (1) introgression from sister P. balsamifera, (2) isolation by distance (IBD), and (3) natural selection. Introgression was detected only at margins...
Summary As molecular phylogenetic analyses incorporate ever‐greater numbers of loci, cases cytonuclear discordance – the phenomenon in which nuclear gene trees deviate significantly from organellar are being reported more frequently. Plant examples topological discordance, caused by recent hybridization between extant species, well known. However, branch‐length less plants relative to animals. We use a combination de novo assembly and reference‐based mapping using short‐read shotgun...
