• 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,...
Abstract Understanding evolutionary relationships in the superfamily Psylloidea is challenging due to lack of clear morphological synapomorphies for many groups. Some families and genera, including two largest, Cacopsylla Ossiannilsson Trioza Foerster, have long been acknowledged as nonmonophyletic circumscription natural groups has remained fluid. We present best phylogenetic hypothesis date provide a working systematic framework better reflect relationships. A shotgun sequencing approach...
Understanding local adaptation has become a key research area given the ongoing climate challenge and concomitant requirement to conserve genetic resources. Perennial plants, such as forest trees, are good models study their wide geographic distribution, largely outcrossing mating systems, demographic histories. We evaluated signatures of in European aspen (Populus tremula) across Europe by means whole-genome resequencing collection 411 individual trees. dissected admixture patterns between...
Cultivated flax (Linum usitatissimum) is known to have undergone a whole-genome duplication around 5–9 million years ago. The aim of this study was investigate whether other events occurred in the evolutionary history cultivated flax. Knowledge such duplications will be important understanding biology and genomics Transcriptomes 11 Linum species were sequenced using Illumina platform. short reads assembled de novo DupPipe pipeline used look for signatures polyploidy from age distribution...
Some clover species, particularly Trifolium subterraneum, have previously been reported to highly unusual plastomes, relative closely related legumes, enlarged with many duplications, gene losses and the presence of DNA unique Trifolium, which may represent horizontal transfer. In order pinpoint evolutionary origin this phenomenon within genus we sequenced assembled plastomes eight additional species widely sampled from across genus.The fell into two groups: those boissieri, T. strictum...
Atlantic herring Clupea harengus feeding in the Norwegian Sea are assumed to consist of spring spawners (NSSH), Icelandic summer (ISSH) and North autumn (NSAH). Putative (NASH), Faroese (FASH) (FSSH) also feed area. However, until there is a method discriminate between populations mixed samples, fishery survey data from will be solely attributed predominating NSSH, ultimately causing biased stock assessments. Hence, we evaluated if panel 120 single nucleotide polymorphisms (SNPs) associated...
Transposable elements (TEs) and other repetitive are a large dynamically evolving part of eukaryotic genomes, especially in plants where they can account for significant proportion genome size. Their dynamic nature gives them the potential use identifying characterizing crop germplasm. However, their makes challenging to study using conventional methods molecular biology. Next generation sequencing new computational tools have greatly facilitated investigation TE variation within species...
Summary The plastid genome retains several features from its cyanobacterial-like ancestor, one being the co-transcriptional organization of genes into operon-like structures. Some operons have been identified but undoubtedly many more remain undiscovered. Here we utilize highly variable plastome structure that exists within certain legumes inverted repeat lost clade (IRLC) to find conserved gene clusters. These plastomes exhibit an unusually high frequency translocations and inversions. We...
The genus Leymus (lymegrass) comprises about 30 polyploid, perennial, temperate grass species in the tribe Triticeae (family Poaceae). Previous studies indicated a large diversity genome, and therefore, aim of this study was to isolate new repetitive DNA sequences that can be used for differentiating elucidating their genomic relationships. A C 0 t-1 plasmid library generated from American tetraploid triticoides . family highly satellite sequences, designated Lt1, obtained library. Lt1...
Genome-Wide Association Studies (GWAS) of four Multi-parent Advanced Generation Inter-Cross (MAGIC) populations identified nine regions on chromosomes 1H, 3H, 4H, 5H, 6H and 7H associated with resistance against barley scald disease. Three these are putatively novel Quantitative Trait Loci (QTL). Barley is caused by Rhynchosporium commune, one the most important leaf diseases that prevalent in barley-growing regions. Up to 40% yield losses can occur susceptible cultivars. Four MAGIC were...
Although grass dominates most agricultural systems in the North Atlantic region (NAR), spring barley is important cereal and used for animal feed food drink products. Recent changes climate have resulted warmer conditions across NAR which major implications crop production. In this paper, we investigate thermal requirement of use results to examine effects recent trends temperature rainfall on cultivation, based 11 regional meteorological sites. At these sites, between 1975 2015, found...
Abstract The impacts of climate change on marine ecosystems can be seen in the changing distribution, migration, and abundance species oceans. For some this environment may beneficial support population expansions. In northeast Atlantic (NEA), mackerel (Scomber scombrus) is undergoing an increase stock size accompanied by summer migration patterns, which have resulted expansion further north west than previously recorded. This study uses microsatellite loci to confirm differentiation among...
Abstract Understanding the genetic differentiation among populations of most marine fish requires investigating differences spawning grounds. However, this can be challenging as grounds for some species are not well known, or difficult to collect. An alternative is collect juvenile in nursery habitats closely associated with potential Greenland halibut a deep-dwelling, commercially important at least two identified major offshore North Atlantic and weak across Atlantic. In study, we sampled...
Lumpfish is now the single most important cleaner fish species to date and there an extensive lumpfish translocation along Norwegian coast. A reliable baseline information about population genetic structure of a prerequisite for optimal managing minimize possible avoid hybridisation introgression with local populations. The current study follow up Jónsdóttir et al. (2018) using expressed sequence tag-short tandem repeats (EST-STRs) markers. Samples (N = 291) were analysed from six sample...
In recent years the number of non-indigenous marine species has been increasing in Icelandic waters.In May 2019, a razor shell (Ensis sp.) was found for first time Iceland.Since then, living and empty shells have discovered at several locations Southwest Iceland.Upon morphological examination, specimens were thought to belong either Ensis leei or terranovensis, both native east coast North America.Molecular analysis, using COI 16S rRNA markers, showed that latter species.Native populations...
Abstract Capelin ( Mallotus villosus ) is both an important commercial and ecological resource of the North Atlantic subpolar region. Two decades ago, stock distribution around Iceland drastically changed. During autumn, which corresponds to main feeding period, capelin was previously located between Jan Mayen area. Since beginning 2000s, aggregation has been at east coast Greenland, inducing slight changes in timing route spawning migration along Icelandic shelf, therefore catches. Changes...
Abstract Transnational cooperation is a common strategy for addressing research and development (R&D) issues resulting from similar challenges that cut across administrative borders. Value chains food drinks are complex, transdisciplinary work recognised as method solving complex issues. The Northern Cereals project ran 2015 to 2018, its goal was increase cereal production the value of grain products in four regions Periphery programme area. included both R&D, but main emphasis on...
Sidalcea is a genus of flowering plants restricted to the west coast North America, commonly known as checkermallows. Remarkably, ~ 30 recognized species, 16 are conservation concern (vulnerable, imperilled or critically imperilled). To facilitate biological studies in this genus, and wider Malvaceae, we have sequenced whole plastid genome hendersonii. This will allow us both check those regions already developed general Malvaceae markers previous study, search for new regions. By comparing...
