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...
Silver birch (Betula pendula) is a pioneer boreal tree that can be induced to flower within 1 year. Its rapid life cycle, small (440-Mb) genome, and advanced germplasm resources make an attractive model for forest biotechnology. We assembled chromosomally anchored the nuclear genome of inbred B. pendula individual. Gene duplicates from paleohexaploid event were enriched transcriptional regulation, whereas tandem overrepresented by environmental responses. Population resequencing 80...
The genus Populus consists of dioecious woody species with largely unknown genetic mechanisms for gender determination. We have discovered and genomic features in the peritelomeric region chromosome XIX that suggest this genome is process developing characteristics a sex chromosome. identified gender-associated locus consistently maps to region. Furthermore, comparison across multiple families reveals distorted segregation within intensively characterized using an F 1 interspecific cross...
Salix caprea is a cold-tolerant pioneer species that ecologically important in Europe and western central Asia. However, little data available on its population genetic structure molecular ecology. We describe the levels of geographic natural Irish populations S. determine extent gene flow sexual reproduction using both chloroplast nuclear simple sequence repeats (SSRs). A total 183 individuals from 21 semi-natural woodlands were collected genotyped. Gene diversity across was high for SSRs...
As part of a larger project to sequence the Populus genome and generate genomic resources for this emerging model tree, we constructed physical map genome, representing one few such maps an undomesticated, highly heterozygous plant species. The map, consisting 2802 contigs, was from fingerprinted bacterial artificial chromosome (BAC) clones. represents approximately 9.4-fold coverage which has been estimated assembly be 485 +/- 10 Mb in size. BAC ends were sequenced assist long-range...

• Background and Aims Populations of oak (Quercus petraea Q. robur) were investigated using morphological molecular (AFLP) analyses to assess species distinction. The study aimed describe distinction in Irish populations situate this a European context.
Abstract We have evaluated High Resolution Melting (HRM) analysis as a method for one‐step haplotype identification in phylogeographic analysis. Using two adjoined internal amplicons ( c . 360 and 390 bp) at the chloroplast rps16 intron 750 we applied HRM to identify haplotypes 21 populations of European arctic‐alpine herb species Arenaria ciliata norvegica (Caryophyllaceae). From 446 accessions studied, 20 composite were identified by melting‐curve protocol, 18 which could be uniquely. In...
Background and Aims Although hybridization can play a positive role in plant evolution, it has been shown that excessive unidirectional result replacement of species' gene pool, even the extinction rare species via genetic assimilation. This study examines levels introgression between common Saxifraga spathularis its rarer congener S. hirsuta, which have observed to hybridize wild where they occur sympatrically. Methods Seven species-specific single nucleotide polymorphisms (SNPs) were...
Summary This paper describes the route, speed and mode of colonisation oaks by integrating a number independent analyses using molecular ecology, palaeoecology simulation modelling approaches. Using synthetic map contemporary distribution chloroplast DNA (integrating several published unpublished data sets describing variation in 1468 trees from 313 autochthonous stands Q. robur petraea Britain Ireland), considering postglacial topographic landscape, most likely routes across British Isles...
Little is known about the levels of variation in lignin or other wood related genes Salix, a genus that being increasingly used for biomass and biofuel production. The biosynthesis pathway well characterized number species, including model tree Populus. We aimed to transfer genomic resources already available Populus its sister Salix assess within involved formation.Amplification trials 27 gene regions were undertaken 40 taxa. Twelve these sequenced. Alignment searches resulting sequences...
Despite constituting the western-most edge of population distributions for several native European plants, Ireland has largely been left out key Europe-wide phylogeographic studies. This is true birch (Betula pubescens Ehrh. and Betula pendula Roth), which genetic diversity yet to be mapped Ireland. Here we used eight cpDNA markers (two Restriction Fragment Length Polymorphism (RFLP) six Simple Sequence Repeat (SSR)) map B. pubescens, pendula, putative hybrid individuals sampled from 19...
In the version of this article initially published, there was a mistake in calculation nucleotide mutation rate per site generation: 1 × 10−9 mutations generation used, whereas 9.5 correct. This error affects interpretation population-size changes over time and their possible correspondence with known geological events, as shown original Fig. 4 supporting discussion text, well details Supplementary Note. Neither data themselves nor any other results are affected. Figure has been revised...
Picea sitchensis, Sitka spruce, is of interest to forestry as both a conservation species and highly productive crop. Its native range stretches from Alaska California, it hence distributed across large environmental cline with areas local adaptation. The IUFRO collection, established in 1968–1970, consists 81 provenances commercial scientific spanning this range. We used genotyping-by-sequencing on 1177 genotypes, originating 80 the which occupy 19 geographic regions Pacific Northwest,...
