The Genome of Black Cottonwood, Populus trichocarpa (Torr. & Gray)
Analyzing the draft genome of the black cottonwood tree, Populus trichocarpa, revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. Expand
Bird-pollinated flowers in an evolutionary and molecular context.
The strong convergent evolution evident in bird-pollinated flowers raises a question about the nature of the genetic mechanisms underlying such transitions and whether the same gene systems are involved in most cases. Expand
Genome resequencing reveals multiscale geographic structure and extensive linkage disequilibrium in the forest tree Populus trichocarpa.
The results suggest that genetic drift has played a significant role in the recent evolutionary history of P. trichocarpa and suggests that genome-wide association studies and genomic selection in undomesticated populations may be more feasible in Populus than previously assumed. Expand
Use of Ecotilling as an efficient SNP discovery tool to survey genetic variation in wild populations of Populus trichocarpa
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 was found to be… Expand

Results show that de novo assembly, based solely on whole-genome shotgun short-sequence reads, is an efficient means of obtaining nearly complete genome sequence information for some plant species. Expand
A phylogenetic analysis of Rhamnaceae using rbcL and trnL-F plastid DNA sequences.
The plastid trees support the monophyly of the Rhamnaceae family and provide the basis for a new tribal classification, and three strongly supported clades are identified but morphological characters could not be found to underpin a formal taxonomic description of these three clades as subfamilies.

Rapid and recent origin of species richness in the Cape flora of South Africa
The results indicate that diversification began approximately 7–8 Myr ago, coincident with extensive aridification caused by changes in ocean currents, and shows that large continental bursts of speciation can occur rapidly over timescales comparable to those previously associated with oceanic island radiations.

Geographical and environmental gradients shape phenotypic trait variation and genetic structure in Populus trichocarpa.
Robust relationships between traits, population structure and geoclimate in P. trichocarpa reflect patterns which suggest that range-wide geographical and environment gradients have shaped its genotypic and phenotypic variability. Expand
Ecological and socioeconomic impacts of invasive alien species in island ecosystems
Minimizing the impact of invasive alien species (IAS) on islands and elsewhere requires researchers to provide cogent information on the environmental and socioeconomic consequences of IAS to the… Expand
Plann: A command-line application for annotating plastome sequences1
Unlike Web-based annotation packages, Plann is a locally executable script that will accurately annotate a plastome sequence to a locally specified reference plastom, ready to use in other software pipelines and can be easily rerun as a draft plastsome is improved. Expand
