Eucalypts are the world’s most widely planted hardwood trees. Their outstanding diversity, adaptability and growth have
made them a global renewable resource of fibre and energy. We sequenced and assembled >94% of the 640-megabase
genome of Eucalyptus grandis. Of 36,376 predicted protein-coding genes, 34% occur in tandem duplications, the largest...
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that...
Gramene is a comparative information resource for plants that integrates data across diverse data domains. In this article,
we describe the development of a quantitative trait loci (QTL) database and illustrate how it can be used to facilitate
both the forward and reverse genetics research. The QTL database contains the...

To address patterns of genetic connectivity in a mass-aggregating marine fish, we analyzed genetic variation in
mitochondrial DNA (mtDNA), microsatellites, and single nucleotide polymorphisms (SNPs) for Nassau grouper (Epinephelus
striatus). We expected Nassau grouper to exhibit genetic differentiation among its subpopulations due to its reproductive
behavior and retentive oceanographic conditions...

Plant pathogens secrete an arsenal of small secreted proteins (SSPs) acting as effectors that modulate host immunity to
facilitate infection. SSP-encoding genes are often located in particular genomic environments and show waves of concerted
expression at diverse stages of plant infection. To date, little is known about the regulation of...

Widespread habitat degradation and uncharacteristic fire, insect, and disease outbreaks in forests across
the western United States have led to highly publicized calls to increase the pace and scale of forest restoration.
Despite these calls, we frequently lack a comprehensive understanding of forest restoration
needs. In this study we demonstrate...

A new functional gene database, FOAM (Functional
Ontology Assignments for Metagenomes), was developed
to screen environmental metagenomic sequence
datasets. FOAM provides a new functional
ontology dedicated to classify gene functions relevant
to environmental microorganisms based on Hidden
Markov Models (HMMs). Sets of aligned protein
sequences (i.e. ‘profiles’) were tailored to...

in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) to similarly aged U.S. children
providing waking-hours waist-worn accelerometer data in the 2003-2006 National Health and Nutrition Examination

Meta-analyses of field studies have shown that biomass, density, species richness, and size of organisms protected by no-take marine reserves generally increase over time. The magnitude and timing of changes in these response variables, however, vary greatly and depend upon the taxonomic groups protected, size and type of reserve, oceanographic...

We investigated DNA methylomes of pediatric B-cell
acute lymphoblastic leukemias (B-ALLs) using
whole-genome bisulfite sequencing and high-definition
microarrays, along with RNA expression
profiles. Epigenetic alteration of B-ALLs occurred in
two tracks: de novo methylation of small functional
compartments and demethylation of large intercompartmental
backbones. The deviations were exaggerated
in lamina-associated...

Background
In the weeks following the first imported case of Ebola in the U. S. on September 29, 2014, coverage of the very limited outbreak dominated the news media, in a manner quite disproportionate to the actual threat to national public health; by the end of October, 2014, there were...

Anthropogenic and natural stressors often interact to affect organisms. Amphibian populations are undergoing unprecedented declines and extinctions with pesticides and emerging infectious diseases implicated as causal factors. Although these factors often co-occur, their effects on amphibians are usually examined in isolation. We hypothesized that exposure of larval and metamorphic amphibians...

As decomposers, fungi are key players in recycling plant material in global carbon cycles. We hypothesized that genomes of early diverging fungi may have inherited pectinases from an ancestral species that had been able to extract nutrients from pectin-containing land plants and their algal allies (Streptophytes). We aimed to infer,...

A feedback between decomposition and litter chemical composition occurs with decomposition altering composition that in turn influences the decomposition rate. Elucidating the temporal pattern of chemical composition is vital to understand this feedback, but the effects of plant species and climate on chemical changes remain poorly understood, especially over multiple...

Dysregulation of Sonic hedgehog (Shh) signaling has been implicated in glioma pathogenesis. Yet, the role of this pathway
in gliomagenesis remains controversial because of the lack of relevant animal models. Using the cytokeratin 5 promoter, we

Seascape ecology is an emerging discipline focused on understanding how features of the marine habitat influence the

In the future, Earth will be warmer, precipitation events will be more extreme, global mean sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes will also occur at an accelerated rate as developed areas increase in size and population density. We now...
