The filamentous fungus Neurospora crassa responds to light in complex ways. To thoroughly
study the transcriptional response of this organism to light, RNA-seq was used to analyze capped and
polyadenylated mRNA prepared from mycelium grown for 24 hr in the dark and then exposed to light for
0 (control) 15,...

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...
Fungal hyphae are among the most highly polarized cells. Hyphal polarized
growth is supported by tip-directed transport of secretory vesicles, which accumulate temporarily
in a stratified manner in an apical vesicle cluster, the Spitzenkörper. The exocyst complex
is required for tethering of secretory vesicles to the apical plasma membrane. We...

We present genetic and morphological evidence supporting the recognition of a
previously synonymized species of Mesoplodon beaked whale in the tropical Indo-Pacific,
Mesoplodon hotaula. Although the new species is closely-related to the rare
ginkgo-toothed beaked whale M. ginkgodens, we show that these two lineages can be
differentiated by maternally (mitochondrial...

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...

Context:
Functional connectivity—the facilitation of individual movements among habitat patches—is essential for species’ persistence in fragmented landscapes. Evaluating functional connectivity is critical for predicting range shifts, developing conservation plans, and anticipating effects of disturbance, especially for species affected by climate change.
Objectives:
We examined whether simplifying forest structure influenced animal...

Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmental and maternal milieu become favorable for pregnancy to progress. We found that uterine Msx expression persists...

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 eukaryotes, ARGONAUTE proteins (AGOs) associate with microRNAs (miRNAs), short
interfering RNAs (siRNAs), and other classes of small RNAs to regulate target RNA or target
loci. Viral infection in plants induces a potent and highly specific antiviral RNA silencing
response characterized by the formation of virus-derived siRNAs. Arabidopsis thaliana has...

Non-structural carbohydrates (NSC) in plant tissue are frequently quantified to make inferences about plant responses to environmental conditions. Laboratories publishing estimates of NSC of woody plants use many different methods to evaluate NSC. We asked whether NSC estimates in the recent literature could be quantitatively compared among studies. We also...
