Bacterial mutualists can modulate the biochemical capacity of animals. Highly coevolved nutritional mutualists do this by synthesizing nutrients missing from the host’s diet. Genomics tools have advanced the study of these partnerships. Here we examined the endosymbiont Xiphinematobacter (phylum Verrucomicrobia) from the dagger nematode Xiphinema americanum, a migratory ectoparasite of...

Nanotechnology is of increasing significance. Curation of nanomaterial data into electronic databases offers opportunities to better understand and predict nanomaterials’ behaviour. This supports innovation in, and regulation of, nanotechnology. It is commonly understood that curated data need to be sufficiently complete and of sufficient quality to serve their intended purpose....

Vitamin E improved liver histology in children and adults with NAFLD who participated in TONIC and PIVENS clinical trials,
but with significant inter-individual variability in its efficacy. Cytochrome P450 4F2 (CYP4F2) is the major enzyme
metabolizing Vit E, with two common genetic variants (V433M, rs2108622 and W12G, rs3093105) found to...

Pseudomonas protegens strain Pf-5 is a rhizosphere bacterium that suppresses soilborne plant diseases and produces at least seven different secondary metabolites with antifungal properties. We derived mutants of Pf-5 with single and multiple mutations in biosynthesis genes for seven antifungal metabolites: 2,4-diacetylphoroglucinol (DAPG), pyrrolnitrin, pyoluteorin, hydrogen cyanide, rhizoxin, orfamide A,...

Bioaccessibility in vitro tests measure the solubility of materials in surrogate biofluids. However, the lack
of uniform methods and the effects of variable test parameters on material solubility limit interpretation.
One aim of this study was to measure and compare bioaccessibility of selected economically important
alloys and metals in surrogate...

The impact of recent severe droughts throughout the United States, the potential for climate change to intensify the frequency and severity of drought, and discussion about the future of government assistance in agriculture highlight the need for a transition from drought as ‘disaster’ to drought as ‘managed risk’. However, guidance...

BACKGROUND: Basic leucine zipper (bZIP) transcription factors are present exclusively in eukaryotes and constitute
one of the largest and most diverse transcription factor families. The proteins are responsible for central
developmental and physiological processes in plants, animals, and fungi, including the pathogenicity of fungal
plant pathogens. However, there is limited...

We describe the use of linked land-use and forest sector models to simulate the effects of carbon offset sales on private forest owners' land-use and forest management decisions in western Oregon (USA). Our work focuses on forest management decisions rather than afforestation, allows full forest sector price adjustment to land-use...
