U.S. Geological Survey External Quality-Assurance Project Report for the National Atmospheric Deposition Program / National Trends Network and Mercury Deposition Network, 2011-12 [PDF]

open access: yes, 2014
The U.S. Geological Survey operated six distinct programs to provide external quality-assurance monitoring for the National Atmospheric Deposition Program (NADP) / National Trends Network (NTN) and Mercury Deposition Network (MDN) during 2011–2012.

The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

open access: yesMolecular Ecology, EarlyView.
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...

Elucidating the role of shikimate dehydrogenase in controlling the production of anthocyanins and hydrolysable tannins in the outer peels of pomegranate. [PDF]

open access: yes, 2019
BACKGROUND:The outer peels of pomegranate (Punica granatum L.) possess two groups of polyphenols that have health beneficial properties: anthocyanins (ATs, which also affect peel color); and hydrolysable tannins (HTs).

A guide to understanding and measuring photosynthetic induction: considerations and recommendations

open access: yesNew Phytologist, EarlyView.
Summary Photosynthetic induction is the leaf‐level process by which a plant assimilates CO2 from the atmosphere once exposed to a change in light intensity after a period of darkness or shade. In the field, photosynthetic induction can take place hundreds of times in a single day in response to rapid fluctuations in the light environment due to cloud ...

Microbiome and Metaproteome of Craniofacial Implant Regions in Health and Disease

open access: yesOral Diseases, EarlyView.
ABSTRACT Background Craniofacial defects from cancer surgery led to functional, aesthetic, and psychological challenges. Rehabilitation with craniofacial implants addresses these issues by improving prosthesis retention through osseointegration and providing predictable cosmetic results. However, maintaining a healthy transcutaneous region is essential

Metabolic engineering of stomatal precursor cells enhances photosynthetic water‐use efficiency and vegetative growth under water‐deficit conditions in Arabidopsis thaliana

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Stomata are epidermal pores that control the exchange of gaseous CO2 and H2O between plants and their environment. Modulating stomatal density can alter this exchange and thus presents a viable target for engineering improved crop productivity and climate resilience.

Quantitative constraint-based computational model of tumor-to-stroma coupling via lactate shuttle

open access: yes, 2015
Cancer cells utilize large amounts of ATP to sustain growth, relying primarily on non-oxidative, fermentative pathways for its production. In many types of cancers this leads, even in the presence of oxygen, to the secretion of carbon equivalents ...

Comparative proteomics analysis of root and nodule mitochondria of soybean

open access: yesPlant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Nitrogen deposition onto the United States and Western Europe: A synthesis of observations and models. [PDF]

open access: yes, 2005
The documented acceleration of NH3 and NOx (NO + NO2) emissions over the last 150 years has accelerated N deposition, compromising air and water quality and altering the functioning of terrestrial and aquatic ecosystems worldwide.
