Stage‐Dependent Metabolic Reprogramming Drives a Self‐Organizing Microbial Network During Shanxi Aged Vinegar

Food Bioengineering, EarlyView.
Metabolic shifts from growth to stress adaptation in Shanxi aged vinegar fermentation link flavor maturation and microbial cooperation, and Lactobacillus and Acetobacter form a self‐organizing metabolic network through division of labor. ABSTRACT Acetic acid fermentation (AAF) is a vital stage in the production of Shanxi aged vinegar (SAV), during ...

Production of Nitric Oxide and Nitrosylleghemoglobin Complexes in Soybean Nodules in Response to Flooding

Molecular Plant-Microbe Interactions, 2010
Nitric oxide (NO) has gained interest as a major signaling molecule during plant development and in response to environmental cues. Formation of NO during symbiotic interactions has been reported, but the role and sources of NO in nodules remain unclear.

Nitrate Reductase Regulates Expression of Nitrite Uptake and Nitrite Reductase Activities in Chlamydomonas reinhardtii [PDF]

Plant Physiology, 1992
In Chlamydomonas reinhardtii mutants defective at the structural locus for nitrate reductase (nit-1) or at loci for biosynthesis of the molybdopterin cofactor (nit-3, nit-4, or nit-5 and nit-6), both nitrite uptake and nitrite reductase activities were repressed in ammonium-grown cells and expressed at high amounts in nitrogen-free media or in media ...

Genetic switch to lower nitrogen fertilizer dependency and enhance maize yield

iMetaOmics, EarlyView.
Transcription factor NCR1 regulates nitrate transporter NRT2.3 and controls root‐to‐shoot nitrogen transport. A superior NCR1 haplotype, lost in modern maize breeding, boosts this process. This discovery enables breeding and biotechnology to develop high‐yielding maize varieties that require less nitrogen fertilizer, reducing agricultural costs and ...

A novel mechanism for dissimilatory nitrate reduction to ammonium in Acididesulfobacillus acetoxydans

mSystems
The biological route of nitrate reduction has important implications for the bioavailability of nitrogen within ecosystems. Nitrate reduction via nitrite, either to ammonium (ammonification) or to nitrous oxide or dinitrogen (denitrification), determines

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

Comparative modelling and molecular docking of nitrate reductase from Bacillus weihenstephanensis (DS45)

Journal of Taibah University for Science, 2016
Nitrate reductase catalyses the oxidation of NAD(P)H and the reduction of nitrate to nitrite. NR serves as a central point for the integration of metabolic pathways by governing the flux of reduced nitrogen through several regulatory mechanisms in plants,

Bisphenol A and Its Analogs: Toxicity Analysis in Mouse and Rat Liver—A Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) and its analogs are widely recognized for their use in industry and plastic manufacturing. Consequently, humans and animals are continually exposed to various substances in their daily lives. This review evaluates the hepatic toxicity of BPA and its analogs in mice and rats, with particular emphasis on molecular mechanisms ...

Intra‐Plant Nitrogen Isotope Fractionation in Maize

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim The natural abundance of nitrogen isotopes (δ15N) provides a powerful integrative tracer of nitrogen uptake and assimilation in plants, yet the internal partitioning of δ15N among plant tissues remains insufficiently understood.
