Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Expression of nirK and nirS genes in two strains of Pseudomonas stutzeri harbouring both types of NO-forming nitrite reductases

, 2018
Reduction of nitrite to nitric oxide in denitrification is catalysed by two different nitrite reductases, encoded by nirS or nirK. Long considered mutually exclusive and functionally redundant in denitrifying bacteria, we show expression of both genes co-

Calcium, methyl jasmonate and their combined foliar applications: Influence on Tempranillo grape amino acids composition over two seasons

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change is currently affecting chemical grape composition and, consequently, grape quality. The foliar application of biostimulants has emerged as a promising approach to mitigate these effects. This study investigated the effects of foliar applications of calcium (Ca), methyl jasmonate (MeJ), and their combination (Ca + MeJ)

Investigating the biosynthesis of heam d1 in pseudomonas aeruginosa: a cofactor for dissimilatory nitrite reductase.

, 2010
PhDHaem d1 is a modified tetrapyrrole unique to the periplasmic enzyme nitrite reductase where it acts in catalysing the reduction of nitrite (NO2 -) to nitric oxide (NO), as part of denitrification.

Resolution of key roles for the distal pocket histidine in cytochrome c nitrite reductases

, 2015
Cytochrome c nitrite reductases perform a key step in the biogeochemical N-cycle by catalyzing the six-electron reduction of nitrite to ammonium. These multi-heme cytochromes contain a number of His/His ligated c-hemes for electron transfer and a ...

Proteomics of Nitrotyrosine: Integrating Mass Spectrometry and Immunodetection in Redox‐Driven Pathology

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.

Protein NirP1 regulates nitrite reductase and nitrite excretion in cyanobacteria

Nature Communications
Abstract When the supply of inorganic carbon is limiting, photosynthetic cyanobacteria excrete nitrite, a toxic intermediate in the ammonia assimilation pathway from nitrate. It has been hypothesized that the excreted nitrite represents excess nitrogen that cannot be further assimilated due to the missing carbon ...

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

Bacterial nitrate reductases: Molecular and biological aspects of nitrate reduction [PDF]

, 2006
Nitrogen is a vital component in living organisms as it participates in the making of essential biomolecules such as proteins, nucleic acids, etc. In the biosphere, nitrogen cycles between the oxidation states +V and -III producing many species that ...
