Characterization of the periplasmic redox network that sustains the versatile anaerobic metabolism of Shewanella oneidensis MR-1

Frontiers in Microbiology, 2015
The versatile anaerobic metabolism of the Gram-negative bacterium Shewanella oneidensis MR-1 (SOMR-1) relies on a multitude of redox proteins found in its periplasm.

Foliar Application of Nano‐Selenium Enhances Tea Quality and Selenium Biofortification by Promoting Theanine Synthesis and Nitrogen Metabolism

Plant Biotechnology Journal, EarlyView.
ABSTRACT Selenium (Se) biofortification improves crops' nutritional value, while nano‐selenium (nano‐Se) offers enhanced bioavailability over traditional Se fertilisers. The quality of tea (Camellia sinensis) depends critically on nitrogen (N) metabolism and amino acid balance, particularly of theanine.

Reprogramming of Gene Transcripts and Metabolites by the Wild Soybean Endophyte Pseudomonas sp. 77S3 Improves Soybean Salt Tolerance

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soybean is a critical source of protein and vegetable oil worldwide. Expanding its cultivation into salinity lands represents a promising strategy for increasing production; however, soil salinity severely limits soybean growth by disrupting physiological and metabolic homeostasis.

SERR Spectroelectrochemical Study of Cytochrome cd1 Nitrite Reductase Co-Immobilized with Physiological Redox Partner Cytochrome c552 on Biocompatible Metal Electrodes.

PLoS ONE, 2015
Cytochrome cd1 nitrite reductases (cd1NiRs) catalyze the one-electron reduction of nitrite to nitric oxide. Due to their catalytic reaction, cd1NiRs are regarded as promising components for biosensing, bioremediation and biotechnological applications ...

A functional description of CymA, an electron-transfer hub supporting anaerobic respiratory flexibility in Shewanella [PDF]

, 2012
CymA (tetrahaem cytochrome c) is a member of the NapC/NirT family of quinol dehydrogenases. Essential for the anaerobic respiratory flexibility of shewanellae, CymA transfers electrons from menaquinol to various dedicated systems for the reduction of ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

Plant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

The role of plant type and salinity in the selection for the denitrifying community structure in the rhizosphere of wetland vegetation [PDF]

, 2012
Coastal wetlands, as transient links from terrestrial to marine environments, are important for nitrogen removal by denitrification. Denitrification strongly depends on both the presence of emergent plants and the denitrifier communities selected by ...
