Effects of FACE on denitrification activity in paddy-field soil

浙江大学学报. 农业与生命科学版, 2007
A free-air CO2 enrichment (FACE) experiment was used to investigate the effects of elevated atmospheric CO2 concentration on soil denitrification activities. The FACE system was conducted under a rice/wheat rotation at Jiangdu, China.

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

New Phytologist, EarlyView.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

A QM/MM Study of Nitrite Binding Modes in a Three-Domain Heme-Cu Nitrite Reductase

Molecules, 2018
Copper-containing nitrite reductases (CuNiRs) play a key role in the global nitrogen cycle by reducing nitrite (NO2−) to nitric oxide, a reaction that involves one electron and two protons.

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

Plant, Cell &Environment, EarlyView.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.

Systems‐Level Plant Responses Reveal Pseudomonas‐Mediated Growth Promotion in Brachypodium Under Nitrogen Limitation

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant growth–promoting bacteria can enhance plant performance under nutrient limitation, yet the underlying plant molecular responses remain incompletely resolved. We investigated growth promotion by Pseudomonas koreensis in Brachypodium distachyon under contrasting nitrogen (N) regimes using time‐resolved phenotyping, elemental analysis ...

Analysis of Microbial Diversity Dominating Nitrite Enzymatic Degradation and Acidic Degradation in the Fermentation Broth of Northeast Sauerkraut

Foods
Nitrite hazard is an important food safety issue in the production process of Chinese Northeastern sauerkraut, but this nitrite can be eliminated through microbial enzymatic degradation and acidic degradation as fermentation progresses.
