Effect of Storage Temperature on the Quality and Nitrite Metabolism Mechanism of Rape [PDF]

open access: yesShipin Kexue
This study explored the effects of different storage temperatures (0, 10 and 25 ℃) on the nutritional quality, senescence-related physiological indicators (color, mass loss rate, soluble sugar, vitamin C (VC) and chlorophyll) and safety indicators ...

Plant responses to iron nutrition with emphasis on the underutilized crop tef (Eragrostis tef): A review

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803

open access: yesThe FEBS Journal, EarlyView.
Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I

Redox Reactivity of Nonsymbiotic Phytoglobins towards Nitrite

open access: yesMolecules
Nonsymbiotic phytoglobins (nsHbs) are a diverse superfamily of hemoproteins grouped into three different classes (1, 2, and 3) based on their sequences.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

open access: yesJournal 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

open access: yesNew 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 ...

Thaumarchaeal ammonium oxidation and evidence for a nitrogen cycle in a subsurface radioactive thermal spring in the Austrian Central Alps

open access: yesFrontiers in Microbiology, 2014
Previous studies had suggested the presence of ammonium oxidizing Thaumarchaeota as well as nitrite oxidizing Bacteria in the subsurface spring called Franz Josef Quelle (FJQ), a slightly radioactive thermal mineral spring with a temperature of 43.6 ...

Insights into plant‐part‐specific N2O production in roots and shoots of chicory (Cichorium intybus) using stable isotope labelling

open access: yesNew Phytologist, EarlyView.
Conceptual scheme of the nitrous oxide (N2O) production, consumption, and transport processes across the soil–plant–atmosphere continuum. Summary Nitrous oxide (N2O) contributes substantially to climate change and stratospheric ozone degradation, yet large uncertainties in its global budget point to overlooked sources.
