Quantifying the Impact of Climate Change on Marine Diazotrophy: Insights From Earth System Models

open access: yesFrontiers in Marine Science, 2020
Nitrogen fixation is a major source of new nitrogen to the ocean, supporting biological productivity in the large nitrogen-limited tropical oceans. In Earth System Models, the response of nitrogen fixation to climate change acts in concert with projected

Role of Hydroxylamine in Biological Fixation of Nitrogen [PDF]

open access: yesNature, 1949
THE position of hydroxylamine as an intermediate in the nitrogen fixation process has become increasingly doubtful as a result of recent studies1,2. No direct attempts have been made, however, to find the effect of hydroxylamine on nitrogen fixation. An application of the isotope tracer method to this problem is being made in these laboratories, using ...

Relationships between biological nitrogen fixation and available nitrogen at scales from molecular to community level

open access: yes, 2017
In the context of the current rapid increase of anthropogenic nitrogen input in global ecosystems, clarifying the relationship between biological nitrogen fixation and available nitrogen has important guiding significance for the estimation of ecosystem ...

Biological nitrogen fixation in legumes

open access: yes, 2020
In nature, biological nitrogen fixation (BNF) provides most of the reactive nitrogen that is required for protein formation and plant growth. Legumes host BNF, so understanding BNF provides a foundation for many decisions made in legume cropping.This ...

Tracking Spatiotemporal Extracellular Matrix Evolution and Tissue Fusion in 3D Microtissues via Click Chemistry‐Based Metabolic Labelling

open access: yesAdvanced Healthcare Materials, EarlyView.
Metabolic labeling of nascent proteins in 3D microtissue spheroids provides a powerful analytical approach for large‐scale tissue engineering. Incorporation of non‐canonical amino acids with fluorescent tagging enables spatiotemporal investigation of extracellular matrix deposition and its evolution during multicellular tissue development and fusion ...

Lowering the Mo limit for nitrogen fixation by Mo-nitrogenase

open access: yesCommunications Earth & Environment
Archean ocean marine primary productivity may have been limited by biologically available nitrogen. Due to low molybdenum abundances, early biological nitrogen fixation is thought to have relied on alternative nitrogenases that incorporate vanadium or ...

Promoting black oat and ryegrass growth via Azospirillum brasilense inoculation after corn and soybean crop rotation [PDF]

open access: yesEmirates Journal of Food and Agriculture
Inadequate management of nitrogen fertilization, due to high costs, compromises the nutrition and productivity of winter forage plants, highlighting the need to adopt sustainable alternatives, such as using nitrogen-fixing bacteria.

Bedrock Nitrogen Weathering Stimulates Biological Nitrogen Fixation [PDF]

open access: yesThe Bulletin of the Ecological Society of America, 2019
AbstractGlobal ecosystem models suggest that bedrock nitrogen (N) weathering contributes 10–20% of total N inputs to the natural terrestrial biosphere and >38% of ecosystem N supplies in temperate forests specifically. Yet, the role of rock N weathering in shaping ecological processes and biogeochemical fluxes is largely unknown.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
