Nitrogen and light regulate symbiotic nitrogen fixation by a temperate forest tree
Symbiotic nitrogen fixation (SNF) is a critical mechanism of ecosystem recovery, and in forests of the eastern United States, the most common tree...
-
Staying hungry: a roadmap to harnessing central regulators of symbiotic nitrogen fixation under fluctuating nitrogen availability
Legumes have evolved specific inventions to enhance nitrogen (N) acquisition by establishing symbiotic interactions with N-fixing rhizobial bacteria....
-
What determines symbiotic nitrogen fixation efficiency in rhizobium: recent insights into Rhizobium leguminosarum
Symbiotic nitrogen fixation (SNF) by rhizobium, a Gram-negative soil bacterium, is an essential component in the nitrogen cycle and is a sustainable...
-
Symbiotic nitrogen fixation strategies relate to phenotypic plasticity but not invasion risk
Many invasive plant species are symbiotic N-fixers that can have strong impacts on ecosystem processes. Nitrogen-fixing plants use a diversity of...
-
Effect of drought stress on symbiotic nitrogen fixation, soil nitrogen availability and soil microbial diversity in forage legumes
Background and aimsForage legumes form mutualistic interactions with specialized soil rhizobia bacteria that inhabit root nodules and fix atmospheric...
-
Symbiotic and Asymbiotic Nitrogen Fixation: An Overview
Biological nitrogen fixationBiological nitrogen fixation (BNF) has evolved early during the evolution of life. Bacteria have nitrogenasenitrogenase...
-
Symbiotic nitrogen fixation does not stimulate soil phosphatase activity under temperate and tropical trees
Symbiotic nitrogen (N)-fixing plants can enrich ecosystems with N, which can alter the cycling and demand for other nutrients. Researchers have...

Identification of QTLs for symbiotic nitrogen fixation and related traits in a soybean recombinant inbred line population
Key messageThe genetic architecture of symbiotic N fixation and related traits was investigated in the field. QTLs were identified for percent N...
-
Bacterial consortia among Bradyrhizobium species, Azospirillum baldaniorum and Bacillus pumilus promote plant growth and efficient symbiotic nitrogen fixation in mung bean
The use of nitrogen-fixing bacteria in leguminous plants is a widespread approach, and the exploration of symbiotic bacteria that are efficient in...

Cold stress reduces nodulation and symbiotic nitrogen fixation in winter annual legume cover crops
AimsGrowers in northern U.S. regions rely on winter annual legume cover crop symbiotic nitrogen fixation (SNF) to reduce the need for spring...
-
Nitrogen but not phosphorus addition affects symbiotic N2 fixation by legumes in natural and semi-natural grasslands located on four continents
Background and aimsThe amount of nitrogen (N) derived from symbiotic N 2 fixation by legumes in grasslands might be affected by anthropogenic N and...
-
Effects of defoliation on root traits, nitrogen fixation, soil nitrogen availability, soil enzyme activities and soil bacterial communities of forage legumes
Background and AimsForage legumes fix atmospheric nitrogen through a mutualistic relationship with soil rhizobia bacteria. However, frequent...

Phosphorus Nutrition Enhancement of Biological Nitrogen Fixation in Pastures
Nitrogen (N) is the most limiting plant nutrient in agroecosystems. The increasing use of N-containing fertilizers increases greenhouse gas emissions...
-
Effect of symbiotic N2 fixation on leaf protein contents, protein degradation and nitrogen resorption during leaf senescence in temperate deciduous woody species
Nitrogen (N) resorption from senescing leaves enables plants to reuse N, making them less dependent on current N uptake from the environment, leading...
-
Nitrogen fixation capacity and metabolite responses to phosphorus in soybean nodules
Phosphorus (P) is necessary for nitrogen fixation in the root nodules of soybeans, a symbiotic process whereby plants support bacterial nitrogen...
-
Lotus japonicus regulates root nodulation and nitrogen fixation dependent on the molecular form of nitrogen fertilizer
PurposeLegumes form root nodules to gain fixed nitrogen from rhizobia and can also access nitrogen in soil. Data suggest that plants might...
-
Symbiotic Effectiveness of Rhizobium Strains in Agriculture
Symbiotic nitrogen fixation (SNF) by legumes plays major role in sustaining crop productivity of marginal lands and in small-holders systems. Farmers...
