Original Source: How close are we to nitrogen-fixing cereals?
Engineering nitrogen-fixing cereals is essential for sustainable food production for the projected global population of 9 billion people in 2050. This process will require engineering cereals for nodule organogenesis and infection by nitrogen-fixing bacteria. The symbiosis signalling pathway is essential to establish both bacterial infection and nodule organogenesis in legumes and is also necessary for the establishment of mycorrhizal colonisation. Hence this signalling pathway is also present in cereals an...

Unusual symbiosis found between algae and nitrogen-fixing bacteria
Emerging from the investigation of a mysterious nitrogen-fixing microbe that has a very small genome, an international team of investigators has found that certain type of photosynthetic bacteria not...
Nitrogen fixation anniversary: Modern agriculture needs to use fertilizer more efficiently
"Consider Carl Bosch our leading candidate for a modern Prometheus. This year marks a century since Bosch, a chemist, opened the Oppau, Germany-based Stickstoffwerke (“nitrogen works”)—the first...
Oceanography: The trouble with the bubble
Past studies have suggested that the ocean's nitrogen budget has a deficit of fixed nitrogen. This view may now change, thanks to upward revisions of the rate of nitrogen input through biological acti...
New carbon accounting method to reduce nitrogen fertilizer use
In 2011, corn was planted on more than 92 million acres in the U.S. Because corn is a nitrogen-loving plant, farmers must use synthetic nitrogen fertilizer to their fields every year to achieve the...
Biogeochemistry: The depths of nitrogen cycling
Breakdown of dissolved organic nitrogen in the ocean had been thought to be the preserve of microbes at the surface. The discovery that these microbes are not up to the task calls for a reassessment o...
Global nitrogen availability consistent for past 500 years, linked to carbon levels
(Kansas State University) Despite humans increasing nitrogen production through industrialization, nitrogen availability in many ecosystems has remained steady for the past 500 years.
Nitrogen has key role in estimating CO2 emissions from land use change
(University of Illinois at Urbana-Champaign) A new global-scale modeling study that takes into account nitrogen -- a key nutrient for plants -- estimates that carbon emissions from human activities on...
Doubling of marine dinitrogen-fixation rates based on direct measurements
Biological dinitrogen fixation provides the largest input of nitrogen to the oceans, therefore exerting important control on the ocean's nitrogen inventory and primary productivity. Nitrogen-isotope d...

Effects of three different PAHs on nitrogen-fixing bacterial diversity in mangrove sediment.
Polycyclic aromatic hydrocarbons (PAHs) are of great environmental and human health concerns due to their widespread occurrence, persistence and carcinogenic properties. There is now compelling eviden...
An experiment was conducted under laboratory conditions to investigate the effect of two systemic herbicides viz., pendimethalin and quizalofop, at their recommended field rates (1.0 kg and 50 g act...
Active nitrogen-fixing heterotrophic bacteria at and below the chemocline of the central Baltic Sea.
The Baltic Sea receives large nitrogen inputs by diazotrophic (N2-fixing) heterocystous cyanobacteria but the significance of heterotrophic N2 fixation has not been studied. Here, the diversity, abund...
BACKGROUND: Symbiotic nitrogen (N)-fixing trees are rare in late-successional temperate forests, even though these forests are often N limited. Two hypotheses could explain this paradox. The 'phylogen...
