The marine nitrogen cycle is crucial to sustaining ocean productivity, with biological nitrogen fixation representing a primary mechanism by which inert atmospheric nitrogen is converted into ...

The regulation of the biological fixation of nitrogen in hydric stress conditions varies with the different species of legume plants studied. This was the conclusion of Ruben Ladrera Fernández in his ...

Climate warming can increase plant growth in permafrost regions by lengthening the growing season, speeding up plant ...

Heterocyst differentiation constitutes a pivotal developmental process in filamentous cyanobacteria, allowing these organisms to sidestep the oxygen sensitivity of the nitrogenase enzyme. Under ...

When we think of the atmosphere and its necessity in sustaining life, we are thinking of oxygen and for plants, carbon dioxide. There is another chemical, though, a clear, odorless and tasteless gas ...

A new research initiative led by associate professor of bacteriology Betül Kaçar is positioned to transform agriculture and address some of the world’s most pressing ecological and economic challenges ...

I was taken back a significant period of years by the article in C&EN on nitrogen fixation as a potential answer to the massive overuse of fertilizers (July 31, 2023, page 24). The underlying reasons ...

Fertilizers are one of the main reasons that we are able to grow enough crops to feed the almost 8 billion humans living on Earth. Modern agriculture depends largely on nitrogen-based fertilizers, ...

A new evaluation of biological nitrogen fixation for inland and coastal waters concludes that these habitats are an overlooked but important source of fixation globally. Robinson Fulweiler and ...

A typical day for Jieshun Lin began with a long bus ride to the greenhouses. “For 10 hours each day, I would pull up plants and wash their roots, looking carefully at each individual plant. [Up to] 10 ...

Ever wanted to produce nitrogen fertilizer like they did in the 1900s? In that case, you’re probably looking at the Birkeland-Eyde process, which was the first industrial-scale atmospheric nitrogen ...

Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found ...
