The as-yet uncultivated nitrogen-fixing cyanobacterium known as UCYN-A is widely distributed in the world's oceans. Metagenomic analysis has shown it to lack genes for the oxygen-producing ...

By partnering with soil microbes, nitrogen-fixing trees turn atmospheric nitrogen gas into a form of nitrogen that is available to plants. When fixers shed their leaves, they enrich soils with ...

How nitrogen fixing works . Before planting a cover crop, Gaskin said it helps to understand how legumes fix nitrogen into the soil. The bacteria with which legumes have a symbiotic — mutually ...

In two recent papers, an international team led by UC Santa Cruz scientists describe the first known nitrogen-fixing organelle within a eukaryotic cell. The organelle is the fourth example in history ...

Nitrogen-Fixing Nodules Evolved More Than Once in Plants. 4mo. Feeding the world's expanding population is made possible by ...

Nitrogen-fixing trees can fertilize the soil with the help of partner bacteria. It has remained a puzzle why these trees do not become more prevalent in nitrogen-poor tropical forests.

For example, legumes house nitrogen-fixing microbes in small nodules on their roots. However, these mutualisms only occur in a small number of plants and a scant number of crop species.

Humanity depends on nitrogen to fertilize croplands, but growing global use is damaging the environment and threatening human health. How can we chart a more sustainable path? Billions of people ...

Nitrogen-fixing bacteria are a crucial, if largely unknown, part of our ecosystem. They're how plants and animals get nitrogen from the air.

Unveiling the Nitroplast: A Game-Changing Nitrogen-Fixing Organelle. The researchers did not start out looking for a new organelle. Years ago, John Zehr, a marine microbiologist at the University of ...

However, there have been strains of Bradyrhizobium, a nitrogen fixing bacteria, that have been shown to not provide efficient amounts of nitrogen to the plant. “So, in a way, it’s almost acting in a ...
