What to know about Nitrogen-fixing genes moved into new bacterial strains, opening path beyond fertilizer

Researchers from Washington State University have developed a method to transfer nitrogen-fixing gene clusters from rhizobia bacteria into other bacterial strains. This proof-of-concept study aims to eventually engineer microbes in major crops to harvest nitrogen from the atmosphere, potentially reducing the need for chemical fertilizers.

What happened

Nitrogen-fixing genes moved into new bacterial strains, opening path beyond fertilizer Gaby Clark Scientific Editor Robert Egan Associate Editor Most major crops, such as wheat and corn, require expensive nitrogen fertilizer to flourish.

Why it matters

But what if bacteria could help those plants draw nitrogen from the atmosphere, as peas and beans do?

Common ground

New research from Washington State University takes an important step in that direction, identifying a key cluster of genes that can be moved from rhizobia bacteria that harvest nitrogen into bacteria that don't—raising the possibility that microbes that…
