Corn that fertilises itself through aerial roots

A traditional variety of corn grown by people from Sierra Mixe in southern Mexico can thrive in poor soils without needing much extra fertiliser. A group of researchers have shown that the plant is able to draw nitrogen from the air through mucus-laden aerial roots on its stems. It’s hoped that the trait can eventually be bred into commercial corn strains.

The researchers have made a legal agreement with the Mexican government that any benefits from the research will be shared with the Sierra Mixe community.
