Study finds what gets plant roots to grow strong

1 Min Read

A biological mechanism familiar to people who fast helps plant roots grow strong. The discovery by University of Copenhagen scientists provides an answer to a long-unanswered question and a deeper understanding of the “mouths” of plants that can help to develop climate-resilient crops.

Imagine eating with your feet and having half your body underground. Such is the life of most plants, with roots as the mouths through which they eat and drink. Roots also serve to anchor plants and keep them safe in wind and rain. Indeed, roots are critical for a plant’s life.

But many things remain unknown about the life of plants. How they grow their roots big and strong has long been a question and there are key pieces missing to the puzzle.

In a new study published recently, researchers from the University of Copenhagen’s Department of Biology share their discovery of how plants control root growth.
