Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed ‘BUZZ,’ causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.
