The World Under Our Feet is Filled With Smart Roots

A tiny tomato seed is planted just a quarter-inch below ground and watered. In about a week, the first stirrings of life become apparent–a tiny seedling punches up through the soil’s surface and unfurls baby cotyledon leaves. Over the ensuing weeks, the tiny plant grows to as much as eight feet high, with branches, dark green leaves and, later, bright yellow flower clusters and fruits cutting a robust silhouette. 

At the same time, that same expansion is happening just out of sight below ground. As the seedling emerges, the first white root starts plunging into the soil, providing support and searching for the water and nutrients the aboveground portion needs to fuel growth. Root growth is a critical aspect of plant health and agriculture, yet the process has remained obscured from view because it happens in the dirt. Careful inspection by scientists still generally requires they dig the plant up and remove the soil. 

Now researchers say they have a new way of watching the intricacies of root growth thanks to input from an unexpected source–fireflies. A science team has figured out how to get roots to glow by adding genes into them that produce the enzymes fireflies use to produce light.

It’s like a game. Repetitive. Even a little tedious after more than twenty years.

But there are much worse games to play…
