Crown Roots (IMAGE) Carnegie Institution for Science Caption Roots systems of plants were revealed using the GLO-Roots luminescence imaging system, which uses a firefly protein to visualize roots in soil. The root system on the left is from an early stage plant that is just beginning to initiate crown roots, whereas the plant on the right has a crown root system that is fully established. Crown roots are false colored in red. Image is courtesy of Jose Sebastian.
