Editing a Genome to Make Plants Yield More

Caption

Using CRISPR to create different sets of mutations in a gene promoter called SICLV3 (and in several other promoters) enabled researchers to vary the number of floral organs and locules (gelatinous seed compartments) in tomato, over a wide range. The effect is analogous to turning a dimmer switch to vary light levels over a continuous range. The result is the ability to adjust key traits to affect yield.
