Triple Determinate Mutations in Tomatoes (IMAGE) Cold Spring Harbor Laboratory Caption When three specific genetic mutations are combined and tuned just right, scientists can turn tomato plants into extremely compact bushes ideal for urban agriculture. Just two of these mutations (insert, left) shortens the normally vine-like plants to grow in a field, but all three (insert, right) causes their fruits to bunch like grapes. Researchers cut away the plant's leaves for a clearer view of the new tomatoes.
