Zachary Lippman, José Jiménez-Gómez and colleagues show that cultivated tomatoes have lost day-length-sensitive flowering, compared to their wild relatives, as a result of cis-regulatory variation affecting expression of SP5G, a paralog of the florigen gene SFT. They engineered SP5G loss-of-function mutant plants, resulting in rapid flowering and early yield.
