Selection for bigger tomatoes has made the fruits less sweet, but now it has been shown that gene editing can make them sweeter without decreasing yields

Rotten tomatoes no more: growing sweeter tomatoes is possible by editing just two of the fruit’s genes. Deleting the genes increased the engineered fruits’ glucose and fructose levels by up to 30% over mass-produced tomatoes, according to a study 1 published today in Nature.

I n a groundbreaking study published in the journal Nature, researchers have successfully used gene editing to create sweeter tomatoes without compromising their size or yield. By
