(Newser) - Tomatoes would be about the size of blueberries if it weren't for two key genetic mutations, Reuters reports. Scientists mapping the plant's DNA discovered one gene that encourages additional cell division, and another that allows the fruit to grow many more internal compartments. Together the changes have created tomatoes up... More »
