Scientists identify tomato genes to tweak for sweeter fruit

Chinese researchers identified two genes limiting sugar production in ripening tomatoes. Using gene-editing, they created larger, sweeter tomatoes without affecting yield. The modified tomatoes had up to 30% higher sugar content, with no significant difference in fruit weight or yield. These sweeter tomatoes could be available in supermarkets within three to five years. While gene-edited crops are supported by new laws in England and Wales, additional legislation is needed before they can be grown there.
