CRISPR Gene Editing Boosts Tomato Sweetness by 30%, Reveals Genetic Key to Reducing Sugar Cravings

Nov 14, 2024, 11:07 AM

Recent studies reveal that genetics play a significant role in determining people's cravings for sugary foods. A gene called sucrase-isomaltase (SI) may influence individuals' preference for sugary foods, with potential applications for reducing sugar intake on a population level. Additionally, researchers have identified genetic regulators that can enhance the sweetness of tomatoes without compromising their size, weight, or yield. By using CRISPR gene editing, scientists have successfully increased the sweetness of tomatoes by 30%. The study, published in Nature, highlights that altering just two genes can significantly improve tomato sweetness. These findings could pave the way for genetically modifying other crops to improve their taste and nutritional value.
