Prof. Sanwen Huang emphasized that balancing consumer demands for sweetness with farmers' needs for higher yields is vital. Their research introduces genes enabling sweeter yet sizable tomatoes.
The study identified two crucial genes that regulate sugar levels in tomatoes. Researchers used Crispr-Cas9 to edit these genes, leading to sweet tomatoes while maintaining desired size and yield.
Writing in Nature, the researchers explain that the genetic versions associated with high sweetness were lost in modern tomato varieties, a gap they aim to rectify.
