Researchers from the Chinese Academy of Agriculture have used CRISPR-Cas9 gene-editing technology to remove two genes from the tomato genome, resulting in a 30% increase in glucose and fructose in the fruit. The study, published in Nature, aims to exploit the genetic diversity of wild species and enhance the taste of domesticated tomatoes, which are larger but less sweet than their wild ancestors. The new tomato variety could potentially reduce the energy and cost required for making tomato paste by cutting down on the need for sugar. The findings could also be applied to other plant species that contain these genes.
