Increasing flavonoid contents of tomato fruits through disruption of the SlSPL‐CNR, a suppressor of SlMYB12 transcription activity.

This article discusses the potential for increasing the flavonoid content in tomato fruits through the disruption of a gene called SlSPL-CNR. Flavonoids are important compounds that contribute to the color and health benefits of fruits. The researchers found that the SlSPL-CNR gene negatively regulates flavonoid biosynthesis by repressing the transcriptional activity of another gene called SlMYB12. By using the CRISPR/Cas9 gene editing system to disrupt the SlSPL-CNR gene, the researchers were able to increase the flavonoid content in tomato fruits. This study provides valuable information for improving the quality of tomatoes through breeding. [Extracted from the article]
