Transgene‐free CRISPR/Cas9‐mediated gene editing through protoplast‐to‐plant regeneration enhances active compounds in Salvia miltiorrhiza.

This article discusses a study on gene editing in Salvia miltiorrhiza, a plant used in Eastern medicine to treat cardiovascular diseases. The researchers developed a protoplast regeneration system for S. miltiorrhiza using CRISPR/Cas9 gene editing technology. They targeted seven transcription factor genes involved in the production of bioactive compounds in the plant. The study demonstrated high-efficiency gene editing and the regeneration of knockout plants, which could potentially enhance the contents of active compounds in medicinal plants.
