In the past decade, precise genome editing has transitioned from theory to practical application. Yet, plastid genomes have largely remained impervious to these advances. A recent breakthrough by Mok et al. (2024) demonstrated successful plastid genome editing by developing transgene-free atrazine-resistant arabidopsis (Arabidopsis thaliana) plants.
Keywords: chloroplast genome editing; high-precision; precise editing; transgene-free.
