Chloroplast alchemy: rewriting the chloroplast genome with high precision.

Abstract

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.
