Efficient A·T-to-C·G Base Editing via Adenine Transversion Editors.

Generating A-to-C transversions to correct defective alleles or introduce novel alleles has posed significant challenges. However, two recent studies focusing on adenine transversions have achieved successful A-to-C transversions in mouse embryos and plant cell. These remarkable accomplishments notably broaden the range of base editing and their applications both in fundamental research and in therapeutics.
