Targeted mutagenesis in Arabidopsis and medicinal plants using transposon‐associated TnpB

The programmable nuclease TnpB is significantly smaller than Cas9, can edit genes in medicinal plants, including Artemisia annua, Salvia miltiorrhiza, Scutellaria baicalensis, Isatis indigotica, and Codonopsis pilosula, and has potential uses in molecular breeding to enhance crop yield and quality.
