Since its discovery and first applications for genome editing in plants, the clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 technology has revolutionized plant research and precision crop breeding. Although the classical CRISPR-Cas9 system is a highly efficient tool for disruptive targeted mutagenesis, this system is mostly inefficient for the introduction of precise and predictable nucleotide substitutions. Recently, Prime Editing technology has been developed, allowing the simultaneous generation of nucleotide transitions and transversions but also short defined indels. In this study, we report on the successful use of Prime Editing in two plants of interest: the plant model Physcomitrium patens and the tetraploid and highly heterozygous potato (Solanum tuberosum). In both cases editing rates were lower than with other CRISPR-Cas9 based techniques, but we were able to successfully introduce nucleotide transversions into targeted genes, a unique feature of Prime Editing. Additionally, the analysis of potential off-target mutation sites in P. patens suggested very high targeting fidelity in this organism. The present work paves the way for the use Prime Editing in Physcomitrium patens and potato, however highlighting the limitations that need to be overcome for more efficient precision plant breeding.
