Introduction.Pseudomonas syringae pv. actinidiae (Psa) has emerged as a major bacterial pathogen of kiwifruit cultivation throughout the world.Aim. We aim to introduce a CRISPR-Cas9 system, a commonly used genome editing tool, into Psa. The protocols may also be useful in other Pseudomonas species.Methodology. Using standard molecular biology techniques, we modified plasmid pCas9, which carries the CRISPR-Cas9 sequences from Streptococcus pyogenes, for use in Psa. The final plasmid, pJH1, was produced in a series of steps and is maintained with selection in both Escherichia coli and Psa.Results. We have constructed plasmids carrying a CRISPR-Cas9 system based on that of S. pyogenes, which ca..
