Molecular genetic tools such as CRISPR-Cas gene editing systems are invaluable for understanding gene and protein function and revealing the details of a pathogen's life and disease cycles. Here we present protocols for genome editing in Phytophthora infestans, an oomycete with global importance as a pathogen of potato and tomato. Using a vector system that expresses variants of Cas12a from Lachnospiraceae bacterium and its guide RNA from a unified transcript, we first present a method for editing genes through the non-homologous end-joining (NHEJ) pathway.
