Here we describe a novel way to improve the plant immune system by immune protease engineering. As proof of concept, we increased resistance against the late blight pathogen Phytopththora infestans by rendering the tomato secreted immune protease Pip1 insensitive to the P. infestans-secreted inhibitor Epic2B. This concept can be applied to secreted immune proteases in crops by precision breeding.Competing Interest StatementThe authors have declared no competing interest.
