Abstract: The present invention pertains to the field of imparting or increasing resistance against fungal pathogens, in particular soy-beanrust, in plants, plant parts, and/or plant cells. This is achieved by increasing the content of scopoletin, scopolin and/or, most preferably, scoparone (6,7-di-methoxycoumarin) in a plant, plant part and/or plant cell. This can in particular be achieved by establishing and/or increasing the expression of an OMT3 enzyme and an F6H1 protein in the respective plant, plant part and/or plant cell; a further way would be to apply a formulation or solution containing scopoletin and/or, most preferably, scoparone to the plant, plant part and/or plant cell. The invention correspondingly also provides proteins, enzymes, expression constructs, plants, plant parts and/or plant cells. In this respect the invention also provides variants of the OMT3 enzyme.
