Mechanism of Harpin Protein

As the diagram shows, Dora Immune works by stimulating the plant to grow under the general effects of stress and one of those stresses is fungal attack.

Harpin itself does not directly affect the pathogens, nor does it enter the plant, rather it binds to receptors on the plant leaf and thereby triggers physiological processes within the plant.
