BASAL AND INDUCED DISEASE RESISTANCE MECHANISMS IN ORNAMENTALS

M. Höfte
Ornamental plants are challenged by a wide range of biotrophic, hemibiotrophic and necrotrophic microbial pathogens. Here, an overview is given how plants defend themselves against these pathogens via a range of constitutive and inducible defense mechanisms. Inducible defense is triggered when pathogens break through the first line of pre-formed defense and is based on recognition of pathogen-or damage-associated molecular patterns and effectors by means of membrane or cytosolic receptors. Upon recognition a complex immune response is activated characterized by cell wall reinforcements, the induction of pathogenesis-related proteins, antimicrobial compounds and specific blends of plant hormones. Genomic strategies can help in identifying core effectors and corresponding receptors to obtain durable disease resistance. Induced resistance is a non-specific form of disease resistance in plants that can be triggered by a wide range of inducers of chemical or biological origin. We discuss how this knowledge can be applied to obtain disease resistance in ornamentals.
