Summary
Defense mechanisms of plants against pathogens often entail cell wall strengthening, ethylene biosynth-
esis, expression of pathogen-related proteins and hypersensitive responses (HR). Pathogen-derived elicitors
trigger these defense responses. The Elicitor Ethylene-inducing Xylanase (EIX) elicits HR and other plant
defense responses in some tobacco and tomato cultivars independently of its xylan degradation activity.
