Natural elicitors, effectors and modulators of plant responses

Abstract

Covering: up to April 2012

In plants, successful defense relies on fast and specific response to biotic attack. In plant–microbial and plant–plant interactions several elicitors, effectors and modulators are recognized by specific and unspecific receptors that trigger signal cascades eventually leading to gene expression and plant responses. Here we review the chemical nature and signaling pathways of natural products released by microorganisms, herbivores, and plants during pathogenic infections, herbivory, symbioses and allelopathic interactions.
