Dynamics of signal perception, signaling and regulation of defenses in plant cell walls.

Abstract

The plant cell wall is well known to act as a physical barrier against invading pathogens. However, our recent studies have suggested that the plant cell wall can perceive pathogen signals and is involved in signaling and regulation of cell wall-based defenses. Here we will focus on a recently discovered role(s) of the plant cell wall in plant-pathogen interactions to unravel the complicated system underlying plant immunity.
