The high degree of structural complexity of plant cell wall polysaccharides has led to suggestions that some components might function as latent signal molecules that are released during pathogen infections and elicit defensive responses by the plant. However, there has been a paucity of genetic evidence supporting the idea that variation in cell wall composition plays a role in the outcome of host-pathogen interactions. Recently, several genetic studies have provided new lines of evidence implicating cell wall polysaccharides as factors in host-pathogen interactions.
