Increasing interest is devoted to carbohydrates for their roles in plant immunity. Some of
them are elicitors of plant defenses whereas other ones act as signaling molecules in a …

Understanding the changes affecting the plant cell wall is a key element in addressing its
functional role in plant growth and in the response to stress. Pectins, which are the main …

We carried out transcriptional profiling analysis in 10-d-old Arabidopsis thaliana seedlings
treated with oligogalacturonides (OGs), oligosaccharides derived from the plant cell wall, or …

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 …

Abstract Wall-associated kinase 1 (WAK1) is a transmembrane protein containing a
cytoplasmic Ser/Thr kinase domain and an extracellular domain in contact with the pectin …

Plant responses to wounding and herbivore attack are orchestrated by complex signaling
pathways that link the production of chemical and physical signals at the wound site to …

Oligogalacturonides (OGs) are endogenous elicitors of defense responses released after
partial degradation of pectin in the plant cell wall. We have previously shown that, in …

Plants are continuously exposed to a myriad of abiotic and biotic stresses. However, the
molecular mechanisms by which these stress signals are perceived and transduced are …

Polygalacturonases (PGs) are produced by fungal pathogens during early plant infection
and are believed to be important pathogenicity factors. Polygalacturonase-inhibiting proteins …

Extracellular ATP is a known receptor agonist in animals and was previously shown to alter
plant growth, and so we investigated whether ATP derivatives could function outside plant …
