| The cell wall provides a passive barrier against pathogens and pests, is a reservoir of antimicrobial compounds and a source of signalling molecules. During microbial infection cell wall perturbations occur that lead to changes in gene expression. The characterization of plant resistance to necrotrophic pathogens has revealed the regulatory function of cell wall in the control of Arabidopsis thaliana immune responses. Thus, mutants impaired in Cellulose synthases (CESAs) required for the synthesis of cellulose from secondary cell wall show a constitutive accumulation of a diverse set of antimicrobial compounds, which lead to a broad-spectrum resistance to pathogens. Biased resistance screenings of Arabidopsis cell wall mutants have been performed, and novel signal transduction pathways and regulatory proteins controlling plant innate immunity have been identified, further corroborating the relevance of cell wall in the regulation of plant resistance to pathogens. In line with these results, the Receptor-Like-Kinases (RLKs) ERECTA, which is required for Arabidopsis resistance to different type of pathogens, was proposed to regulate cell-wall-mediated defense responses. Plant RLKs have been suggested to be important components of the cell-wall monitoring integrity pathway, and also to regulate basal resistance to pathogens through the recognition of molecular-associated microbial patterns. The characterization of the genetic interaction among these novel components of innate immunity will contribute to develop new crop protection strategies. | |
