| Agrobiological products have a clear potential to reduce the use of chemical pesticides and fertilizers in agriculture. Some plant cell wall-derived carbohydrates act as danger signalling molecules, so-called Damage-Associated Molecular Patterns (DAMPs), triggering receptor-mediated innate immune responses across different plant species. For example, oligogalacturonides, originated from pectin, are well-known DAMPs that increase crop tolerance to microbial disease. Plant lignocellulose is mostly made up of secondary cell wall, which is a complex structure, mainly consisting of carbohydrate polymers (cellulose and hemicelluloses) and lignin. In a project aiming to obtain new carbohydrate-based biostimulating or crop protecting products, different sources of lignocellulosic biomass were processed by a combination of physicochemical and enzymatic extraction methods. One fraction, PRB11, has been further tested by a set of assays to study hallmarks of immune response in plants (Calcium influx, Reactive Oxygen Species production, Mitogen-Activated Protein Kinase phosphorylation and expression of immunity-related genes). PRB11 has also been tested for its potential to increase plant resistance to pathogens. The results obtained in experimental greenhouse, using different plant-pathogen interaction systems, indicate that PRB11 is a good candidate for future agricultural application. | |
