Carbohydrates in plant immunity and plant protection: roles and potential application as foliar sprays.
International audience; 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 manner similar to phytohormones. This review first describes the main classes of carbohydrates associated to plant immunity, their role and mode of action. More precisely, the state of the art about perception of "PAMP, MAMP, and DAMP (Pathogen-, Microbe-, Damage-Associated Molecular Patterns) type" oligosaccharides is presented and examples of induced defense events are provided. A particular attention is paid to the structure/activity relationships of these compounds. The role of sugars as…
POLYSACCHARIDE COMPOUNDS AND USE OF SAME FOR STIMULATING DEFENCE RESPONSES OF PLANTS AGAINST PATHOGENIC MICROORGANISMS
The present invention relates to novel oligogalacturonans having a degree of methylation of 0 and a degree of polymerisation of 1 to 10, and to use there of for stimulating defence responses of plants against pathogenic microorganisms.
