Cross protection in plants
WebPlants pre-infected with a mild variant of a virus frequently become protected against more severe variants of the same virus through the cross protection phenomenon first discovered in 1929. Despite its widespread use in managing important plant virus diseases, the mechanism of cross protection remains poorly understood. WebCross-protection is a phenomenon in which plants are inoculated with mild strains of viruses or viroids to prevent more virulent strain viruses from infecting the plant. …
