Dynamic profiles of the rate of O_2 generation from press-injured and inoculated rice leaf slices, versus the time after inoculation, discriminated between the incompatible and compatible combination of blast fungus races with a cultivar. The application of sodium saccharin to rice seedlings via the root system for 6 days changed the compatible to incompatible profile. Even after press-injury and inoculation with the compatible conidia, the leaf application of sodium saccharin enhanced superoxide generation. The application of N-methylsaccharin in a similar manner, however, did not enhance the superoxide generation. Inoculation of press-injured leaves with incompatible conidia in the presence of an aqueous diffusate of the germinating compatible conidia changed the incompatible to compatible profile. The application to press-injured of concanavalin A or a lyophylized preparation from 5 M ammonia extracts of rice leaf homogenate prior to stimulating with a resistance-inducing factor (RIF) from the fungus also enhanced the superoxide generation. The RIF, either from the incompatible or compatible race, gave a quite similar profile of activation upon the generation of the superoxide anion.
