Resistance induced in Phaseolus vulgaris by a varietal nonpathogenic race of Colletotrichum lindemuthianum against a varietal pathogenic race is exhibited by cells distant from the inducing interaction. Induced resistance is expressed after the varietal pathogenic race has penetrated, and is microscopically indistinguishable from the resistant reaction to a varietal nonpathogenic race.
