Abstract
Here we report a new host-specific toxin that is produced by Alternaria alternata and is the eight reported for the fungus. The causal pathogen of black spot of peach produced a toxin in culture filtrates and in spore germination fluids. Toxin productivity during spore germination was closely related to pathogenicity of the pathogen. The degree of sensitivity of host plants to the toxin was consistent with that of susceptibility to the pathogen. Further, the toxin enabled infection by conidia of saprophytic A. alternata in peach leaves. Several cultivars showed resistance to the toxin and the pathogen, although no cultivars had an immune response. The toxin fit the criteria of a host-specific toxin and was designated AP-toxin.
