Popis:	Conidia of Cochliobolus carbonum secrete a toxin (HC-toxin) during appressorium formation on maize leaves. Plasma desorption mass spectrometry revealed that approximately 70 ng of toxin per 106 conidia were secreted during the first 16 h of morphogenesis. Growth of the fungus was monitored microscopically. Extensive fungal growth occurred in the susceptible interaction by 24 h. In spite of a substantial amount of HC-toxin, the fungus failed to become established in the resistant host even after 36 h. Results suggest that the resistance conditioned by Hm1, which encodes a toxin reductase, causes inactivation of the toxin early in the interaction.
