The host-specific toxin produced by the plant pathogen, Helminthosporium carbonum Ullstrup is normally about 300 times as toxic for corn plants susceptible to the disease as it is for disease-resistant plants. Electrolytic reduction of the toxin destroys this specificity, rendering the material no more toxic for disease susceptible plants than for disease resistant ones.
植物病原体旋孢腔菌产生的种属特异性毒素通常对易患该疾病的玉米植株的毒性是对抗病植株的毒性的约 300 倍。该毒素的电解还原破坏了这种特异性,使该物质对易感病植物的毒性与对抗病植物的毒性相同。
