1954Wheeler & Luke in Phytopathol. XLIV. 334/1 The toxic agent, tentatively designated ‘Victorin’, was partially purified by several methods. 1958Science 29 Aug. 477/2 Victorin affected only those varieties of oats that were susceptible to the fungus. 1972Ibid. 22 Sept. 1097/1 Results with victorin, the toxin involved in Victoria blight of oats, reawakened interest in the role of toxins in plant diseases. 1982J. B. Harborne Introd. Ecol. Biochem. (ed. 2) ix. 258 Victorin is a unique molecule in showing such a striking differential toxicity in cereal plants. |
