title: Production of DON-related trichothecenes byFusarium graminearum Schw from Krasnodarski krai of the USSR.
abstract: 34Fusarium graminearum Schw isolates produced 4-deoxynivalenol to form significant amounts of 4, 7 - dideoxynivalenol and lesser amounts of 4 - deoxynivalenol monoacetates on grain substratesin vitro. This is the first report on the capability a large group of naturally occurring isolates to produce 4,7-dideoxynivalenol. The average levels of 4,7-dideoxynivalenol on rice, corn, barley, and wheat as a substrate were respectively 26.8, 14.0, 12.8, and 10.5% of the level of 4-deoxynivalenol. 4, 7 - dideoxynivalenol was present in all examined naturally contaminated wheat kernel samples at levels of 1.7 to 7.9% of the level of 4-deoxynivalenol. These findings suggest that more attention should be given to the occurrence of 4,7-dideoxynivalenol in cereals.
