Forty-three strains of Fusarium moniliforme isolated from infected maize and sorghum plants in Italy were assayed for their ability to produce fertile crosses with "A" and "F" mating population tester strains, in relation to their ability to produce fumonisins on maize substrate. Most of the strains isolated from maize (ear and stalk rot and maize-based feed), producing fumonisin B1 (FB1) and B2 (FB2) (up to 4,100 and 855 mg/kg, respectively), belonged to the "A" mating population. All of the strains isolated from sorghum belonged to the "F" mating population and produced little or no FB1 and FB2. This is the first report of the occurrence of mating population "F" in Europe. Our data on strains from Italy are consistent with previous studies from the United States that found significant differences in sexual fertility and fumonisin production between strains from maize and sorghum.
对从意大利受感染的玉米和高粱植株中分离出的43株串珠镰刀菌进行了检测，以评估它们与“A”和“F”交配型测试菌株产生可育杂交的能力，以及它们在玉米基质上产生伏马毒素的能力。从玉米（穗腐和茎腐以及以玉米为基础的饲料）中分离出的大多数菌株能产生伏马毒素B1（FB1）和B2（FB2）（分别高达4100毫克/千克和855毫克/千克），属于“A”交配型。从高粱中分离出的所有菌株都属于“F”交配型，产生的FB1和FB2很少或不产生。这是欧洲首次报道“F”交配型的出现。我们关于意大利菌株的数据与美国以前的研究一致，该研究发现玉米和高粱菌株在有性繁殖力和伏马毒素产生方面存在显著差异。
