Gibberella fujikuroi strains isolated from rice in the United States, Asia, and other geographic areas were tested for sexual fertility with members of mating population D and for production of fumonisin B(inf1) and moniliformin in culture. Of the 59 field strains tested, 32 (54%) were able to cross with tester strains of mating population D, but only a few ascospores were produced in most of these crosses. Thirty-four strains produced more than 10 (mu)g of fumonisin B(inf1) per g, but only three strains produced more than 1000 (mu)g/g. Twenty-five strains produced more than 100 (mu)g of moniliformin per g, and 15 produced more than 1,000 (mu)g/g. Seven field strains produced both fumonisin B(inf1) and moniliformin, but none of these strains produced a high level of fumonisin B(inf1) (>1,000 (mu)g/g). However, a genetic cross between a strain that produced fumonisin B(inf1) but no moniliformin and a strain that produced moniliformin but no fumonisin B(inf1) yielded progeny that produced high levels of both toxins. Strains of G. fujikuroi isolated from rice infected with bakanae disease are similar to strains of mating population D isolated from maize in their ability to produce both fumonisins and moniliformin. This finding suggests a potential for contamination of rice with both fumonisins and moniliformin.
从美国、亚洲和其他地区的水稻中分离到的藤仓镰刀菌菌株与交配群体 D 的成员进行了有性生殖的测试，以检测其产生伏马菌素 B(inf1)和单端孢霉烯族毒素的能力。在测试的 59 个田间菌株中，有 32 个（54%）能够与交配群体 D 的测试菌株杂交，但在大多数这些杂交中只产生了少量的分生孢子。34 个菌株产生的伏马菌素 B(inf1)超过 10μg/g，但只有 3 个菌株产生的伏马菌素 B(inf1)超过 1000μg/g。25 个菌株产生的单端孢霉烯族毒素超过 100μg/g，15 个菌株产生的单端孢霉烯族毒素超过 1000μg/g。有 7 个田间菌株同时产生伏马菌素 B(inf1)和单端孢霉烯族毒素，但这些菌株均未产生高水平的伏马菌素 B(inf1)(>1000μg/g)。然而，一个产生伏马菌素 B(inf1)但不产生单端孢霉烯族毒素的菌株与一个产生单端孢霉烯族毒素但不产生伏马菌素 B(inf1)的菌株进行遗传杂交，产生的后代同时产生了高水平的两种毒素。从感染细菌性基腐病的水稻中分离到的藤仓镰刀菌菌株与从玉米中分离到的交配群体 D 菌株在产生伏马菌素和单端孢霉烯族毒素方面具有相似的能力。这一发现表明，水稻可能同时受到伏马菌素和单端孢霉烯族毒素的污染。
