摘　　要：对尖孢镰刀菌10个专化型18个菌株进行分析发现,在尖孢镰刀菌大豆专化型(Fusarium oxysporum f.sp.glycines 1193-3)中存在双链RNA,由6种成分组成,其大小分别为3.8kb、3.0kb、2.4kb、0.48kb、0.43kb和0.21kb,该菌株气生菌丝少,形成大量的粉红色分生孢子堆,并发生角变。The presence of double-stranded RNAs were demonstrated in Fusarium oxysporum f. sp. glycines 1193 - 3 after screening 18 strains (10 formae speciales) of Fusarium oxysporum. The dsRNA genome contains six components with sizes of 3. 8kb,3. Okb , 2. 4kb, 0. 48kb and 0. 21kb. This strain has two morphological variations-sectoring and large production of pink conidia.
