在山东省莱阳的温室大棚中发现,番茄叶霉病病菌Passalora fulva的霉层上发生一种重寄生真菌,导致番茄叶霉病菌的橄榄绿色霉层被一种白色真菌菌丝体覆盖最终导致番茄叶霉的完全崩溃。通过分离培养获得了该重寄生菌的单孢菌株HMQAU130012,经形态学观察和rD NA-ITS基因序列分析确定该重寄生真菌为垫形汉斯霉Hansfordia pulvinata,这是番茄叶霉重寄生真菌在我国的首次报道。 In a greenhouse in Laiyang, Shandong Province, it was found that a parasitic fungus occurred on the mold layer of the tomato leaf mold Passalora fulva causing the olive green mold coat of the tomato leaf mold to be covered with a white fungal mycelium that eventually led to the tomato Leaf mold completely collapsed. The isolated strain was used to obtain the monoclonal strain HMQAU130012, which was confirmed by morphological observation and rD NA-ITS gene sequence analysis. The heavy parasitic fungus was identified as Hansfordia pulvinata, My first report.
