摘要: 通过西瓜枯萎病菌与其他专化型枯萎病菌及瓜类几种重要病原菌的比较基因组分析,获得了西瓜枯萎病菌的基因组特异序列。在此基础上,设计出特异引物,筛选可扩增出西瓜枯萎病菌特异性DNA条带的引物。将特异性引物和尖孢镰刀菌专化型的通用引物W106R/W106S结合,建立双重PCR检测体系。该双重PCR检测体系可以在一次PCR反应中快速、准确的检测出西瓜枯萎病菌,为通过分子方法快速鉴定西瓜枯萎病菌提供技术支持。

Abstract: Based on the genome comparison analysis between Fusarium oxysporum f. sp. niveum(Fon)and other closely-related pathogens, the specific sequences of Fon were obtained. Then we developed specific primers that could amplify Fon-specific DNA bands. Combined the Fon-specific primers with the universal primer of Fusarium oxysporum (W106R/W106S), we established a duplex PCR method that might rapidly and accurately detect Fon by 1 PCR reaction, which is beneficial to technically support the rapid identification of Fon by method of molecular detection..

Key words: Fusarium oxysporum f. sp. niveum, duplex PCR, Fusarium oxysporum
