| 摘 要： | 松干基褐腐病菌是我国重要的植物检疫性病原菌,为建立该病原菌准确、灵敏、快速的检测方法,根据该病菌与同属内形态与寄主上最接近的4个种的ITS差异区域,设计出一对特异性引物IW1、IW2,经PCR扩增,只有松干基褐腐病菌可得到约165 bp的产物,而其余作为对照的菌株均无此产物,其检测灵敏度为100 pg基因组DNA。此外,特异性引物IW1和IW2还适合于Real-timePCR,其检测灵敏度更低,为0.1 pg基因组DNA（20μL反应体系）。应用此2种方法均能成功的从人工污染了的松干基褐腐病菌的木块中检测出病原菌。

| Abstract: | Inonotus weirii is an important plant quarantine pathogen in China.In order to set up an accurate,sensitive and quick way to detect this pathogen,a pair of specific primers,i.e.,IW1,IW2 were designed on the basis of the differences in the internal transcribed spacer(ITS) sequences between I.weirii and four species in the genus Inonotus,which were mostly close to Inonotus weirii in terms of morphology.The results of PCR showed that a 165bp product was only obtained from the sample of I.weirii.The detection s... |
