| Cylindrocarpon destructans is the major pathogen inducing the root rot disease in ginseng. Up to now, there is no reliable and convenient method to analyze the spore density or population of this pathogen in ginseng-growing soil or any contaminated farmlands. Therefore, it will be very valuable to develop a new and reliable method in detecting the spore of this pathogen. In this study, a molecular biological technique using two step nested PCR method, was developed. Two universal ITS primers, ITS5F and ITS4R were used in the first round of PCR to amplify a fragment of ITS region from the genomic DNA of C. destructans. The specific prmers Nest 1 and Nest 2 were designed and used in the second round of PCR to amplify a inner fragment from the first round PCR product of C. destructans. C. destructans spore, only soil samples from the diseased ginseng farm produced the positive bands, suggesting its usefulness in detecting the C. destructans spores in soil samples. Thus it is recommended to first extract the whole genomic DNA from soil samples and use it for the PCR reaction, thereby eliminating the inhibitory activity of soil components. |
