摘要:

以松材线虫rDNA -ITS2为靶区,建立松材线虫的TaqMan探针实时荧光PCR检测方法。对松材线虫大量DNA和单条线虫的检测结果表明,探针检测松材线虫和拟松材线虫时,前者产生明显的荧光信号,后者无荧光信号,表明探针具有高度的特异性;探针检测到最低模板浓度为1pg·μL-1 ,DNA测序结果与实时荧光PCR结果一致。

Abstract:

A real time fluorescent PCR(ATF-PCR) method with TaqMan probe that was designed within rDNA-ITS2 was established to detect Pine Wood Nematode, Bursaphelenchus xylophilus. The results of detecting mass DNA and single nematode showed that fluorescent signal was detected for B. xylophilus and no signal for B. mucronatus. The BXP probe was high specific for Pine Wood Nematode. The lowest concentration detected by TaqMan probe was 1 pg·μL-1. The results of DNA sequence and ATF-PCR detection was coincidence. The research provided a new detection method for Pine Wood Nematode.
