| 摘 要： | 菠萝凋萎相关病毒（Pineapple mealybug wilt associated virus-2，PMWaV-2）是引起的菠萝凋萎病（Mealybug wilt of pineapple，MWP）的重要病原。本研究中根据PMWaV-2外壳蛋白基因序列设计特异性引物和探针，建立基于TaqMan探针的实时荧光定量RT-PCR检测方法。该方法能高灵敏检测出阳性样品，对阴性样品及空白对照均无荧光反应；灵敏度比普通PCR高100倍；重复性试验表明批内和批间变异系数均在1.85%以内，表明本方法是一种操作简便、特异性强、灵敏度高、重复性较好的PMWaV-2定量检测方法。

| Abstract: | Pineapple mealybug wilt associated virus-2（PMWaV-2）is an important pathogen that causes Mealybug wilt of pineapple（MWP）. This study established a real-time quantitative RT-PCR method with TaqMan probe based on specific primers of conserved nucleotide sequence of PMWaV-2 coat protein gene. The results showed that the method is highly sensitive to positive sample，but has no fluorescence signal to health sample and water control. The sensitivity of real-time quantitative RT-PCR is about 100 times higher than regular PCR. Three-time repeats revealed that the coefficients of variation between the intra- and inter-assay were both within 1.85%，indicating a simple，specificity，high sensitivity，and reliable reproducibility detection method to PMWaV-2. |
