摘要:
菜豆荚斑驳病毒(bean pod mottle virus,简称BPMV)是我国进境植物检疫性有害生物,建立快速灵敏的一步法逆转录重组酶聚合酶扩增(reverse transcription-recombinase polymerase amplification,简称RT-RPA)技术用于对BPMV的检测。根据BPMV基因组的保守序列,设计重组酶聚合酶扩增(recombinase polymerase amplification,简称RPA)技术特异性引物,对BPMV、南方菜豆花叶病毒(southern bean mosaic virus,简称SBMV)、大豆花叶病毒(soybean mosaic virus,简称SMV)、南芥菜花叶病毒(arabis mosaic virus,简称ArMV)及烟草环斑病毒(tobacco ringspot virus,简称TRSV)共5种病毒进行RT-RPA特异性验证;并设计5个模板浓度梯度,以验证RT-RPA方法的灵敏性。结果表明,建立的RT-RPA检测方法能够从BPMV样品中检测到198 bp的特异性条带,且仅需在40 ℃下恒温反应40 min,不需要特殊的仪器设备;特异性验证试验表明,除BPMV能检测到特异性条带外,其他4种病毒SBMV、SMV、ArMV、TRSV均未检测到特异性条带,证明该方法特异性好;RT-RPA检测BPMV的灵敏度达到10-4稀释度,说明所建立的RT-RPA方法灵敏性高。综上所述,建立的RT-RPA方法检测BPMV特异性强、灵敏度高,无需特殊的仪器设备,适合实验室或者现场快速检测。
