- 摘要:
- 菜豆荚斑驳病毒(Bean pod mottle virus,BPMV)是我国进境植物检疫性有害生物。为解决普通RT-PCR不能直接检测大豆病种子中该病毒的问题,将简便快速的胶体金免疫层析技术(GICA)和高灵敏度的普通RT-PCR检测技术有机地结合起来,建立了GICA-RT-PCR检测新方法。即先用GICA捕获病毒,将捕获的病毒直接进行RT-PCR扩增,简化了检测的步骤,提高了检测的灵敏度。结果表明:用该方法检测提纯病毒灵敏度达到0.01μg.mL-1、检测大豆病叶和病大豆种皮,灵敏度达到 10-4,分别比GICA检测提高了20倍、10倍和100倍。GICA-RT-PCR可进一步确认GICA的结果。
- Abstract:
- 1Plant Protection School,Anhui Agricultural University,Hefei 230036,Anhui;2Institute of Animal and Plant Quarantine,Chinese Academy of Inspection and Quarantine,Beijing 100029,ChinaAbstract: Bean pod mottle virus(BPMV)is a quarantine pest for China.A high sensitive and rapid gold immunochromatography assay-RT-PCR(GICA-RT-PCR )method has been developed for the detection of BPMV- infected soybean seed.This method takes the advantage of gold immunochromatography assay(GICA)which captures the virus first on test line,then the immunocaptured virus will be used for direct RT-PCR to amplify the target nucleic acid,eliminating the need for traditional total RNA extraction methods and reducing the number of steps involved.The sensitivity of the GICA-RT-PCR for purified virus is 0.01 μg.mL-1.BPMV-infected soybean leaves and soybean seed coat diluted to 10-4can be detected by GICA-RT-PCR.GICA-RT-PCR is 20 times,10 times and 100 times more sensitive than GICA for detecting purified BPMV,BPMV-infected soybean leaves and soybean seed coat,respectively.GICA-RT-PCR is a simple and sensitive tool for confirmation of GICA results.
