摘要
A real time reverse-transcription polymerase chain reaction (RT-PCR) was developed for efficient detection of Cucumber green mottle mosaic virus (CGMMV). The method was designed to use a duo-primer system with a TaqMan probe targeting the conserved sequence in 3' noncoding region (NCR) of CGMMV to detect isolates of this virus collected in China. The sensitivity of the real time RT-PCR assay was 0.13 pg of total RNA or 50 molecules of RNA transcripts. This level of sensitivity indicated that the one step real time RT-PCR developed in the present study could be used for routine testing assays. The real time RT-PCR method could assist in the implementation of quarantine measures for prevention and control of the disease caused by CGMMV. (c) 2008 Elsevier B.V. All rights reserved.
