Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces SN/T 2055-2008 “Quarantine Heavy Mosaic Virus Quarantine and Identification Methods”, compared with SN/T 2055-2008, mainly The changes are as follows. --- Increased routine RT-PCR detection methods; --- Added real-time fluorescence RT-PCR detection method. This standard is proposed and managed by the National Certification and Accreditation Regulatory Commission. This standard is drafted by. China Academy of Inspection and Quarantine, People's Republic of China, Jiangsu Entry-Exit Inspection and Quarantine Bureau, Chinese Republic of China Xiamen Entry-Exit Inspection and Quarantine Bureau.

3 Basic information

Scientific name. Cowpeaseveremosaicvirus Abbreviation. CPSMV Taxonomic status. Associated Secoviridae, Comovirinae, Cowpea Mosaic Virus (Comovirus). See Appendix A for additional information on this virus.

4 Methodology

According to the specific reaction between cow bean heavy mosaic virus and antibody, ELISA test of plant samples. According to the nucleic acid of the virus PCR-specific detection of the sequence, determination of the result by electrophoretic band size, design of specific primers based on the nucleic acid sequence of the virus, and Fluorescent probes are used to determine the result of the detected fluorescence signal.
