Potato virus M (PVM), pepino mosaic virus (PepMV), tomato mosaic virus (ToMV), and potato virus S (PVS) infect pepino and cause serious crop losses. In this study, a multiplex RT-PCR method was developed for simultaneous detection and differentiation of PVS, ToMV, PepMV and PVM. The method was highly reliable and sensitive; validation was accomplished by testing pepino samples collected from different regions of China. In this survey, PVM, ToMV and PVS were detected in 37.0 %, 31.0 % and 5.5 % of samples tested, respectively, confirming the widespread occurrence of these three viruses in China. PepMV was not detected in any of the samples, which indicated that this virus may not be prevalent in China. The results suggest that the new multiplex RT-PCR method has potential to be used routinely for surveys of pepino for virus infection.

UI MeSH Term Description Entries
D010935 Plant Diseases Diseases of plants. Disease, Plant,Diseases, Plant,Plant Disease
D002681 China A country spanning from central Asia to the Pacific Ocean. Inner Mongolia,Manchuria,People's Republic of China,Sinkiang,Mainland China
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed. ELISA,Assay, Enzyme-Linked Immunosorbent,Assays, Enzyme-Linked Immunosorbent,Enzyme Linked Immunosorbent Assay,Enzyme-Linked Immunosorbent Assays,Immunosorbent Assay, Enzyme-Linked,Immunosorbent Assays, Enzyme-Linked
D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives.
