چکیده انگلیسی
Three degenerate primers, located at the NIb and CP gene regions, were designed for potyvirus detection. Using these primer pairs, 1.0-1.2Â kb cDNA fragments of the 3â²-terminal region of six potyviruses were successfully amplified from infected plant tissues. RT-PCR products were sequenced and found to be derived from the expected viruses. To identify further these potyviruses, sequences located between the 3â² end of the NIb gene and the 5â² end of the CP gene were chosen to design a series of species-specific probes. The probes were prepared by PCR with species-specific primers, immobilized onto nylon membrane, and then hybridized with DIG-labeled RT-PCR products amplified by potyvirus degenerate primers. The results suggested that species-specific cDNA probes plus reverse dot blot hybridization was able to identify correctly different species of potyviruses in single as well as mixed infections.
