ABSTRACT
In this study, a new SYBR Green qPCR (qRT-PCR) and a nested RT-PCR (nRT-PCR) were developed to detect Potato mop-top virus (PMTV) in potato tuber tissues. The SYBR Green qRT-PCR and nRT-PCR assays were approximately 104- and 103- fold more sensitive than the conventional RT-PCR assay. The progeny tubers derived from PMTV-infected potato tubers were tested by conventional RT-PCR, SYBR Green qRT-PCR and nRT-PCR assays. Of the 17 samples, 9 (52.9%) were positive for PMTV by conventional RT-PCR, 11 (64.7%) were positive by nRT-PCR, and 17 (100%) were positive by SYBR Green qRT-PCR. Compared to nRT-PCR, SYBR Green qRT-PCR was showed to be more sensitive. The progeny plants exhibited foliar symptoms including chlorosis and reduction in leaf size when the PMTV-positive tubers were planted in a growth chamber at 20-22⯰C. These findings suggest that PMTV has been passed on to the progeny plants and tubers.
