Development of Quantitative Real-Time PCR Assays for Rapid and Sensitive Detection of Two Badnavirus Species in Sugarcane.

ABSTRACT: Sugarcane-infecting badnaviruses (sugarcane bacilliform viruses, SCBVs) represent a genetically heterogeneous species complex, posing a serious threat to the yield and quality of sugarcane in all major producing regions. SCBVs are commonly transmitted across regions by the exchange of sugarcane germplasm. In this study, we develop two quick, sensitive, and reliable protocols for real-time quantitative PCR (qPCR) of Sugarcane bacilliform MO virus (SCBMOV) and Sugarcane bacilliform IM virus (SCBIMV) using two sets of TaqMan probes and primers targeting the reverse transcriptase/ribonuclease H (RT/RNase H) region. The two assays had a detection limit of 100 copies of plasmid DNA and were 100 times more sensitive than conventional PCR. High specificity of the two assays was obser
