Sugarcane mosaic disease (SMD) caused by the Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV) and Sugarcane streak mosaic virus (SCSMV) and sugarcane yellow leaf disease (SYLD) caused by the Sugarcane yellow leaf virus (SCYLV) are the two most prevalent and economically important viral diseases of sugarcane. In this study, a one-step quadruplex reverse transcription (RT)-PCR method that employed virus-specific primers was developed for the simultaneous detection and differentiation of SCMV, SrMV, SCSMV and SCYLV. Several sets of primers for each target virus were evaluated for their sensitivity and specificity by simplex and quadruplex RT-PCR. The optimum primer combinations and concentrations, RT temperature and time, and PCR annealing temperature and extension time were determined for the quadruplex RT-PCR. The assay was then validated using sugarcane samples affected with SMD and/or SYLD collected from sugarcane breeding fields and farmers' fields in southern China.
