Cucurbit yellow stunting disorder virus (CYSDV) is a single-stranded positive-sense RNA virus that produces devastating disease in watermelon and squash. Foliar symptoms of CYSDV consist of interveinal yellowing, brittleness, and thickening of older leaves leading to reduced plant vigor. A rapid diagnostic method for CYSDV would facilitate early detection and implementation of best viral-based management practices. We developed a rapid isothermal reverse transcription-recombination polymerase amplification (exo RT-RPA) assay for the detection of CYSDV. The primers and a 6-fluorescein amidite (6-FAM) probe were developed to target the nucleocapsid gene. The real-time assay detected CYSDV at 2.5 pg purified total RNA extracted from CYSDV-infected leaf tissue and corresponded to 10 copies of the target molecule. The assay was specific and did not cross-react with other common cucurbit viruses found in Florida and Georgia. The performance of the exo RT-RPA was evaluated using crude extract from 21 cucurbit field samples and demonstrated that the exo RT-RPA is a rapid procedure, thus providing a promising novel alternative approach for the detection of CYSDV.
