Investigating the Occurrence of Viruses in Sweet Cherry in China and Developing Multiplex RT-PCR Assays for Their Detection.

ABSTRACT: Sweet cherry (Prunus avium L.) cultivation in China covers an estimated area of 25,600 hectares, representing more than one-third of the global total. Viral diseases present a serious challenge to cherry production worldwide; however, the phytosanitary status of sweet cherry in China has remained poorly understood. In this study, 191 sweet cherry samples were collected from major growing regions and screened using RT-PCR combined with DNA sequencing for the presence of 14 viruses previously reported in China. Results revealed that 80.1% of the tested samples were infected with at least one virus, with mixed infections detected in 51.3% of the samples. Prevalent viruses included cherry virus A (CVA, 53.4%), prunus necrotic ringspot virus (PNRSV, 35.1%), cherry green ring mottle virus
