Sweet and sour cherry trees growing at new cultivar testing orchard and certified stock collection in Hungary are highly infected with CVA and PrVF

Original language description

Hungary has a long tradition of sour cherry breeding. Clone selection for new cultivars with desirable traits recently replaced by classical breeding, and new cultivar candidates waiting for evaluations of their phenotypes are maintained at a testing orchard. The viral status of these new sour cherry cultivar candidates was tested using small-RNA high-throughput sequencing (HTS) as an unbiased diagnostic method. Moreover, the viromes of certified stock collections of sour cherry and sweet cherry growing in the vicinity of the testing orchard were also determined. Bioinformatic analysis of the sRNA HTS was validated using unbiased methods, revealing that the trees had very high rates of cherry virus A (CVA) and Prunus virus F (PrVF) infections. The latter virus was described in Hungary for the first time. While the stock collection was free from Prunus necrotic ringspot virus (PNRSV), this regulated virus was present at the testing orchard. As a follow-up study, the survey of the testing orchard was repeated after two years using RT-PCR with a detailed survey of the stock collection. The infection pattern of the viruses suggests the spread of PNRSV via pollen at the testing orchard, where the trees can bloom. Notably, the strains of both CVA and PrVF varied to a large extent. A low concentration of virus-derived small RNAs suggests that they do not induce strong antiviral RNAi, which could explain why their infections can be latent, without visible symptoms. However, to determine the impacts of frequent coinfections on fruit yield and tree health, which could be further altered by the changing climate, further investigations will be needed in the future.
