Outline of Final Research Achievements

We conducted virome analyses by the next-generation sequencer of cherry trees affected by a bud blight disease, apple trees by a russet ring disease, apple trees by a green crinkle disease, and apple trees by a mosaic-disease. The results indicated that two new viruses, Cherry virus B and Apple necrotic mosaic virus (ApMV) were detected from a cherry tree affected by a bud blight disease and mosaic-diseased apple trees, respectively. Furthermore, we found an Apple chlorotic leaf spot virus variant from a russet ring-diseased apple trees and this variant induced a russet-like symptom on fruits of inoculated apple seedlings.
