Apple Mosaic Virus (APMV) ApMV infects naturally apple, Prunus sp., roses, hazelnut and other species. Apple mosaic is identifiable in spring on foliage of particularly sensitive cultivars like Golden Delicious, Gala or Jonathan. ApMV used to be rare in European apple trees. It was disseminated by the widespread distribution of the first infected Granny Smith clones, where it is latent and produces no symptoms. Leaves develop pale yellow to bright cream-colored areas as they expand during early spring. Mosaic areas can be irregular or occur in bands along major veins. Growth may be retarded and yield reduced in sensitive cultivars. Nomenclature and Host Range (VIDE database) Sequence Info (NCBI database) Isolates in the Vienna Collection Detection methods
