    Apple stem pitting virus - CAB Direct

    Apple stem pitting virus (ASPV) is a widespread pathogen of pome fruit trees, and was first reported in Malus sylvestris from Midwest of USA. ASPV causes xylem pits in the stem of Malus pumila Virginia Crab and epinasty and decline of Spy 227 (ornamental Malus sp.). The virus is also the causal agent of necrotic spot and vein yellows diseases of pear (Pear vein yellows virus-PVYV). Apple Green Crinkle Disease. Causative agent: Trees with green crinkle disease are infected with Apple Stem Pitting Virus (ASPV), Apple Stem Grooving Virus (ASGV), and Apple Chlorotic Leaf Spot Virus (ACLSV), but it is not known which are responsible for the disease.

    Among the most commonly reported viruses are apple stem pitting virus (ASPV), apple stem grooving virus (ASGV) and apple chlorotic leaf spot virus (ACLSV), all species of the family Betaflexiviridae. These viruses are ubiquitous and frequently occur as mixed infections. They are commonly called latent viruses because they usually do not induce obvious symptoms in most cultivars used in ... In this study, 267 coat protein gene (CP) sequences from 48 Polish isolates of Apple stem pitting virus (ASPV) were determined. The genetic structure of the virus population was analysed and possible mechanisms of molecular evolution explored. We found evidence of recombination within the ASPV population and the presence of 17 ASPV molecular variants that differ in the length, number and ... However, the species also develops severe symptoms after infection with other apple viruses, e.g., Apple stem pitting virus (ASPV). Therefore, it is difficult to distinguish ACLSV infection from ASPV infection when the plant is doubly infected with both viruses.
