Description and significance

The apple mosaic virus is the agent for the apple mosaic disease. The apple mosaic virus is the most widespread apple virus. An apple tree infected with the ApMV will have pale to bright cream spots on the leaves. The distribution of the infected leaves may be depicted throughout the tree leaves or just a single tree limb. The ApMV infects U.S apple trees with the most infected being "Golden Delicious" and "Jonathan" apple trees. The virus is spread through through root grafting. Depending on how far the virus has spread, will determine the severity of apple loss. The apple mosaic virus is an important virus to study, since an infected apple tree results in decrease in crops.

Genome structure

The apple mosaic virus is a single molecule of linear, positive-sense, single stranded RNA. The complete sequence genome for apple mosaic virus RNA1 is about 1,046 nucleotides long, ApMV RNA 2 is about 875 nucleotides long, and apple mosaic virus RNA 3 complete sequence is about 265 nucleotides long. The viral genome encodes structural and non-structural proteins; the ApMV 1 and ApMV 2 encodes 1 structural protein, while ApMV RNA 3 encodes 2 structural proteins. The apple mosaic virus contains no lipids present.
