A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
More subtle patterning indicating rose mosaic virus. All cultivated species of the genus Prunus, which includes plums, cherries, apricots, almonds, and peaches, are susceptible to one or more strains of PNRSV. Hops and rose are also susceptible to infection by the virus.
This virus had been diagnosed in several ornamental plants since its discovery in 1999. These include moss rose (Portulaca grandiflora), phlox (Phlox stolonifera), skullcap (Scutellaria sp), firecracker plant (Crossandra infundibuliformis), angelonia (Angelonia angustifolia), Torenia sp, Helichrysum sp., and Salvia splendens.
Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (insects). Transmission routes are vector and mechanical. [2]
The genome of sobemoviruses exemplified by Sesbania mosaic virus. Solemoviruses have a positive-sense, single-strand RNA genome. The length of the genome is 4652 bp. The 3' terminus does not have a polyA-tail. The 5' terminus has a genome-linked viral protein (VPg).
Apple mosaic virus (ApMV) is a plant pathogenic virus of the family Bromoviridae. It is named after its symptoms that were first present on apples. [1] ApMV is a positive sense RNA based virus. [1] The disease itself has several synonyms including Mild Apple Mosaic Virus, Hop Virus, Rose Mosaic Virus, and European Plum Line Patten Virus. [2]
