A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. ... Rose yellow mosaic virus: Roymovirus:
Rose mosaic virus on R. "Queen Elizabeth" Rose mosaic – This mosaic virus disease is caused by a complex of viruses and is characterized by yellow patterns on the leaves. The patterns vary considerably, ranging between all-over fine blotches to patterns of lines in waves.
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.
rose yellow vein mosaic virus Prunus necrotic ringspot virus (PNRSV) is a plant pathogenic virus causing ring spot diseases affecting species of the genus Prunus , as well as other species such as rose ( Rosa spp.) and hops ( Humulus lupulus ).
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]
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).
Given the lack of knowledge of human infectious diseases at this time (and well into the 19th century) this was not an unusual conclusion, [15] but what is surprising is that while tulip mosaic disease has a far more impressive and documented history than any other plant virus, the realization that it was a communicable plant disease, let alone ...
