What does potato virus X do?
Potato virus X has been used as model to study plant-virus interactions and to elucidate the plant-defense mechanisms and viral countermeasures such as suppression of silencing (Ruiz et al., 1998; Ratcliff et al., 1999).
What virus is a potato?
Disease Scenario
| S.No | Disease symptoms | Causal virus |
|---|---|---|
| 1. | Potato leaf roll | Potato leaf roll virus |
| 2. | Mild mosaic | Potato virus X |
| 3. | Yellow flecking | Potato acuba mosaic virus |
| 4. | Rugore mosaic | Potato virus Y |
Who discovered potato virus?
When Johnson (1925) found that the sap of potatoes which were apparently healthy, or which showed only a faint mottle on the leaves, was able to infect tobacco and other plants, he made the first contribution to the recorded history of potato virus X .
How do plant viruses spread?
Viruses can be spread by direct transfer of sap by contact of a wounded plant with a healthy one. Such contact may occur during agricultural practices, as by damage caused by tools or hands, or naturally, as by an animal feeding on the plant.
What causes potato mosaic?
Managing Potatoes with Mosaic Virus This virus is spread mechanically by machinery, irrigation equipment, root to root or sprout to sprout contact, and via other gardening tools. Both viruses A and Y are carried in tubers but are also transmitted by several species of aphids.
Which disease of potato is caused by Actinomyces?
Gussow renamed the species Actinomyces scabies, noting that Oospora was an incorrect classification since the disease was not caused by a fungus.
When was potato virus Discovered?
PVY, first isolated from potato in the 1930s as one of a complex of viruses associated with the century-old potato degeneration, is one of the most studied plant viruses and is the type member of the genus Potyvirus.
Can plants give humans viruses?
It is currently accepted that a strict separation exists between plant and vertebrate viruses regarding their host range and pathogenicity, and plant viruses are believed to infect only plants. Accordingly, plant viruses are not considered to present potential pathogenicity to humans and other vertebrates.
Do plant viruses exist?
Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses can be pathogenic to higher plants.
