Latest Plant virus Stories
LMU researchers have identified the structural features that enable the innate immune system to discriminate between viral and endogenous RNAs in living cells.
A virus that typically infects plants has been found to infect honeybees and could be responsible for the widespread collapse of honeybee colonies.
On November 8th, JoVE, the Journal of Visualized Experiments, will introduce a new technique to aid in the development of defenses against diseases threatening food crops worldwide.
Using virus vector-mediated RNAi enables scientists to rapidly study the function of insect genes.
Biologists have described only a few thousand different viruses so far, but a new study reveals a vast world of unseen viral diversity that exists right under our noses.
Virally structured nano-electrodes boost energy capacity ten-fold COLLEGE PARK, Md., Dec. 6, 2010 /PRNewswire-USNewswire/ -- Viruses have a bad rep--and rightly so. The ability of a virus to quickly and precisely replicate itself makes it a destructive scourge to animals and plants alike.
University of Illinois researchers have confirmed the first report of a potential new virus belonging to the genus Marafivirus in switchgrass, a biomass crop being evaluated for commercial cellulosic ethanol production.
Scientists have pinpointed specific mutations that allow a common plant virus to infect new species, according to research published in the March issue of the Journal of General Virology.
A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones.
Findings may lead to new ways to protect crops and make other useful products.
A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses have been described in detail although there are millions of different types. They are found in...
Potato virus Y (PVY) is a plant pathogenic virus of the family Potyviridae. It is one of the most important plant viruses affecting potatoes. Infection results in various symptoms depending on the strain. Production loss is the most mild of the symptoms and "˜potato tuber necrotic ringspot disease' is the worst. Ringspot renders potatoes unmarketable and can therefore result in a major loss of income. Aphid vectors transmit PVY but it can also remain dormant in seed potatoes. The South...
