Latest Cucumber mosaic virus Stories
University of Cambridge researchers have shown that viruses use aphids as pawns, discouraging the insects from permanently settling on already-infected crops and using this forced migration to spread infection to healthy vegetation.
Previous research has shown that plants and invertebrates use an immune response called the RNA interference (RNAi) pathway to build a weapon against a viral infection. New research has found a similar pathway in mammals.
CSIRO plant scientists have shed light on a problem that has puzzled researchers since the first virus was discovered in 1892 â€“ how exactly do they cause disease?
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.
Tobacco ringspot virus (TRSV) is a plant pathogenic virus in the plant virus family Comoviridae. It of the type species Comoviridae Genus Nepovirus. Nepoviruses are transmitted between plants by nematodes. It is easily transmitted by sap inoculation and transmission in seeds has been reported. IT was first observed in tobacco fields in Virginia in 1927. It is an isometric particle with a bipartite RNA genome. The virus can infect field grown crops, ornamentals, and weeds. The name comes...
