Secret new weapon of insect-transmitted viruses exposed

Findings by a team of scientists, including two from the University of California, Riverside, could provide critical knowledge to attack deadly viruses transmitted by arthropods such as mosquitoes and aphids.

Virus attracts bumblebees to infected plants by changing scent

Plant scientists at the University of Cambridge have found that the cucumber mosaic virus (CMV) alters gene expression in the tomato plants it infects, causing changes to air-borne chemicals - the scent - emitted by the plants. ...

Plants can 'switch off' virus DNA

A team of virologists and plant geneticists at Wageningen UR has demonstrated that when tomato plants contain Ty-1 resistance to the important Tomato yellow leaf curl virus (TYLCV), parts of the virus DNA (the genome) become ...

Crop-infecting virus uses aphids as carrier

(Phys.org) —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 ...

Virus pulls bait and switch on insect vectors

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. In the process, the insects rapidly transmit ...
