Description

Dibyendu Ghosh and three co-authors show how one plant virus helps another during mixed infection by muting the plant's antiviral defense. Mixed infections are common in fields and often worsen disease. The pair studied here joins a DNA virus of peppers with potato virus X, an RNA virus.

Plants carrying both viruses showed worse symptoms and higher levels of potato virus X than plants with that virus alone. Removing one viral protein, called V2, erased the boost. The protein blocks the plant's gene silencing defense by binding a host helper protein. A mutant unable to block silencing also failed to help. The same pattern held with a second virus pair in tomato.
