The interaction between Cucumber mosaic virus (CMV) and Turnip crinkle virus (TCV) in Arabidopsis thaliana is reported. Although TCV coat protein accumulates to a similar level in singly or doubly infected plants, CMV coat protein is significantly decreased in doubly infected plants, which develop symptoms similar to those of TCV infection alone. TCV thus strongly interfers with infection by CMV. A significant reduction in CMV 2b gene expression also occurs in co‐infected plants. A defence signalling initiator, salicylic acid (SA), further inhibits CMV accumulation during CMV–TCV co‐infection. This interference is correlated with both enhanced virus gene silencing and defence signalling.
