Turnip Mosaic Virus Infection in a Perennial Arabidopsis Reduces Aphid Fecundity in the Natural Environment.

ABSTRACT: In plant-virus-vector tripartite relationships, it has been recognised that viral infections alter the physiological state of host plants, enhancing vector performance and facilitating virus transmission to other host individuals. Natural tripartite systems with perennial host plants are expected to persist for a long time through clonal propagation and the spread of virus-infected hosts. Under such circumstances, viral infection may negatively affect the vector, enhancing host vigour. We used the Arabidopsis halleri-turnip mosaic virus (TuMV)-aphid system to test this hypothesis. We compared aphid performance between TuMV-infected and uninfected plants, and host transcriptomes of intact, aphid-infested, TuMV-infected, and aphid-infested TuMV-infected plants. Fewer aphids were observed on
