Potato leafroll virus (PLRV), genus Polerovirus, family Luteoviridae, is a major pathogen of potato worldwide. PLRV is transmitted among host plants by aphids in a circulative non‐propagative manner.

Previous studies have demonstrated that PLRV infection increases aphid fecundity on, and attraction to, infected plants as compared to controls. However, the molecular mechanisms mediating this relationship are still poorly understood.

In this study, we measured the impact of PLRV infection on plant‐aphid interactions and plant chemistry in two hosts: Solanum tuberosum and Nicotiana benthamiana.

Our study demonstrates that PLRV infection attenuates the induction of aphid‐induced jasmonic acid and ethylene in S. tuberosum and N. benthamiana.
