As simple organisms with a parasite nature,viruses have become masters in manipulating and subvertcellular components, including host proteins and organelles,to improve viral replication. Therefore, the understanding ofviral strategies to manipulate cell function disrupting plantdefenses and enhancing viral infection cycles is fundamentalto the production of virus-resistant plant lines. After invadingsusceptible plants, viruses create conditions that favor localand systemic infections by suppressing multiple layers ofinnate host defenses while use cellular machinery to ownbenefit. Viral interference in interlinked essential cellularfunctions results in phenotypic changes and disease symptoms,which debilitates plants favoring infection establishment. Herein in this review, the novelty it will be the discussionabout the strategies used by (+) single strand RNA viruses toaffect cellular processes and components to improve viralreplication, in parallel to overcome plant defenses, favoringdisease establishment by applying in one action using thesame viral protein to coordinate viral replication and breakingdown plant defense. This focus on plant-virus interactionwas never done before, and this knowledge has the potentialto help in the development of new strategies to produceresistant plants.
