Virus tolerance and recovery from viral induced-symptoms in plants are associated with transcriptome reprograming

Plant recovery from viral infection is characterized by initial severe systemic symptoms which progressively decrease, leading to reduced symptoms or symptomless leaves at the apices. A key feature to plant recovery from invading nucleic acids such as viruses is the degree of the host's initial basal immunity response. We review current links between RNA silencing, recovery and tolerance, and present a model in which, in addition to regulation...
