Unexpected antiviral defence in plant vascular tissue

Some viruses are restricted to the vascular system of plants and their interaction with their host is still poorly studied due to the difficulty of isolating these tissues. Scientists have studied the defence mechanism against the phloem-restricted turnip yellows virus (TuYV) in the model plant Arabidopsis thaliana. Genetic and high-throughput sequencing approaches combined with vascular tissue enrichment revealed a new complexity of the interplay between antiviral defence by RNAi and its suppression by the viral protein P0. This work is published in the journal Nucleic Acids Research.
