title: [Persistent Shallot virus X infection correlates with transcriptional repression of plant cell RNA-dependent RNA polymerase and DCL proteins in plant roots].
abstract: Shallot virus X is a typical representative of Allexiviruses. The transcription levels of principal genes involved in the RNA silencing in healthy and shallot virus X-infected plants have been quantified by real-time polymerase chain reaction. There is a negative correlation between the reproduction rates of RNA virus and the levels of RNA-dependent RNA polymerase and DCL proteins in roots and leaves of infected plants. These observations indicate that Shallot X virus employs noncanonical ways of overcoming the antiviral defense of the plant by systemic RNA silencing.
