Geminiviruses Versus Host’s Gene Silencing Mechanism

  • Omid EiniEmail author
Chapter

Abstract

RNA silencing is a well-known antiviral pathway that also controls geminiviruses at two levels: inhibition of viral transcription (TGS) and degradation of viral transcripts (PTGS). Plant viruses encode proteins to suppress this antiviral system. In this chapter, the gene silencing pathway and the steps in which the geminiviral suppressors act have been reviewed. More specifically, the type of viral small RNAs and their role in local and systemic silencing have been described. In addition, this chapter provides an overview of latest researches and findings in geminivirus–host interaction in gene silencing pathway.
