Plant responses against invasive nucleic acids: RNA silencing and its suppression by plant viral pathogens.

Abstract excerpt

RNA silencing is a common strategy shared by eukaryotic organisms to regulate gene expression, and also operates as a defense mechanism against invasive nucleic acids such as viral transcripts. The silencing pathway is quite sophisticated in higher eukaryotes but the distinct steps and nature of effector complexes vary between and even within species. To counteract this defense mechanism viruses have evolved the...
