Finding the right template: RNA Pol IV, a plant-specific RNA polymerase

Mol Cell. 2005 Mar 18;17(6):754-6. doi: 10.1016/j.molcel.2005.03.003.

Abstract

A paradox of RNA-directed transcriptional silencing is that low-level transcription through the silenced locus is observed and may help maintain the silenced state. Discovery of a plant-specific RNA polymerase that directs heterochromatic silencing helps to resolve this issue.
