In a recent report in Genes & Development, El-Shami et al. (2007) show that in plants, Argonaute 4-which is involved in RNA-directed DNA methylation-directly associates with RNA polymerase IVb through a repeat motif, establishing an intimate molecular link between RNAi and transcription. | lld:pubmed |
