Intracellular sensing of viral RNA. Over the past few years, several cytoplasmic viral RNA sensors have been discovered (Box 1) that detect the genomic RNA of invading virions, RNA replication intermediates or transcription products, and subsequently induce type I IFN responses. Furthermore, some ...
RNA-directed DNA methylation (RdDM) is the major small RNA-mediated epigenetic pathway in plants. RdDM requires a specialized transcriptional machinery that comprises two plant-specific RNA polymerases — Pol IV and Pol V — and a growing number of accessory proteins, the functions of which in th...

DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic or

there are a number of viruses that utilize RNA as a template for transcription carried out by RNA-dependent RNApolymerases. There are many mechanistic similarities between the DNA- and RNA-templated reactions, but the RNA-dependent RNA polymerases often contain a subunit with sequences closely relat...
