The Functions of RNA-Dependent RNA Polymerases in Arabidopsis [PDF]
One recently identified mechanism that regulates mRNA abundance is RNA silencing, and pioneering work in Arabidopsis thaliana and other genetic model organisms helped define this process. RNA silencing pathways are triggered by either self-complementary fold-back structures or the production of double-stranded RNA (dsRNA) that gives rise to small RNAs (

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]
tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a

RNA-dependent RNA polymerase of tobacco plants [PDF]
Several properties of RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6) active fractions obtained from tobacco plants, be they uninfected, infected with tobacco mosaic virus, or infected with tobacco necrosis virus, were compared.

RNA-dependent RNA polymerases of plants [PDF]
The existence of RNA-dependent RNA polymerases (EC 2.7.7.48) in plants has been definitely proven by their isolation in pure form from cucumber and tobacco in our laboratory and from cowpea at Wageningen. These enzymes are single-chain proteins of 100-130 kilodaltons. They show clear physical and biochemical differences characteristic for a given plant

RNA-specific ribonucleotidyl transferases [PDF]
RNA-specific nucleotidyl transferases (rNTrs) are a diverse family of template-independent polymerases that add ribonucleotides to the 3'-ends of RNA molecules.

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation [PDF]
There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.

Generation and characterization of a recombinant Rift Valley fever virus expressing a V5 epitope-tagged RNA-dependent RNA polymerase [PDF]
The viral RNA-dependent RNA polymerase (RdRp; L protein) of Rift Valley fever virus (RVFV; family Bunyaviridae) is a 238 kDa protein that is crucial for the life cycle of the virus, as it catalyses both transcription of viral mRNAs and replication of the

Functional characterization of Ysh1p, the yeast endonuclease involved in 3" end processing and in transcription termination of RNA polymerase II transcripts [PDF]
Eukaryotic RNA polymerase II (RNAP II) is involved in the synthesis of two major classes of transcripts: messenger RNAs (mRNAs) and small nuclear and small nucleolar RNAs.
