TUTase mediated uridylation of mRNA promotes degradation. Here, Scheer, de Almeida et al. show that Arabidopsis TUTase URT1 interacts directly with the translation inhibitor and decay factor DECAPPING5 and suppresses siRNA biogenesis by preventing ac

Uridylation emerges as a key modification promoting mRNA degradation in eukaryotes. In addition, uridylation by URT1 prevents the accumulation of excessively deadenylated mRNAs in Arabidopsis. Here, we show that the extent of mRNA deadenylation is co

In plants, post-transcriptional gene silencing (PTGS) represses gene expression by translation inhibition and cleavage of target mRNAs. The slicing activity is provided by argonaute 1 (AGO1), and the cleavage site is determined by sequence complement

Plant RNA viruses form organized membrane-bound replication complexes to replicate their genomes. This process requires virus- and host-encoded proteins and leads to the production of double-stranded RNA (dsRNA) replication intermediates. Here, we de

Uridylation is a widespread modification destabilizing eukaryotic mRNAs. Yet, molecular mechanisms underlying TUTase-mediated mRNA degradation remain mostly unresolved. Here, we report that the Arabidopsis TUTase URT1 participates in a molecular netw

Groundbreaking discoveries have uncovered the widespread post-transcriptional modifications of all classes of RNA. These studies have led to the emerging notion of an 'epitranscriptome' as a new layer of gene regulation. Diverse modifications control

RNA uridylation consists of the untemplated addition of uridines at the 3′ extremity of an RNA molecule. RNA uridylation is catalysed by terminal uridylyltransferases (TUTases), which form a subgroup of the terminal nucleotidyltransferase family, t
