A novel fry1 allele reveals the existence of a mutant phenotype unrelated to 5'->3' exoribonuclease (XRN) activities in Arabidopsis thaliana roots. [PDF]
PLoS ONE, 2011 Mutations in the FRY1/SAL1 Arabidopsis locus are highly pleiotropic, affecting drought tolerance, leaf shape and root growth. FRY1 encodes a nucleotide phosphatase that in vitro has inositol polyphosphate 1-phosphatase and 3',(2'),5'-bisphosphate ...

Journal of Integrative Plant Biology, EarlyView.Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

Arenaviridae exoribonuclease presents genomic RNA edition capacity [PDF]
, 2019 AbstractThe Arenaviridae is a large family of viruses causing both acute and persistent infections and causing significant public health concerns in afflicted regions. A “trademark” of infection is the quick and efficient immuno-suppression mediated in part by a 3’-5’ RNA exonuclease domain (ExoN) of the Nucleoprotein (NP).

Direct observation of processive exoribonuclease motion using optical tweezers [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Bacteria regulate the synthesis and degradation of RNA molecules to ensure timely and robust responses to an ever-changing environment. The transcript’s lifetime can be influenced profoundly by a secondary structure that can form in the RNA and that may inhibit or promote its digestion by RNases.

The Exosome Subunit Rrp44 Plays a Direct Role in RNA Substrate Recognition [PDF]
, 2007 The exosome plays key roles in RNA maturation and surveillance, but it is unclear how target RNAs are identified. We report the functional characterization of the yeast exosome component Rrp44, a member of the RNase II family.

Glia, Volume 74, Issue 5, May 2026.ZSWIM8, an E3 ubiquitin ligase that broadly targets IDR‐rich proteins, drives MiR‐7‐dependent AGO2 degradation and the turnover of many RBPs. Loss of ZSWIM8 leads to MiR‐7 accumulation in oligodendrocyte progenitor cells and myelination defects in the developing brain. ABSTRACT Proteostasis of proteins with intrinsically disordered regions (IDRs) is of

The coronavirus proofreading exoribonuclease mediates extensive viral recombination
PLOS Pathogens, 2020 Recombination is proposed to be critical for coronavirus (CoV) diversity and emergence of SARS-CoV-2 and other zoonotic CoVs. While RNA recombination is required during normal CoV replication, the mechanisms and determinants of CoV recombination are not known.

The 3' to 5' exoribonuclease DIS3: from structure and mechanisms to biological functions and role in human disease [PDF]
, 2015 DIS3 is a conserved exoribonuclease and catalytic subunit of the exosome, a protein complex involved in the 3’ to 5’ degradation and processing of both nuclear and cytoplasmic RNA species.

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation
New Phytologist, Volume 250, Issue 3, Page 1460-1467, May 2026.Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.
