Maturation of 23S ribosomal RNA requires the exoribonuclease RNase T [PDF]

open access: yesRNA, 1999
Ribosomal RNAs are generally synthesized as long, primary transcripts that must be extensively processed to generate the mature, functional species. In Escherichia coli, it is known that the initial 30S precursor is cleaved during its synthesis by the endonuclease RNase III to generate precursors to the 16S, 23S, and 5S rRNAs.

Degradation of RNA in bacteria: comparison of mRNA and stable RNA [PDF]

open access: yes, 2006
Degradation of RNA plays a central role in RNA metabolism. In recent years, our knowledge of the mechanisms of RNA degradation has increased considerably with discovery of the participating RNases and analysis of mutants affected in the various ...

PPR Protein BFA2 Is Essential for the Accumulation of the atpH/F Transcript in Chloroplasts

open access: yesFrontiers in Plant Science, 2019
As a fascinating and complicated nanomotor, chloroplast ATP synthase comprises nine subunits encoded by both the nuclear and plastid genomes. Because of its uneven subunit stoichiometry, biogenesis of ATP synthase and expression of plastid-encoded ATP ...

The Exosome Subunit Rrp44 Plays a Direct Role in RNA Substrate Recognition [PDF]

open access: yes, 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.

Rex1p Deficiency Leads to Accumulation of Precursor Initiator tRNA\u3csup\u3eMet\u3c/sup\u3e and Polyadenylation of Substrate RNAs in \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e [PDF]

open access: yes, 2009
A synthetic genetic array was used to identify lethal and slow-growth phenotypes produced when a mutation in TRM6, which encodes a tRNA modification enzyme subunit, was combined with the deletion of any non-essential gene in Saccharomyces cerevisiae.

Regulatory Mechanisms of Exoribonuclease PNPase and Regulatory Small RNA on T3SS of Dickeya dadantii

open access: yesMolecular Plant-Microbe Interactions, 2010
The type III secretion system (T3SS) is an essential virulence factor for many bacterial pathogens. Polynucleotide phosphorylase (PNPase) is one of the major exoribonucleases in bacteria and plays important roles in mRNA degradation, tRNA processing, and

Omic characterisation of multi‐component defences against the necrotrophic pathogen Pyrenophora tritici‐repentis in wheat

open access: yesPlant Biology, Volume 27, Issue 3, Page 347-361, April 2025.
Resistance against Tan spot (caused by Pyrenophora tritici‐repentis) in wheat can involve cell wall defences or an absence of susceptibility factors. Abstract Tan Spot disease is caused by the necrotrophic pathogen Pyrenophora tritici‐repentis (Ptr) and poses a significant threat to global wheat production.

Impact of alternative carbon sources and antifungal treatment on Candida glabrata biofilms transcription profile [PDF]

open access: yes, 2016
Candida glabrata is considered a major opportunistic fungal pathogen of humans and has emerged as a leading cause of nosocomial fungal infections. The capacity of this yeast species to cause infections is dependent on the ability to grow within the human

A comprehensive overview on the crosstalk between microRNAs and viral pathogenesis and infection

open access: yesMedicinal Research Reviews, Volume 45, Issue 2, Page 349-425, March 2025.
Abstract Infections caused by viruses as the smallest infectious agents, pose a major threat to global public health. Viral infections utilize different host mechanisms to facilitate their own propagation and pathogenesis. MicroRNAs (miRNAs), as small noncoding RNA molecules, play important regulatory roles in different diseases, including viral ...
