ESSENTIAL MEIOTIC ENDONUCLEASE 1 is required for chloroplast development and DNA repair in rice
Summary Chloroplast development is fundamental to photosynthesis and plant growth but is sensitive to environmental stress. Chloroplast development and division require genome stability and DNA repair, but the underlying mechanisms have been unclear. Using a forward genetic approach, we identified the striped‐leaf mutant k48 in the rice (Oryza sativa L.

RNA Recognition and Cleavage by the SARS Coronavirus Endoribonuclease
The emerging disease SARS is caused by a novel coronavirus that encodes several unusual RNA-processing enzymes, including non-structural protein 15 (Nsp15), a hexameric endoribonuclease that preferentially cleaves at uridine residues. How Nsp15 recognizes and cleaves RNA is not well understood and is the subject of this study.

Caenorhabditis elegans RIG-I Homolog Mediates Antiviral RNA Interference Downstream of Dicer-Dependent Biogenesis of Viral Small Interfering RNAs. [PDF]
Dicer enzymes process virus-specific double-stranded RNA (dsRNA) into small interfering RNAs (siRNAs) to initiate specific antiviral defense by related RNA interference (RNAi) pathways in plants, insects, nematodes, and mammals.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria
The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.

Characterization of the role of ribonucleases in Salmonella small RNA decay [PDF]
In pathogenic bacteria, a large number of sRNAs coordinate adaptation to stress and expression of virulence genes. To better understand the turnover of regulatory sRNAs in the model pathogen, Salmonella typhimurium, we have constructed mutants for ...

Homodimerisation-independent cleavage of dsRNA by a pestiviral nicking endoribonuclease [PDF]
AbstractThe glycoprotein Erns plays a central role in the biology of the pestivirus bovine viral diarrhea virus (BVDV). This soluble endonuclease mediates the escape from an interferon (IFN) response in the infected fetus, thereby permitting the establishment of persistent infection. Viral single-stranded (ss) and double-stranded (ds) RNA act as potent

Abstract Since the emergence of SARS‐CoV‐2 at the end of 2019, the virus has caused significant global health and economic disruptions. Despite the rapid development of antiviral vaccines and some approved treatments such as remdesivir and paxlovid, effective antiviral pharmacological treatments for COVID‐19 patients remain limited. This study explores

Identification of Small‐Molecule Inhibitors of the XendoU Endoribonucleases Family [PDF]
AbstractThe XendoU family of enzymes includes several proteins displaying high sequence homology. The members characterized so far are endoribonucleases sharing similar biochemical properties and a common architecture in their active sites. Despite their similarities, these proteins are involved in distinct RNA‐processing pathways in different ...
