A Modified Cas9 Scaffold Allows Extension of the Virus‐Induced Gene Editing Technology to the Large Potyvirus Genus

open access: yesPlant Biotechnology Journal, Volume 24, Issue 8, Page 4933-4947, August 2026.
ABSTRACT Plant viruses are recognized as rapid and effective vectors to deliver CRISPR‐Cas reaction components into plants, a strategy termed virus‐induced gene editing (VIGE). However, VIGE is limited by the host range of the viral vectors. Development of new viral vectors to target a broad range of plant species will potentially enable the delivery ...

A Selected Ribozyme Catalyzing Diverse Dipeptide Synthesis [PDF]

open access: yes, 2002
The sequence of events by which protein, RNA, and DNA emerged during early biological evolution is one of the most profound questions regarding the origin of life.

How physiology solves the gene‐centric impasse

open access: yesExperimental Physiology, Volume 111, Issue 8, Page 3546-3556, 1 August 2026.
Abstract The criteria for distinguishing between association and causation in studies of genes and function are clarified. Genomic association scores alone cannot satisfy those criteria, which is why treatment of common diseases has not benefitted from the cures expected when the Human Genome Project was launched.

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

open access: yesAdvanced Science, Volume 13, Issue 42, 28 July 2026.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Quantitation of In Vitro Activity of Synthetic Trans-Acting Ribozymes Using HPLC

open access: yesBioTechniques, 1997
The cleavage activity of synthetic ribozymes needs to be characterized by reliable and rapid methods. A chromatographic method to simultaneously quantitate the amounts of substrate, cleavage fragments and ribozyme is described.

A recombinase-activated ribozyme to knock down endogenous gene expression in zebrafish.

open access: yesPLoS Genetics
Precise regulation of gene expression is essential to understand a wide range of biological processes. Control over gene expression can be achieved using site-directed recombinases and endonucleases whose efficiency is variable and dependent on the ...

Exonuclease Ribozyme Encoded in a Circular Genome: On the Initiation of the RNA World

open access: yesLife
The “RNA World” hypothesis posits a reasonable scenario for the origin of life. A question central to this scenario is: which RNA species may have emerged as the first ribozyme, thereby initiating the earliest stage of life?

RNase footprinting demonstrates antigenomic hepatitis delta virus ribozyme structural rearrangement as a result of self-cleavage reaction

open access: yesBMC Research Notes, 2008
Background Hepatitis delta virus (HDV) is a satellite virus of hepatitis B. During viral replication the 1700-nucleotide-long genomic RNA and its complement, the antigenomic RNA, undergo self-cleavage catalyzed by internal ribozyme motifs that are ...

Analysis of Self-Cleaving Ribozyme Transition States [PDF]

open access: yes, 2019
Endonucleolytic ribozymes, non-coding RNA molecules capable of self-scission, have been studied for decades. First, because of their novel functionality, and later because their capacity to serve as paradigmatic model systems of RNA catalysis.
