STARKVILLE, Miss.—A Mississippi State biological sciences faculty member is using a National Institutes of Health grant to explore virus amplification and replication in plants, studying a specific ...

Future Microbiol. 2010;5(3):393-402. While these new findings cement the relationship between the structure and replication of HDV and plant viroid RNAs, they still leave open the question of whether ...

Recent research that links specific pieces of RNA to an infectious organism's duplication and spread could lead the way to the prevention of viroids, pathogens that can kill or damage food crops and ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 78, No. 10, [Part 2: Biological Sciences] (Oct., 1981), pp. 6381-6385 (5 pages) Nucleic acids isolated from ...

This is a preview. Log in through your library . Abstract Viroids are pathogenic agents that have a small, circular noncoding RNA genome. They have been found only in plant species; therefore, their ...

Viroids are unique systems for the study of RNA structure, function and evolution. They are the minimal RNA replicons characterized so far their genome is ten-fold smaller than that the smallest known ...

Viroid replication generates dsRNA intermediates, which are processed by Dicer into 21- to 25-nucleotide siRNAs. These siRNAs are then incorporated into siRNA – ribonuclease complexes (RISC). If the ...

Viroids are closed circles of ribonucleic acid (RNA) that replicate at a very low level using host cell enzymes, since they do not usually encode proteins. The existence of over ten thousand viroids, ...

Obelisks—tiny RNA circles with protein-coding genes—have been found in the human microbiome, revealing a hidden RNA universe ...

COLUMBUS, Ohio – Recent research that links specific pieces of RNA to an infectious organism’s duplication and spread could lead the way to the prevention of viroids, pathogens that can kill or damage ...

This article addresses some of the questions relating to how hepatitis δ virus (HDV), an agent so far unique in the animal world, might have arisen. HDV was discovered in patients infected with ...
