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 ...

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 ...

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 ...

Potato spindle tuber viroid (PSTVd) has a circular non-coding RNA genome of 359 nucleotides that replicates and spreads systemically in host plants. Consequently, all functions needed to establish a ...

Viroids are tiny strands of circular, infectious RNA. They differ from viruses in that they do not have a protective protein coat and that they do not encode any proteins of their own. They are also ...

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, ...

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 ...
