Biologists mapping the human body have long assumed that every major kind of microscopic life inside us already had a place ...

The status of virus and viroid infections in flowering cherry trees (Prunus yedoensis) in prominent ornamental collections in Korea (Seoul, Jinhae, Jeju) and the U.S. (Washington, D.C.) was ...

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 ...

A viroid that several scientists call "the biggest concern for cannabis and hop growers worldwide," is in Michigan. Called hop latent viroid (HLVd), the viroid, a tiny infectious particle smaller than ...

Biological entities called obelisks have been hiding—in large numbers—inside the human mouth and gut. These microscopic entities, which were recently discovered by a team at Stanford University, are ...

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 ...

We may have an adequate understanding of the human body in that, well, we invented aspirin and sequenced the genome, but researchers still find out new things about the humble homo sapien all of the ...

A team of researchers has developed a computational pipeline to identify and better understand viroids and viroid-like covalently closed circular RNAs (cccRNAs, also referred to as, simply, circular ...

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 ...
