For the study, the researchers developed a novel method for identifying key RNA characteristics that can be used to fight Cucumber mosaic virus (CMV), which is a worldwide and deadly plant virus ...

RNA viruses, on the the other hand, are a whole other ball park. Since the viruses' genetic information is derived from RNA, mutations can have a major evolutionary impact on the viruses.

Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study. The researchers were able to fend off a common virus using the ...

They found that the plant viruses all have a protein shell that activates receptors, called toll-like receptors, that are on the surface of immune cells. But what’s unique about cowpea mosaic virus is ...

Scientists at ORNL have developed a first-ever method of detecting ribonucleic acid, or RNA, inside plant cells using a technique that results in a visible fluorescent signal. The technology can ...

Compatible virus–host interactions depend on a suitable milieu in the host cells permitting viral gene expression, replication, and spread. During pathogenesis, viruses hijack the plant cellular ...

Transmission to other plants completes a virus’s life cycle. History The first plant virus to be discovered was found on the leaves of tobacco plants in the late 19th Century.

Antiviral activity and PheoA’s mechanism of action The study results show that PheoA could inactivate RNA viruses such as SARS-CoV-2 by preventing early viral infection in cells.

During a viral infection, the plant’s cells are hijacked by the virus to multiply itself. Key products of this process are viral RNA molecules that serve as blueprints for the production of proteins. ...
