German Scientists Develop New Agent Against Cucumber Mosaic Virus

Researchers from Martin Luther University in Halle-Wittenberg (Germany) have invented new RNA-based active substances that effectively protect plants from one of the most dangerous viruses in agriculture — the cucumber mosaic virus (CMV). This virus affects over 1200 plant species, including zucchini, cucumbers, cereals, and medicinal crops.

This was reported by the university’s press service.

The scientists created special double-stranded RNA molecules known as edsRNA, which support the natural immunity of plants. After being introduced, these molecules break down into small interfering RNAs (siRNA) that block the virus’s replication. Laboratory tests showed that 80-100% of treated plants survived after infection.

The researchers are also working on making these substances more user-friendly, for example, in the form of a spray. Field trials are planned, although regulatory approval is required for this. However, the team of scientists is confident in the potential of this method. In the USA, the first RNA-based plant protection agent has already been approved, opening new horizons for the implementation of progressive technologies in agriculture.
