Botrytis cinerea [or gray mold is] , a fungal pathogen that can infect… almost every fruit and vegetable…
The findings were just published in the journal Nature Plants.
. . . .
Building on that work… they discovered that… small RNAs can flow from the pathogen to the host and from the host to the pathogen.
Furthermore, they found that B. cinerea is capable of taking up RNA molecules from the environment, which makes it possible to use such external RNAs in fungicidal sprays…
The researchers… found that applying those pathogen gene-targeting RNA molecules to the surface of fruits and vegetables… can control gray mold diseases.
…Currently, fungicides and chemical spraying are still the most common disease control strategy. But, these treatments pose serious threats to… environments. RNA… doesn’t present problems for human health and it naturally degrades in soil.
