Crop spray gives plants GMO benefits without altering genes
Scientists have developed a clay-based RNA spray that turns off certain genes in plants, making them resistant to a virus for up to 20 days. With a single treatment, the researchers were able to protect tobacco plants from the "pepper mild mottle virus," a serious disease transmitted by humans during farm operations. On top of crop protection, the technique could be used to modify the color, taste and appearance of plants, but unlike with GMO plants, the underlying DNA would not be changed.
