Abstract

RNA interference (RNAi) has been shown to spread from cell to cell in plants and in Caenorhabditis elegans, but it does not spread in other organisms, such as Drosophila. A recent report demonstrates that a membrane channel, encoded by the gene sid-1, is responsible for the spreading of RNAi between cells.
