Developmental Biology Dicer in RNAi and Development
RNA interference (RNAi) is the process by which double-stranded RNA induces sequence-specific posttranscriptional gene silencing. The enzyme Dicer has been implicated in the generation of short interfering RNAs (siRNAs), which are thought to be the effectors of the gene silencing. Knight and Bass now provide genetic evidence in Caenorhabditis elegans that the ribonuclease III activity of Dicer is important for RNAi in vivo and that mutation of the dicer-1 gene causes sterility. Thus, Dicer seems to have a role in germ line development, or physiology, or both.
