title: Fly antiviral RNA silencing and miRNA biogenesis claim ARS2.
abstract: In plants and invertebrates, small silencing RNAs function in antiviral defense and developmental patterning through pathways that were so far considered genetically distinct. In a recent issue of Cell, Sabin and colleagues report the identification of Drosophila Ars2, a protein required for both these small RNA-mediated functions.
