    What's a GeneRIF?
    1. These findings shed light on distinct and collaborative requirements of Yb and Armi in transposon-targeting piRNA biogenesis.

      Title: Requirements for multivalent Yb body assembly in transposon silencing in Drosophila.
    3. We conclude that transcripts bound by Armi and Yb are identified as piRNA precursors, resulting in localization to cytoplasmic processing granules and their subsequent engagement by the resident piRNA biogenesis machinery.
