P-element invasions in Drosophila erecta shed light on the establishment of host control over a transposable element
D. Selvaraju, F. Wierzbicki, R. Kofler
This study introduces the P-element into Drosophila erecta to investigate host defense mechanisms against transposable elements, finding that siRNAs initiate defense but activation of the ping-pong cycle is critical for controlling TE spread.
