The piRNA pathway is an RNA interference mechanism that represses 'selfish' genetic elements called transposons in Drosophila melanogaster germ cells. Each of the four egg chambers in this image expresses a different piRNA pathway component tagged with GFP (green). The tagged proteins, clockwise from top left, are: Tejas; Aubergine; Krimper and Vasa. The actin cytoskeleton is labeled with rhodamine-phalloidin (red), and DNA with DAPI (blue).
