    ..Because the effect is seen only when a TP was present in the mother's genotype, maternally generated P-element piRNAs could facilitate regulation by the KP repressor polypeptide. ..

    ..In nature, repression by the KP polypeptide may therefore be facilitated by cytotype-mediating piRNAs. ..

    ..Regulation by telomeric P elements appears to be epistatic to regulation by repressor P polypeptides. ..

    ..Cytotype regulation by telomeric P elements may be tied to a system that uses RNAi to regulate the activities of telomeric retrotransposons in Drosophila. ..
