Cytotype regulation of P transposable elements in Drosophila melanogaster: repressor polypeptides or piRNAs?
The telomeric P elements TP5 and TP6 are associated with the P cytotype, a maternally inherited condition that represses P-element-induced hybrid dysgenesis in the Drosophila germ line. To see if cytotype repression by TP5 and TP6 might be mediated by the polypeptides they could encode, hobo transgenes carrying these elements were tested for expression of mRNA in the female germ line and for re...
متن کاملCytotype Regulation by Telomeric P Elements in Drosophila melanogaster : Interactions With P Elements From M9 Strains
P strains of Drosophila are distinguished from M strains by having P elements in their genomes and also by having the P cytotype, a maternally inherited condition that strongly represses P-element-induced hybrid dysgenesis. The P cytotype is associated with P elements inserted near the left telomere of the X chromosome. Repression by the telomeric P elements TP5 and TP6 is significantly enhance...

متن کاملTelomeric P elements associated with cytotype regulation of the P transposon family in Drosophila melanogaster.
P elements inserted at the left end of the Drosophila X chromosome were isolated genetically from wild-type P strains. Stocks carrying these elements were tested for repression of P-strain-induced gonadal dysgenesis in females and for repression of transposase-catalyzed P-element excision in males and females. Both traits were repressed by stocks carrying either complete or incomplete P element...
متن کاملEstablishment and maintenance of the P cytotype associated with telomeric P elements in Drosophila melanogaster.
P elements inserted near the left telomere of the X chromosome are associated with the P cytotype, a maternally transmitted condition that strongly regulates the activity of the P transposon family in some strains of Drosophila. The regulatory abilities of two such elements, TP5 and TP6, are stable in homozygous stocks over many generations. However, these regulatory abilities are attenuated wh...
