Description

P{PZ} is inserted behind nucleotide 265 in the 5' untranslated region of the shg transcription unit, such that the Ecol\lacZ coding region is in the opposite orientation to the shg coding region.

Detailed Description
Statement
Reference

7-day old shgR69/+ germaria have normal numbers of germline stem cells (GSCs), but at 63-days old, these germaria have significantly lower GSC numbers and contain significantly fewer cysts than controls, while cap cells are maintained at normal numbers.

Only 8.9% of marked shg10469 somatic stem cells (SSCs) observed during the first week after clone induction in the adult ovary are maintained for 2 more weeks, suggesting that the mutant SSCs are severely destabilised (46% of marked wild-type SSCs observed during the first week after clone induction are maintained for 2 more weeks). Mutant shg10469 oocytes are always localised to the posterior end of the egg chamber.

shg10469 has no dramatic effect on germline stem cell (GSC) maintenance in the ovary; 60% of mutant GSCs observed during the first week after clone induction are maintained for two more weeks (compared to 70% for controls).

Adult escapers show a patterning defect along the anterior wing margin. Mutants show gross disorganization of epithelial tissues in the head, ventral epidermis, Malpighian tubules and tracheal ducts. Malpighian tubule tip cells are present and differentiate into neurons, as in wild type. Tracheal tip cells are also present.

Transposase induced excision is accompanied by reversion of the mutant phenotype.
