Heat shock causes generation of supernumerary pole cells but these cannot be detected after stage 14 embryos when the pole cells coalesce in the embryonic gonad. Hoescht-staining demonstrates a large number of the pole cells fall through the somatic cell layer, lose their plasma membrane and leave behind a mass of chromatin. The resulting embryos develop into morphologically normal fertile adults. Over expression in early embryos leads to a distinct nuclear morphology and earlier onset of mitotic asynchrony of the pole bud nuclei.
gclHsp83.PJ rescues gclrev390
Addition of this construct to flies homozygous for Df(2R)cmp44E-rev390, also carrying one copy of cmp44E+t8.5, rescues the maternal effect pole cell and pole bud phenotypes seen in these flies.
Overexpression of gcl in the germline.
