The number of germ cells containing spectrosomes in region I of the germarium is increased compared to wild type to an average of 6.5 cells per germarium in females carrying Otenos.PJ.
Otenanos.PJ is a non-suppressor of female germline stem cell phenotype of DadUASp.cJa, Scer\GAL4VP16.nanos.UTR
Co-expression Otenos.PJ and of DadScer\UAS.P\T.cJa under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 results in the complete loss of germline stem cells in the ovary.
