testis | adult stage (with DroncI29)
DroncI29/DroncL32 transheterozygotes exhibit a significant increase in the proportion of hyperplastic testes as compared to controls; these testes exhibit a significant decrease in necrosis at their apical tip (as shown by the number of spermatogonial cysts bearing Propidium Iodine-positive or TUNEL-positive cells), as compared to controls. During spermatogenesis, cystic bulges and waste bags are largely absent and actin investment cones in the individualization complex are uncoordinated, as compared to controls.
NcL32 mutants display severe defects during the spermatid individualization process. The cystic bulges are frequently reduced in size or appear flat due to a failure in the appropriate collection of the cytoplasm of the spermatids . The retained cytoplasm is clearly visualized as a trail along the entire length of what was supposed to have been the post-individualized portion of the spermatids. Frequently a large portion of the spermatid cytoplasm is retained in a 'mini' cystic bulge structure, which often contains part of the individualization complex. Waste bags are also reduced in size.

Both the significant proportion of hyperplastic adult testes and the increased necrosis at the apical tip of the testes observed in DroncI29/DroncL32 transheterozygotes are rescued by the expression of Droncpro.Scer\UAS, Droncpro.C-A.Scer\UAS, DroncΔN.Scer\UAS, or DroncΔN.C-A.Scer\UAS, but not DroncCARD.Scer\UAS, under the control of Scer\GAL4nos.PU. The significant proportion of hyperplastic adult testes is also rescued by the expression of either DroncWT.5'3'UTR or DroncC-A.5'3'UTR.
The sperm individualization defects observed in DroncI29/DroncL32 transheterozygotes are not rescued by the expression of either DroncWT.5'3'UTR or DroncC-A.5'3'UTR.
