A βTub85D promoter drives expression of a fluorescent reporter of phosphatidylinositol 4,5 bisphosphate (PIP2) distribution (composed of EGFP fused to Tag:PH(hPLCD1)).
spermatid & nucleus | supernumerary
Expression of the Hsap\PLCD1βTub85D.T:Avic\GFP-EGFP transgene causes a dramatic cytokinesis defect, with 47.8-72% of spermatids containing multiple nuclei. The majority of the multinucleate cells contain three or four nuclei.
