hide Detailed Description
Statement
Reference
pAbp[k10109]/pAbp[EY11561] heterozygotes exhibit abnormalities in spermatogenesis. these include absence of meiotic cytokinesis (in 5% of cases), resulting in formation of polyploid spermatids and defects in spermatid elongation (in approximately 100% of cases). Nuclei fail to elongate, keep a round shape and are dispersed along the cyst instead of grouping at the head of the cyst. Nebenkern DAPi staining (for DNA) appears to be non-uniform in these mutants, reflecting the effect of the trans-heterozygous mutants on mitochondrial DNA organization in at least 60% of cases. There appears to be no difference between the trans-heterozygous mutant and controls, showing that mutant mitochondrial membranes keep their integrity, but in the mutant, the onion-stage Nebenkern looks larger than in controls, and its morphology differs from a perfect sphere. Examination with an electron microscope reveals abnormal mitochondrial membranes at onion-stage spermatids in the trans-heterozygous mutant. These mitochondria also exhibit defective attachment to axonemes in the elongating spermatids.
pAbp[EY11561]/Df(2R)Pcl7B spermatocytes show defects in meiosis; some spermatocytes have short spindles, and premature separation of centrioles is seen in some cases.
Over-expression of pAbp[EY11561] reduces dendrite branching, and alters dendritic morphology in larval class IV sensory neurons (induced under the control of Scer\GAL4[Act.PU]). Total dendrite length is not significantly reduced in these neurons.
