Expression of Hsap\ORC6[T:Avic\GFP] does not rescue viability in Orc6[35] mutants (that die at the third instar larval stage). Expression of Hsap\ORC6[T:Avic\GFP] results in the release of Orc6[35] mutant cells from G1 arrest, as shown by the ratio of cells containing either 1 or 2 centrosomes being indistinguishable from cells obtained from heterozygous siblings. Chromosomes from neuroblasts isolated from Orc6[35] mutants carrying Hsap\ORC6[T:Avic\GFP] are able to incorporate BrdU, and therefore are able to replicate DNA. b Brains observed in these larvae are significantly reduced in size compared with heterozygous or wild-type larval brains, suggesting severe defects in cell proliferation and larval brain development. Orc6[35] mutant neuroblasts carrying Hsap\ORC6[T:Avic\GFP] accumulate at mitosis. The number of mitotic neuroblasts derived from these transgenic flies increases approximately 2-fold compared with Orc6[35] mutant cells.
