The expression of Su(H)Scer\UAS.T:Hsim\VP16 under the control of either Scer\GAL4pnt-14-94 or Scer\GAL4insc-Mz1407 leads to a severe increase in the number of neuroblasts per third instar larval brain lobe, as compared to controls.

Expression of Su(H)Scer\UAS.T:Hsim\VP16 under the control of Scer\GAL4GMR.PF results in excess mitoses in the eye disc posterior to the morphogenetic furrow. There is also a smaller increase in mitotic figures anterior to the morphogenetic furrow.

When Su(H)Scer\UAS.T:Hsim\VP16 is driven by Scer\GAL4eve.eme, in some segments no eve expressing cells form and in others more eve expressing pericardial cells and no DA1 muscles form.

Expression of Su(H)Scer\UAS.T:Hsim\VP16 under the control of Scer\GAL4byn-Gal4 results in embryos with hindguts that are dramatically shorter and wider than wild type. Expression of Su(H)Scer\UAS.T:Hsim\VP16 under the control of Scer\GAL4455.2 does not affect hindgut elongation, but ectopic hindgut boundary cells are seen. A large portion of the hindgut shows a reversal of left-right looping.

Expression of Su(H)Scer\UAS.T:Hsim\VP16 under the control of Scer\GAL4byn-Gal4 in the embryo results in the entire large intestine differentiating into boundary cells.

Wings from flies expressing Su(H)Scer\UAS.T:Hsim\VP16 under the control of Scer\GAL4ptc-559.1 are distorted by extensive outgrowth that is accompanied by ectopic wing margin structures. When Su(H)Scer\UAS.T:Hsim\VP16 is driven by Scer\GAL4dpp.blk1 an ectopic wing margin is formed, the proximal part of the wing is altered, and the L3 vein is wider.

The increased number of neuroblasts in third instar larval brain lobes resulting from the expression of Su(H)Scer\UAS.T:Hsim\VP16 under the control of either Scer\GAL4pnt-14-94 or Scer\GAL4insc-Mz1407 is fully suppressed by the co-expression of either Cdk9D199N.Scer\UAS.SR or Su(Tpl)HMS00277.

Scer\GAL4GMR.PF-driven co-expression of Su(H)Scer\UAS.T:Hsim\VP16 and DlScer\UAS.cJa results in an expansion of the zone of BrdU incorporation (a marker of S phases) and an increase in the number of cell divisions. Co-expression of Su(H)Scer\UAS.T:Hsim\VP16 and DlScer\UAS.cJa gives the same degree of excess proliferation in the eye disc as expression of Su(H)Scer\UAS.T:Hsim\VP16 alone.

Scer\GAL4GMR.PF-driven expression of Su(H)Scer\UAS.T:Hsim\VP16 is unable to rescue the small size of E2frM729 eye disc clones.
