Most embryos expressing taccTD.Scer\UAS.P\T.T:Sjap\GST under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 fail to develop. The embryos are often filled with microtubules that are organised into asters which are centered around aggregates of taccTD.Scer\UAS.P\T.T:Sjap\GST protein.
Asters of microtubules are not detected in mutant embryos expressing taccTD.Scer\UAS.P\T.T:Sjap\GST under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 in a mspsMJ15 background. The embryos do not develop, but the male and female pronuclei seem to be in a mitotic state, with spindle-like structures organised around the condensed chromosomes.
