Females in which vtdαTub84B.T:Avic\GFP-EGFP is the sole source of vtd protein (carrying vtdαTub84B.T:Avic\GFP-EGFP in a vtdex3 background) show premature synaptonemal complex disassembly in egg chambers after proteasomal degradation of the vtd550TEV.tub.T:Zzzz\TEV.CS,T:Hsap\MYC protein induced by expression of slmbScer\UAS.P\T.T:Zzzz\vhhGFP4 under the control of Scer\GAL4nos.PG.
