Construct: +2' element sequences from the nos 3' UTR have been inserted downstream of the +1 element within the αTub84B 3' UTR sequences present in nosnos.+1.Hsp83. As a result, the +1 and +2' sequences are separated by 130bp of αTub84B 3' UTR sequence.
Embryos derived from nosBN females which are also expressing nosnos.+1.+2' do not have anterior defects.
nanosnanos.+1.+2' is a non-suppressor of embryonic abdominal segment phenotype of vas1/vas3
nosnos.+1.+2' fails to rescue the abdominal segmentation defect of embryos derived from vas1/vas3 females; 100% of the embryos develop no abdominal segments. The embryos do not have anterior defects.
nosnos.+1.+2' rescues the abdominal segmentation defect of embryos derived from nosBN females; 6% develop 4-6 abdominal segments and 94% develop 7-8 abdominal segments.
