Construct: Compensatory nucleotide substitutions in stem-loop III of the nos TCE sequences, that are predicted to restore base pairing.
80% of embryos derived from nosBN females that are also carrying nosTCE.IIIA:U have anterior defects.
nanosTCE.IIIA:U rescues nanosBN
nosTCE.IIIA:U rescues the abdominal segmentation defect of embryos derived from nosBN females; 100% of embryos have 7-8 abdominal segments.
