Construct: Insertion of a C residue at position 72 (coordinate of nucleotide insertion is relative to the start of the nos 3' UTR sequences) in stem-loop III of the nos TCE sequences.

nanos^{TCE.IIIA:U^C72} partially rescues nanos^BN

nos^{TCE.IIIA:U^C72} partially rescues the abdominal segmentation defect of embryos derived from nos^BN females; 5% of embryos have no abdominal segments, 34% have 1-3 abdominal segments, 55% have 4-6 abdominal segments and 6% have 7-8 abdominal segments.
