Construct: Nucleotide substitutions in stem-loop II of the nos TCE sequences, that are predicted to disrupt base pairing within the stem-loop II helix.
wild-type
embryo | anterior
10% of embryos derived from nosBN females that are also carrying nosTCEIIU have anterior defects.
nanosTCEIIU rescues nanosBN
nosTCEIIU rescues the abdominal segmentation defect of embryos derived from nosBN females; 100% of embryos have 7-8 abdominal segments.
