Description

Genomic nanos fragment in which the nanos 3'UTR has been replaced with the αTub84B 3'UTR. One copy of a +2 element from the nanos 3' UTR with a mutation in the +2' region is inserted within the αTub84B 3' UTR sequences. A Tag:HA epitope has been inserted at the 5' end of the nanos coding region.

      Fails to rescue

      nanosnanos.+2A.Tag:HA fails to rescue nanosBN

      (Bergsten et al., 2001)
      Comments

      nosnos.+2A.T:Ivir\HA1 fails to rescue the abdominal segmentation defect of embryos derived from nosBN females; 92% of the embryos develop no abdominal segments and 8% develop 1-3 abdominal segments.
