Description

Insertion of a 0.85kb P-element in an intron 6.5kb downstream of the P165 promoter, in the same 5'-3' orientation as the direction of br transcription. Insertion is at position 3011 of cosmid 17A9.

(Gonzy et al., 2002)

0.85kb P-element insertion within a 565bp PstI-ClaI fragment of an intron (399bp downstream from the PstI site and 166bp upstream from the ClaI site), not far downstream of a known promoter (p165), at coordinate 172 of the BRC map (FBrf0044219) in parallel orientation.

(Gonzy-Treboul et al., 1995)

Insertion truncated P element.

      Originally defined as hypomorphic 'l(1)2Bd' allele (FBrf0081422) or as a weak 'l(1)2Bc' allele (FBrf0050541). Mutation fails to complement 'npr' amorphic alleles but does complement strong 'br', 'rbp' or 'l(1)2Bc' alleles or a hypomorphic 'l(1)2Bd' allele.

      Transposase induced revertants fully complement brnpr-6 allele and exhibit a wild type molecular pattern.
