| Nature of the lesion | Statement Reference Insertion of sequences, interrupting Gly 577 of the open reading frame. Insertion of a large block (greater than 1 megabase) of heterochromatin containing AAGAG satellite into the coding region of bw. Insertion of a block of heterochromatin into the bw locus. bw gene is interrupted by sequences that lack tested restriction sites and are likely to be simple sequence repeats characteristic of heterochromatin. | ||

Detailed Description
| |||
Statement Reference Only about 5% of the eye cells are pigmented in bw[D]/+ heterozygous flies. When the polyamide P31 is fed to bwD flies a developmental delay (not seen in wild-type) is observed. This is seen in both heterozygotes and homozygotes, though is more marked in homozygotes. These flies also exhibit a transformation of abdominal segment A6 to A5 and slight roughening of the eye. The addition of P31 enhances the A6 to A5 phenotypes seen in bwD, Ubx1 flies and reduces their viability. Enhances transinactivation of bw caused by Tp(2;2)bw-DX7. Heterozygotes have eyes that are white with a quite uniform scattering of individual reddish spots within ommatidia. Variegation suppressed by extra Y chromosomes. Malpighian tubule colour: bright yellow. dominant position-effect variegation for bw Eye colour: purple to brown; varies with age. Shows slight variegation in combination with st (FBrf0010216). Wings pebbled. | |||

Comments

Using the FISH technique is can be shown that bwD insertion does not affect the pairing or vertical placement of the bw locus, but the insertion of heterochromatin appears to target to bw locus to the nuclear envelope. bwD associates with centromeric satellite sequences in diploid larval tissues. Insertion of satellite DNA at one bw locus causes both gene copies to associate with heterochromatin. The effect of the insertion is a specific association of the bw gene with other heterochromatin on chromosome 2. Whereas this alleles has previously been reported to be revertable (FBrf0007893), recent efforts have shown it to be non-revertable (K. Loughney, unpublished data). Since 1950 some and perhaps all lines of bwD have undergone a secondary event that removed a portion of the coding region of the brown gene, generating a null allele. | |||
