Comments on Cytology

The left Df(3L)pbl-X1 breakpoint lies within CTCF or pst or in the region between them, and lies in the range 3L:7349161..7350625 (R5) (predicted cytology: 65F6-65F6).

The right Df(3L)pbl-X1 breakpoint lies within CG7504 or mus301 or in the region between them, and lies in the range 3L:8125230..8134144 (R5) (predicted cytology: 66B7-66B8).

Fails to complement Df(3L)ZP1.

NOT in combination with other aberrations

The size of the tracheal lumen is different to wild type in Df(3L)pbl-X1 embryos.

The Df(3L)pbl-X1 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).

Heterozygosity for Df(3L)pbl-X1 results in 1.3% X chromosome nondisjunction and 0.4% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

Shows dominant enhancement of dominant haltere phenotype caused by Ubx195 and Ubx9.22.

Dominant suppressor of dshhs.sev.B mutant polarity phenotype.

Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

Shows no maternal enhancement of dpphr4.

Deficient embryos show an uninterpretable mutant midgut phenotype.

Other Comments

Used in D.melanogaster/D.simulans hybrids to map at least four non-overlapping regions on the D.simulans 3R that have effects on the species difference of cuticular hydrocarbon profile.
