Comments

The 3L:26014112..27157999 release 6 coordinates of the left breakpoint are estimates. The left extent corresponds to the right end of CG40178, which Marchant & Holm (FBrf0048227) say is not deleted. The right extent corresponds to the right end of vtd, which Marchant & Holm (FBrf0048227) say is deleted.

The 3L:27967244..28112227 release 6 coordinates of the right breakpoint are estimates. The left extent corresponds to the left end of CG17514, which Marchant & Holm (FBrf0048227) say is deleted. Because Df(3L)2-66 extends into centric heterochromatin according to Marchant & Holm (FBrf0048227), the right extent is shown arbitrarily as the right end of chromosome 4 genome assembly.

Comments on Cytology

At least a major portion of h50 is absent in this deficiency. It is not clear whether or not h49 and h51 are affected.

Left limit of break 1 from non-inclusion of l(3)80Fg (FBrf0048227) Right limit of break 1 from inclusion of vtd (FBrf0048227) Left limit of break 2 from inclusion of vtd (FBrf0048227) Right limit of break 2 from polytene analysis (citation unavailable)

The Df(3L)2-66 chromosome may 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), but the eye colour phenotype in the presence of Df(3L)2-66 overlaps the eye colour phenotype in a wild-type background so it cannot be unequivocally demonstrated that the deficiency chromosome uncovers a suppressor of telomeric silencing.
