A set of ~800 largely isogenic deficiency stocks created by FLP-induced recombination between FRT-carrying transgenic insertions; molecularly defined deletion endpoints correspond to initial location of the progenitor insertions. Designed to fill gaps in deletion coverage and breakpoint placement; also used to replace older available deficiencies that have not been molecularly mapped.
Breakpoint from FlyBase's release 5 sequence location of progenitor insertion.
In Df(3R)BSC547 homozygous embryos show variable phenotypes, which may include: germ-band retraction and/or dorsal closure fail, but the musculature is mostly present; pharynx musculature is present, but most other musculature is missing; nothing besides the dorsoventral axis is recognizable.
Df(3R)BSC547 heterozygous adults previously entrained under 12h:12h light:dark cycles exhibit a significant decrease in the proportion of individuals exhibiting circadian rhythmicity upon shift to constant darkness conditions, despite exhibiting an apparently normal circadian period, as compared to controls.
