Abstract

Degrees of Darkness: Fruit flies in Africa have a tendency to be darker, the higher the altitude at which they live, because melanization offers a selective advantage. The dark pigmentation seen in some populations of Ugandan Drosophila melanogaster is owing to a lack of expression of the ebony gene, and expression results in yellow cuticle. Rebeiz et al. (p. 1663 ; see the News story by Pennisi ) show that mutations in cis regulatory elements, rather than in the coding region, are responsible for the dark color. A series of five mutations in a modular enhancer element influences the level of ebony expression: Three mutations already existed in fly populations with light cuticle color and a further two, more recently acquired dark-specific substitutions, together have created an allele of large effect, which has been swept to high frequency in this population of flies.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Recent studies of Drosophila species have revealed cis-regulatory sequence microevolution underlying adaptive external trait variation.

    “Recent studies that focused on the adaptive evolution of external traits in and among Drosophila species have revealed processes of cis-regulatory sequence microevolution.”

    From Evolution of Gene Regulatory Networks Controlling Body Plan Development (2011) · cites this paper as Rebeiz et al., 2009

  • Cis-regulatory changes affecting yellow and ebony expression account for pigmentation pattern variation in Drosophila.

    “Such processes account for variation in pigmentation patterns due to regulatory changes affecting expression of the yellow differentiation gene (Gompel et al., 2005; Rokas and Carroll, 2006); and the ebony differentiation gene (Rebeiz et al., 2009).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
