Abstract

Adaptive Girdle Loss in Sticklebacks: How do molecular changes give rise to phenotypic adaptation exemplified by the repeated reduction in the pelvic girdle observed in separate populations of sticklebacks? Now Chan et al. (p. 302 , published online 10 December) have identified the specific DNA changes that control this major skeletal adaptation. The key locus controlling pelvic phenotypes mapped to a noncoding regulatory region upstream of the Pituitary homeobox transcription factor 1 gene, which drives a tissue-specific pelvic enhancer. Multiple populations showed independent deletions in this region and enhancer function was inactivated. Reintroduction of the enhancer restored pelvic development in a pelvic-reduced stickleback.

  • Evolutionary changes in any pleiotropically active gene, as are most regulatory genes, will generally target specific cis-regulatory modules.

    “it predicts that evolutionary changes in any pleiotropically active gene, as are most regulatory genes, will generally target specific cis-regulatory modules”

    From Evolution of Gene Regulatory Networks Controlling Body Plan Development (2011) · cites this paper as Chan et al., 2010

    The Discussion reports adaptive change centered on the tissue-specific Pel enhancer rather than the Pitx1 coding region, and ‘A small enhancer drives pelvic expression of Pitx1’ shows that this enhancer acts in one of several tissues where Pitx1 is expressed. This supports Pitx1 as an example, but the paper does not predict that evolutionary changes in any pleiotropic gene will generally target specific cis-regulatory modules, or state that most regulatory genes are pleiotropic.

  • The underlying genomic event for pelvic spine reduction is deletion of a cis-regulatory module controlling pitx1 expression in pelvic buds during larval development.

    “The underlying genomic event turns out to be deletion of a cis-regulatory module which controls expression of the pitx1 regulatory gene in the pelvic buds during larval development (Chan et al., 2010).”

  • The cis-regulatory module lies in an unstable, repetitive sequence-filled genomic region, possibly accounting for its repeated deletion.

  • Introducing the cloned cis-regulatory module upstream of Pitx1 coding sequence into reduced spine fish rescued the spineless phenotype.

    “when this cis-regulatory module was cloned upstream of a sequence encoding the Pitx1 protein and introduced into reduced spine fish, it rescued the spineless phenotype.”

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.
