Retinal cryptochrome in a migratory passerine bird: a possible transducer for the avian magnetic compass

Möller, Andrea, Sagasser, Sven, Wiltschko, Wolfgang, Schierwater, Bernd·2004·Naturwissenschaften

Abstract

The currently discussed model of magnetoreception in birds proposes that the direction of the magnetic field is perceived by radical-pair processes in specialized photoreceptors, with cryptochromes suggested as potential candidate molecules mediating magnetic compass information. Behavioral studies have shown that magnetic compass orientation takes place in the eye and requires light from the blue-green part of the spectrum. Cryptochromes are known to absorb in the same spectral range. Because of this we searched for cryptochrome (CRY) in the retina of European robins, Erithacus rubecula, passerine birds that migrate at night. Here, we report three individually expressed cryptochromes, eCRY1a, eCRY1b, and eCRY2. While eCRY1a and eCRY2 are similar to the cryptochromes found in the retina of the domestic chicken, eCRY1b has a unique carboxy (C)-terminal. In light of the 'radical-pair' model, our findings support a potential role of cryptochromes as transducers for the perception of magnetic compass information in birds.

  • Four different types of cryptochrome have been confirmed in the eyes of migratory birds.

    “It seems a logical next step to more complex living creatures, especially since four different types of cryptochrome have been confirmed in the eyes of migratory birds [103] and cryptochromes from the migratory garden warbler form radicals with millisecond lifetimes under the influence of the blue spectral range [104].”

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.
