Magnetosensitivity

Drosophila transgenesis for elucidating the precise mechanisms of Cry-mediated magnetosensitivity in insects and also in vertebrates such as migrating birds. can view articles published from 1997 to the current issue. ❋ Robert J. Gegear (2010)

Recently, the radical-pair model involving light-activated photoreceptors as magnetic field sensors has gained considerable support, and the blue-light photoreceptor cryptochrome (CRY) has been proposed as a suitable molecule to mediate such magnetosensitivity. ❋ Unknown (2009)

When the first studies were performed that showed magnetosensitivity of the circadian clock, CRY had not been detected yet and the mechanism of how the clock is influenced by magnetic fields was completely elusive. ❋ Unknown (2009)

Since the radical-pair mechanism of magnetosensitivity depends on the activation of the relevant photopigment by light, it is wavelength dependent. ❋ Unknown (2009)

Drosophila's clock, we aimed to test the role of CRY in magnetosensitivity of the circadian clock. ❋ Unknown (2009)

Such singlet-triplet intersystem crossing is a natural feature of many photochemical reactions that, in fact, may have nothing to do with magnetosensitivity and is the result of the system reaching the most energetically favorable state subsequent to absorption of photon energy. ❋ Unknown (2009)

The fruit fly Drosophila melanogaster is best suited to reveal a putative role of CRYs in the magnetosensitivity of the circadian clock, because there is only one CRY, and because mutants are available that either knock out the binding domain of the FAD ( ❋ Unknown (2009)
