We discuss how organisms use light information in a way crucial for their development, growth and survival: phototropism, phototaxis, photoperiodism, and synchronization of circadian clocks.

One of the regulatory mechanisms involved in these responses is phototropism, which allows plants to change their growth direction in response to the location of the light source.

Disruption of phototropism, phototaxis, photoperiodism, and circadian clock synchronization underlies much of the disruptive effects of artificial light at night.

We discuss how organisms use light information in a way crucial for their development, growth and survival: phototropism, phototaxis, photoperiodism, and synchronization of circadian clocks. These aspects are treated in depth, as their perturbation underlies much of the disruptive effects of ALAN.
The molecular mechanisms underlying Arabidopsis phototropism include phototropin blue light photoreceptors, phototropin signaling components, auxin transporters, and auxin action mechanisms.
The review emphasizes recent progress in elucidating phototropic responses with particular emphasis on mutant phenotypes.
Molecular genetic analyses in Arabidopsis have begun to clarify the molecular mechanisms underlying phototropism.
