Phototaxis - Wikipedia
网页Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole organism moves towards or away from a stimulus of light. [ 2 ] This is advantageous for phototrophic organisms as they can orient themselves most efficiently to receive light for photosynthesis.
Phototaxis - an overview | ScienceDirect Topics
网页Phototaxis is the process in which an organism alters its motility in response to light stimuli. This phenomenon is widespread in biology, encompassing complex multicellular organisms, unicellular eukaryotes, bacteria, and archaea. Here we will provide an overview of phototaxis in bacteria and archaea (prokaryotes).

网页2020年5月12日 — Phototaxis is the movement of an organism in response to light, whether it goes towards it (positive phototaxis) or away from it (negative phototaxis). It is widespread in the animal kingdom...

网页2009年10月10日 — Phototaxis in the broadest sense means positive or negative displacement along a light gradient or vector. Prokaryotes most often use a biased random walk strategy, employing type I sensory rhodopsin photoreceptors and two-component signalling to regulate flagellar reversal.

网页2016年1月1日 — How could a visual phototactic system evolve into a low-resolution image-forming eye? Image-forming eyes have several properties not found in phototactic eyes, including motion detection, optokinetic response (e.g. to detect a drift in body position in a current), approach-detection (predator detection) or prey following.

Phototaxis: Life in focus | eLife
网页2016年2月9日 — Land plants are restricted to the location in which they germinate and grow, and individual plants are at the mercy of the light conditions where a given seed lands. However, some single-celled photosynthetic organisms exhibit behavior known as “phototaxis” that involves moving in response to local light conditions (Gualteri, 2001).
