DOI: 10.1016/j.pbi.2017.03.018
Abstract: Cyanobacteria are able to move directly towards or away from a light source, a process called phototaxis. Recent studies have revealed that the spherical unicellular cyanobacterium Synechocystis sp. PCC 6803 exhibits a cell polarity in… read more here.

DOI: 10.1038/s41567-018-0277-7
Abstract: Biological microswimmers exhibit versatile strategies for sensing and navigating their environment, such as run-and-tumble and curvature modulation. Here, we report a striking phototactic behaviour of the microswimmer Euglena gracilis, where these eukaryotic cells swim in… read more here.

DOI: 10.1093/pcp/pcw218
Abstract: The Synechocystis sp. PCC6803 can move on a solid surface in response to light, a phenomenon called phototaxis. Although many of the photoreceptors involved in phototaxis have been identified, the mechanisms that regulate directional motility… read more here.

DOI: 10.1103/physreve.107.014404
Abstract: A fundamental issue in biology is the nature of evolutionary transitions from unicellular to multicellular organisms. Volvocine algae are models for this transition, as they span from the unicellular biflagellate Chlamydomonas to multicellular species of… read more here.

DOI: 10.1128/aem.00196-22
Abstract: Optimizing light absorption is of paramount importance to photosynthetic organisms. Some photosynthetic microbes have evolved a sophisticated process called phototaxis to move toward or away from a light source. ABSTRACT Phototrophic biofilms in most environments… read more here.

DOI: 10.2139/ssrn.4120179
Abstract: Cyanobacteria respond to light stimulation, activating localized assembly of type IV pili for motility. The resulting phototactic response is highly dependent on the nature of the incoming light stimulus, and the final motility parameters depend… read more here.

DOI: 10.7554/elife.73405
Abstract: Many cyanobacteria, which use light as an energy source via photosynthesis, show directional movement towards or away from a light source. However, the molecular and cell biological mechanisms for switching the direction of movement remain… read more here.
