Modelling Phototaxis as a Collective Phenomenon inCyanobacterial Colonies


Micro-organisms respond to a variety of stimuli, including chemical concentrations, osmolarity and light. Cyanobacteria are a widely distributed, diverse group of photosynthetic bacteria that exhibit phototaxis, or motion in response to light. In the cyanobacterium Synechocystis sp., dense finger-like projections of cells emerging from a colony move towards… (More)
