Cover Story: Type IV pili (T4P) are cell-surface proteinaceous filaments found in many prokaryotic organisms and convey twitching motility through their extension/retraction cycles, moving cells across surfaces. In cyanobacteria, twitching motility is the sole mode of motility characterised to date and is how cells perform phototaxis, the movement towards and away from directional light sources. Wavelength and intensity of light determine the direction of movement and signal for some cyanobacteria to form multicellular assemblages. Formation of such aggregates allows for acclimation to unfavourable environmental conditions and stresses. T4P also enable natural transformation and secretion processes. Thus, cyanobacteria respond to external stimuli by escaping unfavourable environmental conditions via phototaxis, exchanging genetic material, or modifying their surroundings to better fit their needs.

Function and Benefits of Natural Competence in Cyanobacteria: From Ecology to Targeted Manipulation

  • Alexandra M. Schirmacher,
  • Sayali S. Hanamghar and
  • Julie A. Z. Zedler

22 October 2020

Natural competence is the ability of a cell to actively take up and incorporate foreign DNA in its own genome. This trait is widespread and ecologically significant within the prokaryotic kingdom. Here we look at natural competence in cyanobacteria,...
