Abstract
Cyanobacteria are a morphologically diverse and widespread group of phototrophic bacteria, many of which are capable of nitrogen fixation. They form symbioses with a wide range of eukaryotic hosts including fungi (lichens and Geosiphon pyriformis), diatoms, dinoflagellates, sponges, ascidians (sea squirts), corals and plants. The best understood are the plant symbioses, which are the subject of this chapter. In the cyanobacteria–plant associations, the cyanobacteria provide the host with fixed nitrogen and usually adopt a heterotrophic form of nutrition, using fixed carbon supplied by the plant, enabling them to occupy regions of the host, such as the roots, that receive little or no light. Most cyanobacterial symbionts of plants belong to the genus Nostoc, members of which fix nitrogen in specialised cells known as heterocysts, which provide the necessary microoxic environment for the functioning of the oxygen-sensitive enzyme nitrogenase. These cyanobacteria, which are immotile for most of their life cycles, produce specialised motile filaments known as hormogonia, as a means of dispersal and as the infective agents in plant symbioses. Host plants improve their chances of infection by releasing external chemical signals that both stimulate hormogonia formation and serve as chemoattractants. However, within the symbiotic tissue the plant releases hormogonia-repressing factors to ensure the conversion of hormogonia into heterocyst-containing, nitrogen-fixing filaments.
