Cyanobacterial-Plant Symbioses

  • Reference work entry
The Prokaryotes

Introduction

Cyanobacteria are unique in the wide range of symbiotic associations they form with eukaryotic hosts including plants, fungi, sponges and protists (for reviews, see Adams [2000], Rai et al. [2000], Rai et al. [2002b], and Bergman et al. [2003]). Cyanobacteria are photoautotrophs, and in many cases facultative heterotrophs and nitrogen fixers, and can provide nonphotosynthetic hosts with both nitrogen and carbon. Even if the benefit to the host is clear, that to the cyanobacteria is less obvious. They often receive carbon from photosynthetic hosts, but they are capable of carbon fixation themselves. Perhaps a more likely advantage is protection from predation and from environmental extremes, such as high light intensity and desiccation, in the enclosed environment provided by the host.

The cyanobacterial symbionts of plants all possess at least two essential characteristics—the ability to differentiate heterocysts, which are specialized nitrogen-fixing cells (for a review,...
