Cyanobacteria are a group of ecologically diverse photosynthetic bacteria. Because niche differentiation is ultimately the product of differences among individuals within populations, understanding the evolutionary origins of this diversity ultimately requires a population genetics perspective. This chapter considers the current state of our understanding of the mechanisms that generate variation in cyanobacteria, the distribution of this diversity and its potential functional importance, with an emphasis on recent work from our laboratory regarding diversity within and among populations of the cosmopolitan, multicellular cyanobacterium, Mastigocladus laminosus. It concludes with an appraisal of the potential to take a population genomics approach to address fundamental questions regarding the nature of adaptive variation and niche differentiation in these microorganisms read more ...
