Planctomycetes: Cell Structure, Origins and Biology

Abstract

Whole-genome sequencing has become a powerful and informative approach for determining the genetic basis of known bacterial properties, predicting new properties, and enabling post-genomic tools. However, genome sequencing and annotation are most useful in the context of comparative genomic and evolutionary analysis, which allows the determination of phylogenetic relationships between extant organisms, provides insights into the evolution of different biological systems, and sheds light on processes accounting for organismal diversity. Genome sequence information is currently available for 20 species of Planctomycetes, Verrucomicrobia, and Lentisphaerae as well as for a number of chlamydial species. In this chapter, we show how this information can be employed to infer molecular mechanisms underlying important ecological, physiological, and evolutionary characteristics of these bacteria and address general questions regarding mechanisms of genome evolution in the PVC superphylum.
