Characterization of Planctomyces limnophilus and Development of Genetic Tools for Its Manipulation Establish It as a Model Species for the Phylum Planctomycetes

Abstract
Planctomycetes represent a remarkable clade in the domain Bacteria because they play crucial roles in global carbon and nitrogen cycles and display cellular structures that closely parallel those of eukaryotic cells. Studies on Planctomycetes have been hampered by the lack of genetic tools, which we developed for Planctomyces limnophilus .
