Phylogenetic tree of rice shoot-associated Planctomycetes based on representative sequences of OTUs in clone libraries of 16S rRNA genes. The tree was constructed by the neighbor-joining method. The scale represents 0.05 substitutions per site. The numbers at the nodes are the proportions of 1,000 bootstrap resamplings, and values <50% are not shown. The OTUs described in the main text are indicated in bold.
