Gemmata massiliana phylogenetic position amongst other Planctomycetes species. The following Phylogenetic tree shows G. massiliana strain CSUR P189^T position relatively to Gemmata obscuriglobus, to undescribed Gemmata species and to other Planctomycetes. Sequences were aligned using CLUSTALW [39], and phylogenetic inferences obtained using the neighbor-joining method within the MEGA software [40] only bootstrap values ≥95 % are indicated at nodes. T. maritima (M21774) was used as an outgroup. The scale bar represents a 5 % nucleotide sequence divergence
