Structural studies of planctomycete Gemmata obscuriglobus support cell compartmentalisation in a bacterium.

Members of phylum Planctomycetes have been proposed to possess atypical cell organisation for the Bacteria, having a structure of sectioned cells consistent with internal compartments surrounded by membranes. Here via electron tomography we confirm the presence of compartments in the planctomycete G...
