Phase-plate TEM imaging of a cyanophage virus assembling inside marine cyanobacteria. a) Sectional overview of a late-stage infected Syn5 including labeled cellular components and phages: carboxysomes (C), infecting phages (I), ribosomes (R) and thylakoid membranes (T). b–e) Higher-magnification views of sections and their corresponding 3D reconstructions of cellular components of thylakoid membrane (green) (b); carboxysome (blue) (c); ribosome (purple) (d); A Syn5 cyanophage (red) (e) on the cell’s surface during infection. Yellow: cell envelope; magenta: phage progeny. Scale bars: 50 nm (b,c); 60 nm (d,e). Reproduced with permission.[230] Copyright 2013, Nature Publishing Group.
