English: Adsorption of P-SSP7 phage to Prochlorococcus MED4 visualized by cryo-ET.
(a) Slice (~20 nm) through a reconstructed tomogram of P-SSP7 phage incubated with MED4, imaged at ~86 min post-infection, and (b) corresponding annotation highlighting the cell wall in orange, the plasma membrane in light yellow, the thylakoid membrane in green, carboxysomes in cyan, the polyphosphate body in blue, adsorbed phages on the sides or top of the cell in red, and cytoplasmic granules (probably mostly ribosomes) in light purple. FC and EC show full-DNA capsid phage and empty capsid phage, respectively. Scale bar is 200 nm.
