Morphological characteristics and comparative genomic analysis of phi456. A phi456 forms tiny and blurry plaques on MC1061 in the plaque assay, which are indicated by black arrows. B Transmission electron microscopy images of purified phage phi456. C The structure of prophage phi456. Phi456 showed a 70% nucleotide sequence identity with Escherichia phage RCS47. The unbroken line indicates the length of the sequence, while ORFs classified in the same functional categories are color-coded accordingly.
