Figure 1From: The spontaneously produced lysogenic prophage phi456 promotes bacterial resistance to adverse environments and enhances the colonization ability of avian pathogenic Escherichia coli strain DE456Morphological 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.Back to article page
