Figure 4.

The phage comparative genome circle map of 25 strains of the genus Felixounavirus. From the inner circle to the outer circle are GC content, GC skew, reference genome SPJ41, and the phages of the genus Felixounavirus. The outermost circle is the functional annotation: red, cell lysis module; gray, hypothetical protein; orange, DNA replication/modification/regulation; green, phage structure; blue, DNA packaging; and purple, phage–host interactions. The red arrows are functional protein difference regions.
