Functional gene maps of phages HX1 (a), MYY9 (b), and TH15 (c) prepared using SnapGene software. The different-colored arrows show the CDSs of the phages and their transcription direction. The putative products of each CDS were predicted and divided into four modules, including putative structural proteins, nucleotide metabolism proteins, putative lytic enzymes, and proteins with hypothetical function.
