Figure 36-2: Genome organization of temperate phage TP901-1. Sequence is obtained from (23, accession number AF304433). Arrows indicate the size and direction of transcription of open reading frames. Assigned functions are written above the open reading frames. Identified promoters are indicated as small black arrows, while the origin of replication is shown as a black box below the ORFs. Regions of the genome transcribed early, middle, or late in the infection cycle are marked with black lines below the genome.
