Figure 26-3: Physical and genetic map of P4 (panel A) and P4 immunity region (panel B). Coordinates are from the annotated complete nucleotide sequence of P4 (GenBank accession number X51522). Transcription start and termination sites are indicated by bent arrows and hanging open circles, respectively. The arrows beneath the maps in panel A and B indicate the early, late and immune phase transcripts from the two main operons. For other explanations see Table 26-1 and the text.
