Detection of integrated forms of XacF1 after infection in Xcc MAFF 301080 as a host. Cells were infected with wild‐type XacF1 (A) or with a ∆XacF1′ mutant that lacked a 5′ major portion of ORF12, but retained attP (B). Arrows indicate bands corresponding to integrated forms. Lanes: M, molecular marker (lambda‐StyI fragments); 1, 2 h p.i.; 2, 4 h p.i.; 3, 6 h p.i.; 4, 12 h p.i.; 5, 24 h p.i.; 6, 48 h p.i.; 7, 72 h p.i.
