当A组链球菌噬菌体SP24在不相关的宿主菌株CS112上繁殖时,它经历了DNA重排:重排涉及从菌株CS112携带的不相关的内源性原噬菌体替换独特的DNA(2.5kb)。这种替换事件在感染菌株CS112后可重复发生,因为发现来自许多独立分离株的DNA含有相似但不相同的DNA序列。限制性内切酶图谱表明,感染噬菌体和原噬菌体共享的同源序列之间的重组产生了重排。重组噬菌体显示出比野生型SP24噬菌体颗粒更快地吸附到CS112细胞:因此,它在多轮感染期间具有选择性优势。
When the group A streptococcal bacteriophage SP24 was propagated on an unrelated host strain CS112, it underwent a DNA rearrangement: the rearrangement involved a substitution of unique DNA (2.5 kb) from an unrelated endogenous prophage carried by strain CS112. This substitution event occurred reproducibly upon infection of strain CS112, as DNAs from a number of independent isolates were found to contain similar, but not identical, DNA sequences. Restriction endonuclease mapping suggested that recombination between homologous sequences shared by the infecting phage and the prophage produced the rearrangement. The recombinant phage was shown to adsorb more rapidly to CS112 cells than did wild type SP24 phage particles: It therefore has a selective advantage during multiple rounds of infection.
