Transformation of Bacillus subtilis strains carrying the point mutations spoIIA42 or spoIIA69 by a plasmid, pHM2, carrying the spoIIA+ allele gave occasional recombinants in which the plasmid had acquired the chromosomal mutation. Transformation of a spo+ strain by these derivative plasmids gave occasional recombinants in which the chromosome of the recipient had acquired the plasmid-borne spoIIA mutation. Both types of behaviour were recE+-dependent. Mutations spoIIA42 and spoIIA69 fell into a single complementation group.
携带点突变spoIIA42或spoIIA69的枯草芽孢杆菌菌株被携带spoIIA+等位基因的质粒pHM2转化，偶尔会产生重组体，其中质粒获得了染色体突变。用这些衍生质粒转化spo+菌株，偶尔会产生重组体，其中受体的染色体获得了质粒携带的spoIIA突变。这两种行为都依赖于recE+。突变spoIIA42和spoIIA69属于一个单一的互补群。
