Abstract
Complementation tests among previously isolated rex- mutants of bacteriophage lambda reveal that the mutants comprise two complementation groups, designated rexA and rexB. Because rexB- mutants complement prm- mutants, but rexA- mutants do not, it appears that the rexA gene is coordinately controlled with the cI (repressor) gene under the direction of PRM promoter, but that some other promoter is capable of directing the expression of rexB.
摘要
对先前分离得到的噬菌体λ的rex-突变体进行的互补测验表明，这些突变体包含两个互补群，分别命名为rexA和rexB。由于rexB-突变体能与prm-突变体互补，而rexA-突变体则不能，因此似乎rexA基因在PRM启动子的指导下与cI（阻遏物）基因协同控制，但是其他一些启动子能够指导rexB的表达。
