Abstract
Twenty-five rex(-) mutants of phage lambda have been isolated. Three of the mutants, including one amber mutant, map at three distinct sites within the rex region of the lambda genetic map. The existence of the amber mutant provides further evidence that rex and cI are distinct genes, since it seems to be identical to wild-type lambda in its ability to establish or maintain lysogeny.
摘要
已经分离出25种噬菌体λ的rex(-)突变体。其中三个突变体，包括一个琥珀突变体，定位在λ遗传图谱的rex区域内三个不同的位点。琥珀突变体的存在进一步证明了rex和cI是不同的基因，因为它在建立或维持溶原性的能力上似乎与野生型λ相同。
