When compared with kds301 ( lexa + ) , xe ( lexa - ) cells showed quite similar levels of survival curve to y - irradiation and mmc , indicating lexa gene had no effect on radiation resistance of deinococcus radiodurans . deinococcus radiodurans " lexa had no revelance with its extremely radioresistance . the recombinant plasmid pza172 was constructed by cloning the lexa gene of deinococcus radiodurans into the vector plasmid puc19 in the downstream of lacz promoter
对lexa基因突变体xe的研究表明，其辐射抗性与lexa基因野生型的抗辐射菌kd8301相近，存活曲线上均显示有一个宽大的肩区，结果发现lexa基因的突变并没有改变抗辐射菌的独特抗性，说明lexa基因与辐射抗性无关。
