   我们认为在突变体菌株gx217中tn5gusa5所插入的开放阅读框架是一个新的与竞争结瘤有关的基因。
2. Plant assay was performed with the wild - type strain gx201 , the mutant strain gx217 and the function recovered strain rgx217 . the results indicate that the mutant strain gx217 showed a day delay in nodulation time and its abilities of nodule formation efficiency and competitive nodulation were apparently decreased compared with the parental strain gx201 respectively
