摘要
Using Tn5 mutagenesis of lysogenic Sinorhizobium meliloti strain L5-30 (phiL54), three neomycin-resistant transconjugants differing in phage-resistance profiles were isolated. Two of them increased the dry weight of plants and were capable of establishing root nodules, whereas the third one was ineffective. The bacterium-phage interaction did not have observable consequences in the Medicago sativa-S. meliloti symbiosis because it did not affect the number of nodules on M. sativa or plant dry weight.
