摘要：

Tn5 mutants of Rhizobium meliloti L5.30 defective in motility (Mot-) were isolated and compared to the parent with respect to the nodulation activity. Each of the mutants was able to generate normal nodules on the alfalfa (Medicago sativa) but had slightly delayed nodule formation. Coinoculation of lucerne with wild type Mot+ and Mot- cells in the wide range of ratios resulted in nodules occupied in the majority by a motile strain suggesting that motility is a factor involved in the competition for nodule formation.
