Abstract
The effect of motility on the competitive success of Rhizobium meliloti in nodule production was investigated. A motile strain formed more nodules than expected when mixed at various unfavorable ratios with either flagellated or nonflagellated nonmotile derivatives. We conclude that motility confers a selective advantage on rhizobia when competing with nonmotile strains.
摘要
研究了运动性对苜蓿根瘤菌在结瘤过程中竞争成功的影响。当一个运动性菌株与有鞭毛或无鞭毛的非运动性衍生物以各种不利比例混合时，它形成的根瘤比预期的更多。我们得出结论，在与非运动性菌株竞争时，运动性赋予了根瘤菌一种选择优势。
