The spreading of Rhizobium meliloti strains in various autoclaved soils was measured by using simple modifications of established techniques. Behavioral mutants were used to demonstrate that efficient spreading requires active motility and chemotaxis. The rate of spreading was affected by physical or chemical differences among soils and by changes in water content.
采用改良的建立技术来测量根瘤菌在不同灭菌土壤中的扩散。使用行为突变体来证明有效的扩散需要活跃的运动性和趋化性。扩散速率受到土壤物理或化学性质差异以及含水量变化的影响。
