The effect of a virulent bacteriophage on the competitive behaviour of paired strains of Rhizobium trifolii in the root zone of clover plants was examined. The presence of bacteriophage reduced the population density of susceptible strains on the root surface and, in nodulation, favoured resistant or even partially resistant strains which were otherwise less able to form nodules. These effects occurred with different growth temperatures, host species, and ratios of strains in the inoculum.
研究了一种烈性噬菌体对三叶草植物根区配对的三叶草根瘤菌菌株竞争行为的影响。噬菌体的存在降低了根表面敏感菌株的种群密度，在结瘤方面，有利于抗性甚至部分抗性菌株，否则这些菌株形成根瘤的能力较弱。这些影响在不同的生长温度、宿主物种以及接种物中菌株比例的情况下均会出现。
