We examined the genetic diversity of root nodule bacteria associated with the Australian legume Acacia longifolia in two stages of invasion of a coastal sand dune system. All isolates belonged to the genus Bradyrhizobium. A higher diversity was found in the long-established trees. The results suggest the introduction of exotic bradyrhizobia with the plant.
我们在一个沿海沙丘系统入侵的两个阶段,研究了与澳大利亚豆科植物长叶相思相关的根瘤菌的遗传多样性。所有分离株都属于慢生根瘤菌属。在长期生长的树木中发现了更高的多样性。结果表明,外来慢生根瘤菌是随植物引入的。
