title: Genetic diversity of rhizobia associated with Acacia longifolia in two stages of invasion of coastal sand dunes.
abstract: 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.
