Isolation and Characteristics of Bacteria in the Nodule Structure from Podocarpus macrophyllus
罗汉松根瘤内生细菌的分离和特性

One bacteria endophyte were isolated from the root nodules of Podocarpus macrophyllus(Thunb.)D.Don.The bacteria has the ordinary characteristics of Rhizobium of leguminous plants after indentification.It made nodulation on its host after inoculation strains.So did on Podocarpus nagi(Thunb.)zoll.et Mor.ex Zoll. seedling which is of the same family and genus with Podocarpus macrophyllus(Thunb.)D.Don.Both strain and host seeding have C 2H 4 reduction activity.But it can not made nodulation on 11 kind of offering tests of leguminous plants after inoculation strains.According to its characteristics the bacteria thus appears to be a member of a disinct Rhizobium lineage.Its phylogenetic relationship position remain to be research.
