| Abstract: | The ultrastructure of young nodules of Robinia pseudoacacia, examined with TEM and SEM. The infected cells of Robinia pseudoacacia nodules contain plentiful infection threads with electrondense matrix insidel. The thread wall encloses the matrix containing a great deal of the invading rhizobia. The rhizobia escape from the unwalled regions of the infection thread or by means of the degradation of the thread wall, subsequently the bacteria become free in the host cytoplasm. |
