| ultrastructure of free-living and nitrogen-fixing forms of rhizobium meliloti as revealed by freeze-etching. | freeze-etching of rhizobium meliloti provided considerable insight into the ultrastructure of this bacterium and into the changes accompanying the transformation from the free-living rod forms to the nitrogen-fixing bacteroid forms. in the small rods, one cleavage plane was revealed at the level of the cell wall and a second at the level of the plasma membrane. very little structure was evident at the cell wall level, but distinctly different convex and concave fracture faces were exposed at the ... | 1973 | 4688143 |
| on the question of crown-gall tumor initiation by dna of bacteriophage ps8. | dna of agrobacterium tumefaciens bacteriophage ps8 was isolated by using several procedures. whole phage and phage dna were tested for tumor-inducing ability on 10 species of plants with various additions to assist such activity. the reported tumorigenicity of phage ps8 dna could not be confirmed, and no evidence to implicate phage ps8 involvement in tumor initiation was obtained. | 1973 | 4688706 |
