| Abstract: | In deoxyribonucleic acid of Rhizobium trifolii centrifuged in cesium chloride-ethidium bromide equilibrium was found a sattelite peak containing covalently closed circular deoxyribonucleic acid. The plasmid had a molecular weight of about 64 x 10(6) shown by sedimentation in sucrose gradients and electron microscopy. |
