Summary: DNA contents of different species of broth-cultured Rhizobium bacteria and bacteroids from root nodules were determined by cytofluorometry. In almost all species bacteroids appeared to contain more DNA than the corresponding bacteria. A correlation was found between the DNA content and size of the bacteroid, the latter being influenced by the host plant.
