Cytological examination of nodules from diploid, tetraploid, and octoploid alfalfa (Medicago sativa L.) plants revealed that the proportion of nodule cells infected by rhizobia was not significantly affected by nuclear ploidy of the host plant. Flow cytometry was used to determine the influence of host plant nuclear ploidy on the nuclear ploidy of infected cells. In nodules from diploid plants, most of the nuclei were tetraploid, whereas in nodules from tetraploid plants, about half of the nodule nuclei were tetraploid and half were octoploid; in octoploid plants, most of the nodule nuclei were octoploid. The occurrence of disomatic nuclei was independent of infection of nodule cells by rhizobia, because diploid plants had mostly disomatic nodule nuclei, and octoploid plants had mostly monosomatic nodule nuclei, whereas all nodules maintained a constant proportion of infected to uninfected cells. These results do not support the earlier hypothesis that infected nodule cells contain disomatic nuclei.
