title: Co-localisation of membranes and actin in growing infected cells of Glycine max root nodules.
abstract: The root nodule of Glycine max (L.) Merr. is almost spherical at maturity, and its central tissue consists of infected cells filled with numerous symbiosomes containing bacteroids, interspersed with uninfected cells. During the growth of the nodule, the volume of each infected cell and the number of bacteroids per cell increases, and thus abundant membranes are required for the proliferation of symbiosomes. In expanding infected cells, there are areas adjacent to the nucleus that are devoid of bacteroids, but these areas are filled with numerous membranes and actin filaments, surrounded by endoplasmic reticulum membranes, indicating a perinuclear reservoir of newly formed membranes and a role for actin in delivering membranes to proliferating symbiosomes.
