title: The effect of RNA synthesis inhibitors on prenucleolar bodies.
abstract: Inhibition of RNA synthesis prevents the fusion of prenucleolar bodies in the NOR region during nucleologenesis. However, their physical coalescence between themselves is increased, as shown in Allium cepa L. meristems.
