title: Occurrence of nucleolar material in the cytoplasm of plant cells.
abstract: This paper deals with the induction of cytoplasmic nucleolar bodies in meristematic Allium cepa L. cells after treatment with drugs which interfere with nucleolar functionality. The drugs which interfere with protein synthesis failed to produce these bodies. The ultrastructure origin and physiological significance of these bodies are discussed here, as well as their relation with the mitotic prenucleolar bodies (Moreno-Díaz de la Espina et al., 1976).
