Lamellate bodies in the nuclei of dragonfly (odonata) oocytes
- 14 Downloads
Concentrically lamellate spherical bodies have been observed in the oocyte nuclei of the anisopterous dragonflyCordulia aenea. In their ultrastructure, these bodies resemble the “cortical granules” reported from the cytoplasm of the sea urchin oocytes. The lamellate bodies ofCordulia are compared with other lamellate systems known to exist in nuclei. It is suggested that the nuclear lamellate spheres ofCordulia may be homologous with the somewhat less regular lamellate bodies described from maize microspores.
