Patterns of DNA synthesis during pollen embryogenesis in henbane
V Raghavan
Continued DNA synthesis in the generative cell nucleus, followed by mitosis
and cytokinesis, results in the formation of pollen embryoids in cultured
anthers of H. niger. In contrast, the nucleus of the vegetative cell
undergoes no DNA synthesis after it is cut off, or synthesizes DNA only
during a limited number of cell cycles. DNA synthetic patterns in the
generative and vegetative cell nuclei confirm the ontogeny of embryoids
described in this plant.
