Loss of fertility and X-irradiated Acetabularia

In X-irradiated Acetabularia cells, cysts fail to germinate. However, meiosis of the primary nucleus and mitosis of secondary nuclei take place. The observed loss of fertility could result from a 'late' death effect or from deleterious interaction between nuclei of opposite sign inside mul...

Zusammenfassung:In X-irradiated Acetabularia cells, cysts fail to germinate. However, meiosis of the primary nucleus and mitosis of secondary nuclei take place. The observed loss of fertility could result from a 'late' death effect or from deleterious interaction between nuclei of opposite sign inside multinucleate cysts.
