SIGNATURE SIGNALS. “Following pollen tube discharge and plasmogamy, the egg and central cells displayed transient Ca2+ spikes, but not oscillations. Only the events in the egg cell correlated with the plasmogamy. In contrast, the synergid cells displayed Ca2+ oscillations on pollen tube arrival. The two synergid cells showed distinct Ca2+ dynamics depending on their respective roles in tube reception. These Ca2+ dynamics in the female gametophyte seem to represent highly specific signatures that coordinate successful double fertilization in the flowering plants.”
