Article Synopsis
- Ca(2+) waves and oscillations are important signaling components during fertilization in animals and also play a role in double fertilization in flowering plants.
- Researchers successfully imaged Ca(2+) levels in the egg and central cells, as well as the accompanying synergid cells during this unique fertilization process.
- Differences in Ca(2+) dynamics were observed, with the egg and central cells experiencing transient spikes, while the synergid cells exhibited oscillations, indicating their specific roles in coordinating successful fertilization.
In flowering plants, double fertilization is normally accomplished by the first pollen tube, with the fertilized ovule subsequently inhibiting the attraction of a second pollen tube. However, the mechanism of second-pollen-tube avoidance remains unknown. We discovered that failure to fertilize either the egg cell or the central cell compromised second-pollen-tube avoidance in Arabidopsis thaliana.
