Interaction with synergid cell I

Movie 7. Pollen tube interaction with the synergid cell in an  in vitro  guidance assay

Time-lapse imaging of DsRed-tagged pollen tubes entering the ovule and traveling within the ovule before approaching the GFP-tagged synergid cell within the female gametophyte.

Left video, time-lapse images captured in the red and green channels. Right video, time-lapse images captured in the green channel only.

The time elapsed between frames is 10 minutes (indicated on the top left hand corner of each movie).

In this example, the pollen tube arrives at the synergid cell at 120 minutes and synergid degeneration initiates at 200 minutes.
