  • Picture of developing WT seeds (Col-0) at 3, 6, 9 and 12DPA
  • Fruits were grown in planta (uncut) or in vitro from 3DPA onwards

  • Note that the file containing the pictures from this experiment was too large for Zenodo, the pictures were thus transformed into 8 bit black/white pictures, a 2x2 binning was applied, before a saving into tiff. The original pictures are available at: http://flower.ens-lyon.fr/
