(2009) Defensin-like peptides LUREs are pollen tube attractants secreted from the synergid cell.
Thus, it is likely that in ig1 mutants, the non-repressed expression of these genes generate the metabolic alterations needed to promote proliferation in cell types such as synergid or antipodal cells, and embryogenesis in embryo-producing cells such as the egg and the sperm cells after pollen discharge.
Previous research suggested synergid cells, which hug the embryo sac, direct the tubes once they approach the ovary.

It was necessary to change the plane of focus to visualize all cells of the megagametophyte; the egg was frequently obscured by being below or above the plane of a synergid (Fig.
