In flowering plants, signals generated by the female gametophyte are involved in guiding the pollen tube to the embryo sac exactly.Previous studies showed that the synergid-secreted cysteine-rich polypeptides LURE attract pollen tube in Torenia fournieri and Arabidopsis thaliana.Furthermore, the egg apparatus-expressed diffusible peptide EGG APPARATUS 1 was identified as the pollen tube attractant in Zea mays.
