| Abstract: | Two capabilities are critical in attracting and transporting male gametes for fertilization: (1) the pollen tube must locate,
enter and discharge its contents at the correct site within the female gametophyte, and (2) once inside the embryo sac, the
non-motile male gametes must be transported to the egg and the central cells for double fertilization. This review summarizes
current information about evidence for communication between embryo sac and pollen tube and the means by which the non-motile
male gametes are transported from the aperture of the pollen tube to the site of gamete fusion.
