Extract

In flowering plants, pollination and the process of fertilization are complex processes involving a series of cell-to-cell communication events. Though details of the progression of the pollen tube through the pistil, beginning with germination of the pollen grain on the stigma and culminating with delivery of the sperm cells to the embryo sac, are well established for several higher plant species, the mechanisms involved have yet to be elucidated. It has been shown that the transmitting tissue, which coincides with the path of pollen tubes in the gynoecium, is composed of highly secretory cells characterized by an extensive extracellular matrix (ECM). The actual roles that this ECM plays in pollination are currently unknown, although functions proposed include mechanical and/or chemotropic pollen tube guidance as well as pollen tube nutrition.
