POLLEN-MEDIATED GENE FLOW is the transfer and incorporation of genetic information between distinct plant populations when cross-pollination occurs. PMGF is a natural biological process that occurs to some degree in all flowering plant species, including most major crops. The term "pollen-mediated gene flow" is often used synonymously with "outcrossing" or "cross-pollination." For this paper, however, we define gene flow to have taken place only when the pollination event results in the incorporation of transferred genetic information into the receptor population--that is, the production of viable seed. Gene flow can enhance the genetic diversity of plant populations and ...
