Interspecific crossing barriers in Lycopersicon and their relationship to self-incompatibility

Part of the Advances in Cellular and Molecular Biology of Plants book series (CMBP, volume 2)


Fertilization in plants is the culmination of a complex set of processes beginning with the initiation of pollen germination, involving the development of the pollen tube and its interactions with the female sporophyte or gametophyte, and resulting in the production of viable seed. Several mechanisms limit successful fertilization within and between species. The intraspecific mechanisms encourage outcrossing within species, and the interspecific mechanisms affect speciation and limit the exchange of genes between species.
