Fecha de publicación: 24/11/1998 Fuente: WIPO "pollen" A method for producing transgenic seeds and plants, which comprises isolating, from anthers, microspores in their uninucleate stage and removing tissue in which they are embedded, culturing the isolated microspores in a nutrient solution, transferring foreign genetic material into the isolated microspores to obtain transformed microspores, bringing about complete maturation of the transformed microspores to obtain transformed pollen grains in vitro, pollinating receiver plants with the transformed pollen grains and obtaining seeds from the pollinated receiver plants.
