    摘要: Provided is a method for producing transgenic monocotyledonous plants, plant cells, plant parts, seeds, and reproduction material with modified 5-aminolevulinic acid biosynthesis. This is achieved by stably integrating one or several nucleic acid molecules coding for a protein with a 5-aminolevulinic acid synthase function (ALAS) isolated from the alpha group of purple bacteria, an active fragment thereof or an antisense or complementary sequence thereof, into tie plant genome in stable form. This method can also be used to control undesired vegetation Also provided is a method for producing transgenic plants or plant cells whose glutamate-1-semialdehyde transferase (GSAAT) expression is suppressed or inhibited by stable integration of at least one nucleic acid molecule encoding an ALAS isolated from the alpha group of purple bacteria into the plant plastome by plastid transformation.

    摘要: Protoplasts which regenerate reproducibly in a short time to normal, fertile plants can be regenerated from an auxin-autotrophic genotype of Zea mays (L.). Starting from immature embryos on hormone-free media, an auxin-autotrophic, embryogenic callus is formed on the shoot basis of the seedlings, which callus retains its embryogenic potential over a substantial period of time when subcultured on hormone-free medium. In addition to fully-developed embryos, adventitious embryos are also formed under suitable culture conditions (6-9% of sucrose in the medium). When the sucrose content is reduced to 2-3% and 2,4-dichlorophenoxyacetic acid is added, soft, granular calli are formed which consist of embryogenic cell aggregates (type II callus). After subculturing the type II callus in the form of a cell suspension culture, totipotent protoplasts can be isolated. From these protoplasts, the maize plants according to the invention are regenerated.
