The invention relates generally to the expression of desaturase enzymes in transgenic corn plants and compositions derived therefrom. In particular, the invention relates to the production of oils with improved omega-3 fatty acid profiles in corn plants and the seed oils produced thereby. Such oils may contain stearidonic acid, which is not naturally found in corn plants and has been shown to have beneficial effects on health.

Cornstarch characteristics can be changed by expressing a non-corn plant starch branching enzyme in a corn plant. In a preferred embodiment, transgenic corn plants containing the barley starch branching enzyme IIa transgene was generated. Some transgenic corn plants produced seeds containing cornstarch with lowered gelatinization temperature and retrogradation rate while others produced seeds containing cornstarch with higher retrogradation rate when compared to non-transgenic corn plants.

Methods are provided for transforming freshly isolated, immature maize embryos and for producing transgenic maize plants. The methods comprise obtaining immature embryos from a maize plant, contacting the embryos with an auxin-depleted or phytohormone-depleted transformation support medium and introducing a nucleotide construct into cells from the embryos prior to subjecting the embryos to conditions which promote embryogenic-tissue formation. The methods additionally comprise identifying or selecting transformed cells and regenerating such cells into transformed maize plants.

This invention also relates to inbred maize lines derived from inbred maize line PH705, to methods for producing other inbred maize lines derived from inbred maize line PH705 and to the inbred maize lines derived by the use of those methods.

According to the invention, there is provided a hybrid maize plant, designated as 38H67, produced by crossing two Pioneer Hi-Bred International, Inc. proprietary inbred maize lines. This invention relates to the hybrid seed 38H67, the hybrid plant produced from the seed, and variants, mutants, and trivial modifications of hybrid 38H67. This invention also relates to methods for producing a maize plant containing in its genetic material one or more transgenes and to the transgenic maize plants produced by those methods. This invention further relates to methods for producing maize lines derived from hybrid maize line 38H67 and to the maize lines derived by the use of those methods.

The present invention relates to a novel culture system for generating transformed corn plants from mature seeds. In particular, the invention relates to the use of plant hormones during germination to affect the culture response. Transgenic corn plants can then be easily produced.

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.

The subject invention relates in part to the use of insect-protected corn to modify fertility recommendations for given yield targets on any transgenic corn type. The insect-protected plants are unexpectedly more effective at assimilating not only nitrogen but also less valuable nutrients such as phosphorous, potassium and micronutrients such as zinc. The subject invention also relates to the discovery that transgenic corn plants with insect protection traits exhibit drought tolerance. For example, the protected plants are also much more effective at extracting moisture and are therefore more drought resistant and require less supplemental irrigation to produce the same yields as unprotected plants.
