    摘要: Disclosed are the complete polyunsaturated fatty acid (PUFA) polyketide synthase (PKS) systems from Schizochytrium, and biologically active fragments and homologues thereof. More particularly, this invention relates to nucleic acids encoding such PUFA PKS systems, to proteins and domains thereof that comprise such PUFA PKS systems, to genetically modified organisms (plants and microorganisms) comprising such PUFA PKS systems, and to methods of making and using the PUFA PKS systems disclosed herein. This invention also relates to genetically modified plants and microorganisms and methods to efficiently produce lipids enriched in various polyunsaturated fatty acids (PUFAs) as well as other bioactive molecules by manipulation of a PUFA polyketide synthase (PKS) system.

    摘要: Vaccines for conferring immunity in mammals to infective pathogens are provided, as well as vectors and methods for plastid transformation of plants to produce protective antigens and vaccines for oral delivery. The invention further provides transformed plastids having the ability to survive selection in both the light and the dark, at different developmental stages by using genes coding for two different enzymes capable of detoxifying the same selectable marker, driven by regulatory signals that are functional in proplastids as well as in mature chloroplasts. The invention utilizes antibiotic-free selectable markers to provide edible vaccines for conferring immunity to a mammal against Bacillus anthracis, as well as Yersina pestis. The vaccines are operative by parenteral administration as well. The invention also extends to the transformed plants, plant parts, and seeds and progeny thereof. The invention is applicable to monocot and dicot plants.
