摘要： Methods for the production of insulin in plants are described. In one embodiment, the present invention provides a method for the expression of insulin in plants comprising: (a) providing a chimeric nucleic acid construct comprising in the 5′ to 3′ direction of transcription as operably linked components: (i) a nucleic acid sequence capable of controlling expression in plant seed cells; and (ii) a nucleic acid sequence encoding an insulin polypeptide; (b) introducing the chimeric nucleic acid construct into a plant cell; and (c) growing the plant cell into a mature plant capable of setting seed wherein the seed expresses insulin.

摘要： Commercial production of human insulin can be affected via transgenic expression in plant seeds. Thus, levels of insulin accumulation exceeding 0.1% of total cellular protein can be achieved recombinantly, through expression of the insulin with a single-chain antibody as a fusion partner. Production in seeds offers flexibility in storage and shipment of insulin as a raw material, and insulin retains its activity upon extraction from stored seed. Further, the amount of biomass subjected to extraction is limited, due to the relatively low water content of plant seeds.

摘要： Disclosed are novel acyl-CoA synthetases and novel acyltransferases, nucleic acid molecules encoding the same, recombinant nucleic acid molecules and recombinant host cells comprising such nucleic acid molecules, genetically modified organisms (microorganisms and plants) comprising the same, and methods of making and using the same. Also disclosed are genetically modified organisms (e.g., plants, microorganisms) that have been genetically modified to express a PKS-like system for the production of PUFAs (a PUFA PKS system or PUFA synthase), wherein the organisms have been modified to express an acyl-CoA synthetase, to express an acyl transferase, to delete or inactivate a fatty acid synthase (FAS) expressed by the organism, to reduce competition for malonyl CoA with the PUFA synthase or to increase the level of malonyl CoA in the plant or plant cell, and in one aspect, to inhibit KASII or KASIII. Additional modifications, and methods to make and use such organisms, in addition to PUFAs and oils obtained from such organisms, are disclosed, alone with various products including such PUFAs and oils.
