SEEDS OF TRANSGENIC PLANTS WITH HIGH CONTENT OF LYSINE Russian patent published in 2012 - IPC A01H5/10 C12N15/82 C12N5/10 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of biochemistry. Seeds of transgenic corn is described containing more than 4000 parts per million (ppm) of free lysine, where seeds of corn contain native DNA and one or more exogenous cassettes for expression in plants containing a DNA molecule encoding a dihydrodipicolinatsynthase resistant to inhibition by free L-lysine by the feedback principle, the DNA molecule, transcribed to produce RNA molecule, which suppresses lysinketoglutarate reductase/ sugar pindehydrogenase, and a DNA molecule encoding aspartatkinase resistant to the action of lysine-mediated feedback, where the DNA molecules are functionally linked to one or more promoter molecules in such a way that transcription of one or more RNA molecules occurs mainly in the endosperm of corn seed, which, optionally, the corn seed contains an exogenous gene, which confers resistance to herbicides. A method of obtaining corn flour is proposed, including obtaining of the said corn seed and seed processing to obtain flour. Flour is described obtained by this method. Use of the said seed is proposed to produce fine flour or coarse flour, animal feed, obtaining protein concentrate or isolate, and use of this seed by a human or an animal.

EFFECT: invention enables to obtain food products rich in lysine that do not require further addition of lysine.
