METHODS AND COMPOSITIONS INCREASING CERTAIN AMINO ACID CONTENT IN SEEDS Russian patent published in 2009 - IPC C12N15/82 A01H5/00 

FIELD: chemistry, biochemistry.

SUBSTANCE: plants are transformed with composition with nucleotide sequence including tissue- or organ-specific signs regulating transcription during chosen morphogenesis stages. Signs are linked with chimeric nucleotide sequence not having own stop codon and containing on its C-terminal end codons, coding chosen number and combination of amino-acid residues. Chimeric nucleotide sequence provides directional expression of specific vegetative carrier protein with stable amino acid chain extension. Stability of composition is determined using cell-free system in vitro applying codon cartridges with chosen combination and number of codons.

EFFECT: provided increased content of amino acids in plant tissues particularly, in membranes of seed oil corpuscles and cellular walls thus providing food and fodder compositions.
