  • CONSTRUCTION OF PLANT RECOMBINANT GENE EXPRESSION CONTROL PLATFORM
    Publication number: 20210310014
    Abstract: Gene expression is regulated (ON/OFF switching) by regulating the chromatin structure, and a several tens of genes (multigene) set introduced into genetically modified crops is stably expressed by the regulation. A plant recombinant gene expression regulatory platform DNA sequence comprising (1) an artificial alphoid DNA sequence having a hierarchical repetitive structure of an alphoid DNA that forms a centromere of a human chromosome and having a nucleotide sequence a part of which is replaced by a binding site of a gene expression regulator (inducer); and (2) a multigene (a plurality of genes) expression cassette sequence, wherein the artificial alphoid DNA sequence is linked to upstream (5? side) and downstream (3? side) of the cassette sequence; and a method for regulating the expression of a recombinant gene in a plant body using the sequence.

  • Mutein, method for producing said mutein, gene encoding said mutein, recombinant vector and plant bearing said gene, method for controlling amount of mevalonic acid produced and amount of isoprenoid produced, method for controlling 3-hydroxy-3-methylglutaryl-CoA reductase activity
    Patent number: 10590395
    Abstract: Provided is a mutant protein obtained by mutating a specific amino acid residue of HMGR, a rate-limiting enzyme of isoprene monomer biosynthesis in the polyisoprenoid biosynthesis pathway. The present invention relates to a mutant protein, wherein at least one amino acid residue selected from the group consisting of amino acid residues at positions 91, 225, 257, 287, 339, 411, 470, 509 and 574 of the Arabidopsis thaliana 3-hydroxy-3-methylglutaryl CoA reductase shown by SEQ ID NO:1 and amino acid residues at positions corresponding to the foregoing in 3-hydroxy-3-methylglutaryl CoA reductase is deleted or replaced with another amino acid residue.
