  • Method for producing transgenic plant having increased content of 20-hydroxyecdysone using insect-derived gene and plant produced by the same
    Patent number: 11326181
    Abstract: A method for producing a transgenic plant having increased content of 20-hydroxyecdysone according to an embodiment of the present invention may use insect-derived gene A method according to an embodiment of the present invention includes transforming a plant cell with a recombinant vector including at least one of a gene encoding short-chain dehydrogenase/reductase (SDR) protein and a gene encoding C-14 hydroxylase protein, a gene encoding C-25 hydroxylase protein, a gene encoding C-22 hydroxylase protein, a gene encoding C-2 hydroxylase protein, and a gene encoding C-20 hydroxylase protein derived from insect, and regenerating a plant from the transformed plant cell.

  • Method for producing transgenic plant with increased content of 20-hydroxyecdysone using CYP85 gene from and the plant thereof
    Patent number: 10351875
    Abstract: A method for producing a transgenic plant which has increased content of 20-hydroxyecdysone compared to a wild type plant includes transforming a plant cell with a recombinant vector containing a gene encoding CYP85 (cytochrome P450, 85 family) protein derived from spinach (Spinacia oleracea). A method for producing a transgenic plant with enhanced insect resistance includes transformation of a plant cell with a recombinant vector containing a gene encoding CYP85 derived from Spinacia oleracea.
