Abstract (en)

[origin: WO0071736A1] Methods of genetically manipulating biologically active 4'-<i>O</i>-methylated isoflavonoids have been found based upon the regiospecifity of isoflavone 7-OMT in vivo. Upon transformation and expression of an isoflavonoid <i>O</i>-methyltransferase gene, up-regulation of IOMT in the transgenic plants can be used to increase the accumulation of 4'-<i>O</i>-methylated isoflavonoid phytolalexins, providing for increased disease resistance to the plant. Similar methods can be used to increase accumulation of 4'-<i>O</i>-methylated isoflavonoid nutraceuticals in plants. For down-regulation of IOMT in plants that naturally make 4'<i>O</i>-isoflavonoid phytoalexins and 4'-<i>O</i>-methylated isoflavonoid nutraceuticals, IOMT gene sequences can be transformed in the antisense orientation.
