摘要:
This disclosure provides genetically modified plants having desirable levels of sugar release and syringyl/guaiacyl (S/G) ratio; methods of genetically modifying plants to modulate sugar release and S/G ratio; and uses of such plants. The inventors have determined that genetic modification of a laccase gene (LAC2) from Populus, encoded by locus Potri.008G064000 resulted in transgenic Populus trees with changes in syringyl/guaiacyl ratios as well as altered sugar release phenotypes. Plants with altered sugar release, and S/G ratio, based on modulation of the expression or activity of the LAC2 gene, have divergent uses including pulp and paper production, and biofuel and bioproducts production.
