Title: PtDUF266 gene regulating cell wall biosynthesis and recalcitrance in populus

Abstract

This disclosure provides genetically modified plants having desirable levels of sugar release, cellulose content and reduction of recalcitrance; methods of genetically modifying plants to modulate sugar release, cellulose and lignin contents; and uses of such plants. The inventors have determined that genetic modification of PdDUF266A from Populus, encoded by locus Potri.011G009500 resulted in transgenic Populus trees with changes in lignin and cellulose content as well as altered sugar release phenotypes. Plants with altered sugar release, cellulose and lignin content, based on modulation of the expression or activity of the PdDUF266A gene, have diverse uses including pulp and paper production, and biofuel and bioproducts production.
