Title: Key gene regulating plant cell wall recalcitrance

This disclosure provides plants having desirable levels of lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens; methods of selecting plants with such desirable levels of lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens; methods of genetically modifying plants to modulate lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens; and uses of such plants. The inventors have determined that the expression and/or activity of POPTR_0014s08530, a gene encoding an Angustifolia/CtBP transcription factor, modulates lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens in plants. Plants with lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens, based on modulation of the expression or activity of the POPTR_0014s08530 gene, have divergent uses including pulp and paper production, and ethanol/biofuel production.
