The present invention is related to a set of genes, which when modified in plants gives altered lignin properties. The invention provides DNA construct such as a vector useful in the method of the invention. Further, the invention relates to a plant cell or plant progeny of the plants and wood produced by the plants according to the inventionLower lignin levels will result in improved saccharification for bio-refining and ethanol production and improved pulp and paper. Increased lignin levels will utilise lignin properties for energy production.The genes and DNA constructs may be used for the identification of plants having altered lignin characteristics as compared to the wild-type.According to the invention genes and DNA constructs may also be used as candidate genes in marker assisted breeding.
