    Abstract: The invention relates to a method for producing a transgenic tree having reduced xylan content compared to a wild-type tree of the same species, said method comprising reducing expression of one or more genes from the glycosyltransferase 43 (GT43), family in the said transgenic tree, whereby growth properties, mechanical properties, and/or saccharification properties are improved in the said transgenic tree.

    Abstract: Disclosed is a method for increasing saccharification potential in a woody plant and for improving glucose yields in the plant, said method comprising overexpressing a polynucleotide encoding an acetyl xylan esterase polypeptide, wherein the acetyl xylan esterase is of fungal origin and a member of family CE1, in at least one cell type in said plant. Further disclosed is a method for producing a genetically modified woody plant, comprising overexpressing a polynucleotide encoding an acetyl xylan esterase polypeptide, wherein the acetyl xylan esterase is of fungal origin and a member of family CE1, in at least one cell type in said plant, wherein the said plant has increased saccharification potential as compared to a corresponding non-genetically modified wild-type plant. Further disclosed is a genetically modified woody plant overexpressing a polynucleotide encoding an acetyl xylan esterase polypeptide, wherein the acetyl xylan esterase is of fungal origin and a member of family CE1, in at least one cell type in said plant, and wherein the said plant has increased saccharification potential and increased glucose yields as compared to a corresponding non-genetically modified wild-type plant.
