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.
Claims29
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, wherein said transgenic tree have increased growth properties and improved mechanical properties, and/or saccharification properties compared to a wild-type tree of the same species.
An expression vector comprising:
- (i) a wood-specific promoter which is active in developing wood;
- (ii) at least one gene, optionally selected from the glycosyltransferase 43 (GT43) gene family.
Dependencies are inferred from the claim text.
