Transgenic plant with reduced fucosyltransferase and xylosyltransferase activity

Abstract

A genetically modified plant or plant cell with reduced α1,3-fucosyltransferase and β1,2-xylosyltransferase activity compared to a wild type plant or plant cell, wherein less than 10% of the total glycan on a protein produced by the plant or plant cell is α1,3-fucosylated glycan and less than 3% of the total glycan on the protein is β1,2-xylosylated glycan is provided. In one embodiment, the plant or plant cell comprises three T-DNA insertions expressing five copies of RNAi targeting α1,3-fucosyltranserase and three copies of RNAi targeting β1,2xylosyltransferase.

Dependencies are inferred from the claim text.
