METHODS AND MEANS FOR PRODUCING GLYCOPROTEINS WITH ALTERED GLYCOSYLATION PATTERN IN HIGHER PLANTS

摘要

The invention provides methods to modify the N-glycosylation pattern of glycoproteins in higher plant cells, through reducing or eliminating the level of β(1,2) xylosyltransferase and α (1,3) fucosyltransferase activity and increasing the β(1,4) galactosyltransferase activity in the cell of the higher plant.
