Abstract: Plant expression vectors comprising an ORF of an isoform gene (?1,4GT5) of human ?1,4-galactosyltransferase were constructed. Then, the vectors were introduced into tobacco using plant gene-recombination techniques, and transformed tobacco was made. Analysis of the obtained transformed tobacco showed that more than 200 ?g of lactosylceramide was produced from 1 g of fresh leaves. Accordingly, the present invention made it possible to mass synthesize lactosylceramide by using recombinant plants.

Abstract: Disclosed herein is a method for extending the sugar chain modification of a lipid or a protein by introducing two or more glycosyltransferase genes in a biological organism (including animal-, plant- or microbial cells). Also disclosed is a recombinant plant with a potency to generate ceramide trihexoside and a method for generating ceramide trihexoside using the plant. Methods for synthetically preparing ceramide trihexoside utilizing a transgenic tobacco prepared by constructing an expression vector with the ORF of human- or animal-derived ?1,4-galactosyltransferase gene (?1,4 GT) for plants and subsequently introducing the vector into tobacco using a genetic approach for plants and methods for the mass-scale production of ceramide trihexoside are also disclosed herein.
